The limits for every other train seems to be fine, its just the 66 that has this bug where the speed limit on the HUD is lower that what is actually displayed on the speed limit boards. I get that freight trains sometimes have to run slower than passenger trains, but in the video the HUD limit changed from 60 to 50 at the 80mph board, and from 50 to 45 at the 70mph board, which makes no sense because it isn't as split limit board where the limits are different for passenger and freight.
