Title +Interlocking System Guide +\end_layout + +\begin_layout Section +Introduction +\end_layout + +\begin_layout Standard +In real-world railways, a so-called interlocking system is a set of railway + signals and trackside equipment. + Its purpose is to prevent conflicting train movements which otherwise could + result in derailing or colliding trains. + If you want more information, just search for +\begin_inset Quotes eld +\end_inset + +railway interlocking +\begin_inset Quotes erd +\end_inset + + on the internet. +\end_layout + +\begin_layout Standard +Real-world interlocking systems perform this task by setting routes. + A route is a path along a track that a train can safely pass. + To set a route for a train, the signalman (the operator of a signal box) + has to set switches (turnouts) to the correct position and lock them in + order to make a signal for a train show +\begin_inset Quotes eld +\end_inset + +Proceed +\begin_inset Quotes erd +\end_inset + +. + In newer systems, this is done automatically by the interlocking system. + A route can not be set if switches are locked to a wrong position by another + route or if any portion of the route is occupied by a train. +\end_layout + +\begin_layout Standard +The interlocking system in this Minetest mod tries to follow real-world + interlocking systems as far as applicable. + It divides tracks into track sections and implements a route setting mechanism + following the same principle. +\end_layout + +\begin_layout Standard +However, for the sake of simplicity of implementation and usage, not all + concepts of real-world interlocking have been taken over. + Especially, there is no mechanism for overlap. +\end_layout + +\begin_layout Standard +If you are looking for a place to learn how real-world interlocking systems + work, have a look at +\begin_inset Quotes eld +\end_inset + +SimSig +\begin_inset Quotes erd +\end_inset + +. + By looking at their simulations, you can obtain experience on how to set + up your own interlocking systems in AdvTrains. + The SimSig glossary is a good place to look up unknown terms in this document. +\end_layout + +\begin_layout Section +Setting up track sections +\end_layout + +\begin_layout Standard +In the real world, a line of track is divided into so-called track sections, + or track circuits. + Those systems often can not tell where exactly a train is, but only which + track sections it occupies. + A route can never be set through an occupied track section. +\end_layout + +\begin_layout Standard +A track section often covers: +\end_layout + +\begin_layout Itemize +A section on a main running line, between two signals +\end_layout + +\begin_layout Itemize +A single turnout +\end_layout + +\begin_layout Itemize +A rail crossing, or a set of turnouts acting as a double/single slip switch +\end_layout + +\begin_layout Itemize +A siding +\end_layout + +\begin_layout Standard +You will find some examples on how to interlock certain patterns later. +\end_layout + +\begin_layout Subsection +Track Circuit Breaks +\end_layout + +\begin_layout Standard +In this mod, you will not directly configure the locations of track sections. + Instead, you designate the borders of each track section using a special + node, the Track Circuit Break, abbreviated TCB. +\end_layout + +\begin_layout Standard +For example, if you want to create a track section for a piece of a main + running line, you set up two TCBs at the ends of this track circuit. +\end_layout + +\begin_layout Standard +Setting up a TCB works as follows: +\end_layout + +\begin_layout Enumerate +Place a TCB node somewhere near the place where the circuit break is going + to be located. +\end_layout + +\begin_layout Enumerate +Right-click the TCB node +\end_layout + +\begin_layout Enumerate +Punch the rail which should act as TCB +\end_layout + +\begin_layout Standard +The result should look like this: +\end_layout + +\begin_layout Standard +\begin_inset Graphics + filename lyx_img/screenshot_20180830_142551.png + width 10cm + +\end_inset + + +\end_layout + +\begin_layout Standard +Now you have assigned the TCB node to a rail. + Right-click the TCB node once again. + This will bring up a form which looks as follows: +\end_layout + +\begin_layout Standard +\begin_inset Graphics + filename lyx_img/Bildschirmfoto_2018-08-30_14-26-35.png + width 10cm + +\end_inset + + +\end_layout + +\begin_layout Standard +You see that the form is divided in side A and side B. + To designate where each