1) Cab seat / view heights generally too low in a lot of locos. Class 47, HST, Class 166, Class 52, 101 DMU for definite are too low down and could be a little higher 2) HST doors shouldn’t lock when moving 3) Class 166 Windows should open and Seat height view could be higher 4) Bogie run and brake rub sounds are missing from a lot of British diesel locos. Some like the class 47 are there but nowhere near the volume they should be. There is a lot of preservation work going on at the moment so perfect chance to implement some great improvements here
