If the speed restriction table does not exist, it is created with the `"main"` speed restriction being the speed restriction value of `train`. + +The `advtrains.speed.merge_aspect` function merges the main aspect of `asp` into the speed restriction table with the same procedure described above. If the signal aspect table does not provide the type of speed restriction, the restriction type `"main"` is assumed. + +# SIDE EFFECTS + +Both functions modify `train.speed_restriction` and `train.speed_restrictions_t`. -- cgit v1.2.3
