Major BIMP ... Renaming Junctions
If you use AI "Drive To Trackmark" or "Drive Via Trackmark", or "couple to"-"railcar number, loco number" ... I have found that naming junctions has no purpose at all !
I re-name ALL my junctions with a "comma" ( ' ) ... ie: "Junction 2036", is just nonsencical info, that just takes up space on the screen.
All AI needs is a switch lever to operate ... AI does not navigate via "junction names".
Drive, Just Drive, Auto Drive, Auto Pilot are also popular AI commands.
