I've just played a GWE route in the class 166 and had all the train safety systems active. DSD worked fine and gave me alerts every few minutes but there was no audible ping in the cab before signals, nor were there any alerter sounds to signal amber or red signals ahead. I ran another GWE timetable route in the class 43 HST and it was the same. There were no audible or visual signals for the TPWSIS train protection systems. It seems to work ok in the class 377 on ECW.
