It's no secret, one can only drive an Electrostar in this game so often before it gets repetitive. However, I feel that a trip to the Network Southeast era would boost the potential of the route. Class 33s would allow the use of an existing model, and give users something else to do besides rolling down a heritage railway. In terms of variations, NSE or BR blue would be welcome. Class 423: Slamdoors were the lifeblood of Southern Region commuters for decades, and an iconic type of rolling stock that exist in preservation, but never return to their old stomping grounds. Likewise, these could also be BR blue.
What fits are Class 73 Electro-diesel Spoiler: Class 73 MU code It has two SR EMU system for Class 423 (4VEP) 4CEP (411) 4CIG (421) Class 33/1 Diesel Mode Blue Star WSR Class 33 NTP Class 40 & 45 TVL Classes 31 20 & 37/5 WCL Class 37/5 4CIG 4CEP 2EPB
Something like Charing Cross to Tonbridge with a 4-VEP and a Class 465 (as built) would be fun. Plenty of scope for the 4-CEP and 4-EPB as additions also. Not sure if this is possible, but it would be fantastic to have a port of the AP Class 411 into TSW.
