Just a fun fact and has no real gameplay issue but it is a tiny tiny thing to point out, in the cabs of the 47s on the rear wall where the aws change end box is you'll see a small orange box just below it, it has an unlabeled switch on it with a lock off around it, this switch is the TPWS temporary isolation switch modified onto 47s used on main lines post 1997 seen in game 15 years too early in NTP. Likely hood is the loco dovetail used to model off was mainline certified in the modern day which requires it to have TPWS though it is seen in the cabs of the WSR 47 which may be more plausible however the desk has no driver interface unit (if you dont know what that looks like it's on all vehicles in GWE it's a little silver unit on the desks and cabs it has 2 round lights and one sqaure button usually highlighted as train stop override) which means the switch was most likely just missed by the designers at dovetail.
Wrong orange boxes? Consider yourself lucky. On the German routes we have entire trains 10 years out of time.
