In the cabs of all the HSTs in this pack, the cab window is broken. I know there is a fix on UKTrainSim, but is it likely there will every be an actual fix.
For me it only fixes ICS DVT (not DVT2), the GC ones and the IC non-buffered one. There are no changes for the Virgin or NXEC ones.
The start again from the beginning and make sure you follow the instructions to the letter It took me three tries last year when I first got it going. Works on all now
