The 100k passenger update - a Beta branch patch — Iron Roads Steam update #550650

A tester recently shared an interesting save game with around 100k passengers and cargo units on the board. Unfortunately it was running a little slowly, but it has been a great test case to improve performance. This update to the `beta` has a number of performance improvements for large games. It also fixes: A bug that could cause inconsistent train display, and eventually a crash (introduced on the `beta` branch) UI scaling on larger screens A bug that could double charge for track when extending platforms Thanks to all those who have given us feedback on the current `beta`, please keep it coming! If you have not yet tried the preview of Beta 3 and would like to, there are notes on how here.
