[0.17.4] Performance issue in Train GUI

[yugatha]

When the train GUI is opened, it causes a massive FPS drop. I do have lots of trains in the network (around 270) which may be the cause, but it never had the same issue on 0.16.51. FPS drops from 45-50-ish to 22-25, then slowly creeps up to 36 and often drops back to 25-ish. When the GUI is closed it heads right back up to 45-50

running on an SSD, not that that should matter too much
