Alternatively, you can also limit the speed of the train to trigger the routesetting system later, but this is not the ideal solution in most use cases of short routes. + \subsection{Basic three-station setup}\label{s:ilbasicsetup} Now that you have learned to use interlocking, create a simple three-station setup shown below. \begin{centeredtikzpicture}[scale=0.6] |