side is, a marker is displayed on the rail. + You can always make this marker show up by punching the TCB node, and remove + it by punching the marker. + Both sides are shown as +\begin_inset Quotes eld +\end_inset + +End of interlocking +\begin_inset Quotes erd +\end_inset + +. + This means that there is no track section set up at this place. +\end_layout + +\begin_layout Standard +You should repeat this procedure once again a few meters away from the first + TCB to create a second TCB on the same track. +\end_layout + +\begin_layout Standard +\begin_inset Graphics + filename lyx_img/Bildschirmfoto_2018-08-30_14-32-48.png + width 10cm + +\end_inset + + +\end_layout + +\begin_layout Standard +Once you have both bordering TCBs set up, you can now create the actual + track section. + To do this: +\end_layout + +\begin_layout Enumerate +Right-click one of the TCBs +\end_layout + +\begin_layout Enumerate +Locate the correct side (A or B) to create the track section +\end_layout + +\begin_layout Enumerate +Click +\begin_inset Quotes eld +\end_inset + +Create interlocked Track Section +\begin_inset Quotes erd +\end_inset + + in the formspec on the chosen side. +\end_layout + +\begin_layout Standard +Now, the text on the formspec has changed. + It shows something like this: +\end_layout + +\begin_layout Standard +\begin_inset Graphics + filename lyx_img/Bildschirmfoto_2018-08-30_14-27-25.png + width 5cm + +\end_inset + + +\end_layout + +\begin_layout Standard +Clicking +\begin_inset Quotes eld +\end_inset + +Show Track Section +\begin_inset Quotes erd +\end_inset + + brings up another formspec: +\end_layout + +\begin_layout Standard +\begin_inset Graphics + filename lyx_img/Bildschirmfoto_2018-08-30_14-28-32.png + width 5cm + +\end_inset + + +\end_layout + +\begin_layout Standard +On the top, you see a list of all TCBs that border this track section. + In your case, there should be two TCBs listed. + If there's only one, head over to +\begin_inset CommandInset ref +LatexCommand ref +reference "subsec:Long-track-sections," + +\end_inset + +. + You should now select a name for the track section, to identify it later. +\end_layout + +\begin_layout Standard +The same procedure is applicable when you create a turnout track section, + except that you have to set up three or more TCBs. +\end_layout + +\begin_layout Standard +The AdvTrains interlocking system allows you to add more TCBs after you + have created a track section. + This works without problems in most cases. + For example, you can easily insert a turnout into an already set-up track + section and create another TCB behind it, and AdvTrains will automatically + detect the existing track section. + Problems arise only if you try to insert a TCB in-between a section, in + which case both sides of the TCB will end up assigned to the same section. + The code currently does not handle this case properly, so try to avoid + this situation by all means. + As a last resort, you can always dissolve a faulty track section, as described + in the next chapter. +\end_layout + +\begin_layout Subsection +Long track sections, crossings and other edge cases +\begin_inset CommandInset label +LatexCommand label +name "subsec:Long-track-sections," + +\end_inset + + +\end_layout + +\begin_layout Subsubsection +Very long track sections +\end_layout + +\begin_layout Standard +If you try to set up a track section that is longer than 1000 nodes, advtrains + won't recognize the TCB at the other end because of a safety limit in the + traverser function, which is supposed to prevent deadlocks. + This case has happened when the Track Section overview screen only shows + one TCB in the list. + The procedure for this is as follows: +\end_layout + +\begin_layout Enumerate +Go to the second TCB (the one that wasn't recognized). + It should show +\begin_inset Quotes eld +\end_inset + +End of Interlocking +\begin_inset Quotes erd +\end_inset + + on the relevant side. +\end_layout + +\begin_layout Enumerate +Click +\begin_inset Quotes eld +\end_inset + +Create interlocked track section +\begin_inset Quotes erd +\end_inset + +. + The section created will be different from the one that is already present. +\end_layout + +\begin_layout Enumerate +In the track section overview, click +\begin_inset Quotes eld +\end_inset + +Join into other section +\begin_inset Quotes erd +\end_inset + + +\end_layout + +\begin_layout Enumerate +Go back to the first TCB, bring up the Track Section overview screen of + the