This would be useful outside of stations with double platforms. Currently, if the station is designed to be a passthrough station for a number of lines, there are two crossovers built just outside of each station so the left track can reach the right station platform, and the right track can reach the left station platform.
Adding this to my Train Fever wish list:
1. Roundtables
2. Waypoint system – Useful for many things, such as selecting specific platforms to load/unload or pass through or having a trian use a wye turnaround.
3. “X” double crossover. Useful with heavy traffic, saves space from the current need to build two separate crossovers.