first track section and click +\begin_inset Quotes eld +\end_inset + +Join with ??? +\begin_inset Quotes erd +\end_inset + + +\end_layout + +\begin_layout Standard +The other, missing TCB should now appear in the list. + If you accidentally started such a joining procedure, click the +\begin_inset Quotes eld +\end_inset + +X +\begin_inset Quotes erd +\end_inset + + button on the right. +\end_layout + +\begin_layout Subsubsection +Rail crosses +\end_layout + +\begin_layout Standard +Since rail crosses are created by laying tracks across each other without + logical connection, there's no way for advtrains to know whether rails + cross each other. +\end_layout + +\begin_layout Standard +Rail crossings in interlocking systems are always one single track section, + which in most cases has 4 TCBs adjacent. +\end_layout + +\begin_layout Standard +\begin_inset Graphics + filename lyx_img/Bildschirmfoto_2018-08-30_14-51-25.png + width 5cm + +\end_inset + + +\end_layout + +\begin_layout Standard +The procedure is quite similar to the one for long sections: First, create + two track sections for the branches, and then use the +\begin_inset Quotes eld +\end_inset + +Join +\begin_inset Quotes erd +\end_inset + + function to merge both sections into one. +\end_layout + +\begin_layout Subsubsection +Deleting and re-adding single TCBs to a section +\end_layout + +\begin_layout Standard +In some occasions, for example when you remove a siding or a crossover, + it can be necessary to unassign a TCB from a track section. + There are multiple ways to do this: +\end_layout + +\begin_layout Itemize +In the TCB form, click the +\begin_inset Quotes eld +\end_inset + +Remove from section +\begin_inset Quotes erd +\end_inset + + button +\end_layout + +\begin_layout Itemize +In the track section form, first select the TCB in the list and then click + +\begin_inset Quotes eld +\end_inset + +Unlink selected TCB +\begin_inset Quotes erd +\end_inset + + +\end_layout + +\begin_layout Standard +The result is that the TCB shows +\begin_inset Quotes eld +\end_inset + +End of Interlocking +\begin_inset Quotes erd +\end_inset + + and the section does not list the TCB as an endpoint anymore. +\end_layout + +\begin_layout Standard +The other case is adding a siding or a crossover, in which case one or more + TCBs still show +\begin_inset Quotes eld +\end_inset + +End of Interlocking +\begin_inset Quotes erd +\end_inset + + although they should be part of a section: +\end_layout + +\begin_layout Itemize +Go to another TCB that is registered in the track section and click +\begin_inset Quotes eld +\end_inset + +Update near TCBs +\begin_inset Quotes erd +\end_inset + + +\end_layout + +\begin_layout Itemize +If that did not work, follow the procedure of creating a long track section +\end_layout + +\begin_layout Subsubsection +Dissolving sections +\end_layout + +\begin_layout Standard +If you made a mistake setting up something and you don't see any other way + to fix a misconfigured track section, you can always delete it using the + +\begin_inset Quotes eld +\end_inset + +Dissolve section +\begin_inset Quotes erd +\end_inset + + button. + This operation removes the track section and sets all TCBs that previously + belonged to the section as +\begin_inset Quotes eld +\end_inset + +End of Interlocking +\begin_inset Quotes erd +\end_inset + +. + This will always work and lets you start over new with setting up track + sections. +\end_layout + +\begin_layout Subsection +Interlocking patterns +\end_layout + +\begin_layout Standard +This section shows some examples on how you should set up track sections + on certain track configurations. +\end_layout + +\begin_layout Section +Signals and routes +\end_layout + +\begin_layout Standard +The purpose of signals is to inform trains about whether they can proceed + into the next section safely. + Making a section of track safe to pass for a train, turnouts need to be + set to the correct position and no other train should be allowed to cross + or share parts of the route with this train. +\end_layout + +\begin_layout Subsection +Assigning Signals to TCBs +\end_layout + +\begin_layout Standard +Signals in the advtrains interlocking system are positioned - like in real + life - at the border of track sections. +\end_layout + +\begin_layout Standard +When you set up a signal, do the following steps: +\end_layout + +\begin_layout Enumerate +If not already happened, set up a TCB (you don't need to, but are advised + to, configure track sections there) +\end_layout + +\begin_layout Enumerate +Place the signal a few meters in front of the TCB, so that trains stopping + at the signal do never pass the TCB +\end_layout + +\begin_layout Enumerate +Locate the side of the TCB which points in the direction that trains will + proceed past the signal, as shown in the figure below. +\end_layout + +\begin_layout Enumerate +Right-click the TCB, and click +\begin_inset Quotes eld +\end_inset + +Assign a signal +\begin_inset Quotes erd +\end_inset + + on this side. +\end_layout + +\begin_layout Enumerate +Punch the signal. +\end_layout + +\begin_layout Standard +\begin_inset Graphics + filename lyx_img/assign_signal.png + width 8cm + +\end_inset + + +\end_layout + +\begin_layout Standard +You can assign a signal to each side of a TCB. + This is, for example, useful when creating block sections on a bi-directional + main running line. +\end_layout + +\begin_layout Subsection +The concept of routes +\end_layout + +\begin_layout Standard +A so-called route is a locked path between two signals, which locks all + turnouts in the correct position. +\end_layout + +\begin_layout Standard +Example: Imagine a station with 2 platforms on a single track running line. + We are looking at signal A. + You probably want trains coming from the right to go into platform 1 or + into platform 2, so you need to program 2 routes. +\end_layout + +\begin_layout Standard +\begin_inset Graphics + filename lyx_img/route_ex1.png + width 7cm + +\end_inset + + +\end_layout + +\begin_layout Standard +This leads us to the most important aspect of route programming: Routes + always start at a signal (A) and end at a signal facing in the +\series bold +same direction +\series default + (D and E), not at an opposite-facing signal (B and C). + There are only few exceptions, we'll cover this later. +\end_layout + +\begin_layout Standard +When you set a route to make a train proceed on it, the interlocking system + ensures that: +\end_layout + +\begin_layout Itemize +There are no rail vehicles on the route +\end_layout + +\begin_layout Itemize +All turnouts are set to the correct position and it is impossible to move + them +\end_layout + +\begin_layout Itemize +No other routes can be set that would in any way conflict with this route +\end_layout + +\begin_layout Standard +For this to work, you need to specify all track sections the train will + pass along, as well as the positions of all turnouts that need to be locked. + Those are not only the turnouts that lay directly on the train's route, + but also some turnouts on adjacent tracks, the so-called flank protection. +\end_layout + +\begin_layout Standard +The purpose of flank protection is to prevent runaway trains and/or wagons + to pass into a route. + This is achieved by setting nearby turnouts to a position that points +\begin_inset Quotes eld +\end_inset + +away +\begin_inset Quotes erd +\end_inset + + from the route. + Example: +\end_layout + +\begin_layout Standard +\begin_inset Graphics + filename lyx_img/route_ex2.png + width 7cm + +\end_inset + + +\end_layout + +\begin_layout Standard +The upper turnout, of course, needs to be locked in straight (normal) position, + while the lower one is not relevant for the route itself. + But what if the lower turnout was set to the diverging (reverse) position + and the driver of another train approaching signal B fails to see the red + light? This train would crash into the first one. + To minimise danger, that other train would need to be routed towards signal + D. +\end_layout + +\begin_layout Standard +There are, of course, situations, where both positions of a turnout would + conflict with a route equally. + In those situations, there's nothing you can do and no flank lock needs + to be set. +\end_layout + +\begin_layout Subsection +Shunt routes +\end_layout + +\begin_layout Standard +Operating railways is not all about driving trains around. + Coupling, decoupling and moving single engines, wagons or groups of wagons + across a station, called shunting, also plays an important role. +\end_layout + +\begin_layout Standard +Remember what we said about routes: There must be no rail vehicles on the + route. + So what if you have some goods wagons ready on a siding, and want to couple + an engine to it? You can not set a regular route into the siding, because + it is occupied. +\end_layout + +\begin_layout Standard +The solution is to program a second route into the siding, but with the + difference that it already ends at the rear-facing signal of it, so it + doesn't include the siding section itself: +\end_layout + +\begin_layout Standard +\begin_inset Graphics + filename lyx_img/route_ex3.png + width 7cm + +\end_inset + + +\end_layout + +\begin_layout Standard +The Sht2 route then needs to show a shunt aspect, which instructs the driver + to proceed slowly and watch out for vehicles on the route. + To show a +\begin_inset Quotes eld +\end_inset + +free +\begin_inset Quotes erd +\end_inset + + aspect here would be wrong, because that would mean that the track is free + until the next main signal, which it is clearly not. +\end_layout + +\begin_layout Standard + +\shape italic +Note that advtrains_interlocking currently does not allow to set individual + aspects for routes, this is a feature still to be implemented soon. +\end_layout + +\begin_layout Standard +Shunt routes like this are, so far, the only exception to the +\begin_inset Quotes eld +\end_inset + +Routes should end at a signal facing the same direction +\begin_inset Quotes erd +\end_inset + + rule. +\end_layout + +\begin_layout Subsection +Route Release +\end_layout + +\begin_layout Standard +In early real-life interlocking systems, routes either had to be cancelled + by the signalman after the train had passed the route, or there was a single + release contact at the end of the route. + However, as interlocking systems evolved and the position of trains is + now roughly known by the track sections, portions of the route can be freed + as soon as the train has left the corresponding section. +\end_layout + +\begin_layout Standard +AdvTrains has chosen a modern approach to route releasing. + Each turnout lock is associated to a track section belonging to the route's + path. + Once the train leaves this section, all assigned locks are also freed. +\end_layout + +\begin_layout Subsection +Programming a route +\end_layout + +\begin_layout Standard +The route programming procedure is quite straightforward if you've read + the previous sections and understood how routes should be set. +\end_layout + +\begin_layout Standard +Routes always start at a signal. + You must have assigned the signal to a TCB, as described earlier. +\end_layout + +\begin_layout Standard +When you right-click the signal, it no longer changes its aspect. + Instead, a formspec pops up, showing you an (empty) list of routes with + the possibility to set them or to create new routes. + Click the +\begin_inset Quotes eld +\end_inset + +Create new route +\begin_inset Quotes erd +\end_inset + + button to start programming a new route. +\end_layout + +\begin_layout Standard +The form closes, and an arrow is displayed on the TCB. + You are now in +\begin_inset Quotes eld +\end_inset + +Route Programming +\begin_inset Quotes erd +\end_inset + + mode, programming the first track section of the route. + Now: +\end_layout + +\begin_layout Itemize +Put any turnouts you need to lock in the correct position (e.g. + by right-clicking them). + This includes flank protection. +\end_layout + +\begin_layout Itemize +Punch them. + This makes a marker saying +\begin_inset Quotes eld +\end_inset + +Route Lock Editing +\begin_inset Quotes erd +\end_inset + + appear. +\end_layout + +\begin_layout Itemize +If you punch a turnout again, or punch the marker, you can remove the lock + again. +\end_layout + +\begin_layout Itemize +When you've locked all turnouts in the current section, go to and punch + the TCB that is the border to the next track section the train proceeds + into. +\end_layout + +\begin_layout Standard +Once you've done this, the lock markers change to +\begin_inset Quotes eld +\end_inset + +Route Lock +\begin_inset Quotes erd +\end_inset + +, telling they can't be changed anymore. + Repeat the above procedure until you have punched the final TCB, at which + the route should end. + As mentioned before, there should be a signal at this place, however this + is not enforced. + Now, run the chat command +\family typewriter +/at_rp_set <name of route> +\family default + to complete programming the route. +\end_layout + +\begin_layout Standard +A few hints: +\end_layout + +\begin_layout Itemize +If one turnout should be locked by more than one section, set the lock only + in the +\family typewriter +\series bold +last +\family default +\series default + of those sections. + Locking the same turnout in multiple sections of a single route results + in undefined behavior! +\end_layout + +\begin_layout Itemize +If you accidentally punched a TCB, you can run +\family typewriter +/at_rp_back +\family default + to undo this and return to the previous section. + Due to a bug, you have to re-set all locks of this section. +\end_layout + +\begin_layout Itemize +If you want to stop programming the entire route without saving it, run + +\family typewriter +/at_rp_discard +\end_layout + +\begin_layout Section +Interlocking system operation +\end_layout + +\begin_layout Standard +Setting up the interlocking for a portion of a railway network requires + some time, experience and planning, but once done, there's not much to + do anymore to make trains run on your, now safer, railway. + This section covers some useful practices to route trains across your network. +\end_layout + +\begin_layout Standard +At the moment, routes can only be set by clicking the signal or via LuaATC, + except if you use automatic working. + It is planned to control this via the onboard computer and via a +\begin_inset Quotes eld +\end_inset + +signal box +\begin_inset Quotes erd +\end_inset + + view based on the currently broken itrainmap. +\end_layout + +\begin_layout Subsection +Simple route setting and cancelling +\end_layout + +\begin_layout Standard +To set a route, simply right-click the signal, select a route and click + +\begin_inset Quotes eld +\end_inset + +set route +\begin_inset Quotes erd +\end_inset + +. + If there are no conflicts, the signal turns green and the train is allowed + to proceed. +\end_layout + +\begin_layout Standard +It may be possible that the route can not be set, because one or more other + routes conflict with the current one, or a section is blocked. + In this case, the signal stays red, and the conflicting item is shown in + the formspec. + As soon as the conflict is resolved (by cancellation or release of the + conflicting route, or the section becoming free), the requested route will + be set and the signal turns green. +\end_layout + +\begin_layout Standard +If a route is either requested or set, it can be cancelled from the signalling + formspec. + This means that all turnouts and sections are released, and the signal + reverts back to red. + This of course only works when the train has not passed the signal yet. + There is no mechanism for Approach Locking. +\end_layout + +\begin_layout Subsection +Automatic Working +\end_layout + +\begin_layout Standard +Block signals on main running lines usually only have a single route to + set, the one proceeding along the main line. + Their purpose is only to show whether there are trains in the next section. + So, it would be convenient if this only route would set itself again after + a train passed. +\end_layout + +\begin_layout Standard +This is what Automatic Working is for. + Set a route, click +\begin_inset Quotes eld +\end_inset + +Enable Automatic Working +\begin_inset Quotes erd +\end_inset + +, and as soon as a train passes, the route is automatically re-set. +\end_layout + +\begin_layout Standard +This function is nearly identical to SimSig automatic signals. + It can also be useful on a line with high traffic, when there's a low-frequente +d access to a siding. + You'd enable automatic working for the main route and cancel it only when + you need a train to go into the siding. +\end_layout + +\begin_layout Section +Final notes +\end_layout + +\begin_layout Standard +The interlocking system is mainly finished, though there are still some + plans and ideas. + They include: +\end_layout + +\begin_layout Itemize +Setting routes from inside a train (via onboard computer) +\end_layout + +\begin_layout Itemize +Signalbox panels, as revival of itrainmap +\end_layout + +\begin_layout Itemize +Individual signal aspects for routes +\end_layout + +\begin_layout Itemize +Distant signals +\end_layout + +\begin_layout Itemize +On-Train head-up display for oncoming signals (they have something like + this in Czech Republic, I forgot how it's called.) +\end_layout + +\begin_layout Standard +Apart from this, there's the large oncoming project of a new timetable-based + train automation system, but this will take some time to evolve and is + out of the scope of this document. +\end_layout + +\begin_layout Standard +If you have any suggestions, corrections, improvements, criticism or cute + kittens and stuff, you can always contact me by various means (Forum PM, + E-Mail (orwell@bleipb.de), Linuxworks server chat a.s.o.). + Have fun!
