or the SP, do not forget in its heyday SP was bigger and more important than UP, why has this magnificent beast been forgotten by one of the trainz greats(norfolksouthern37, anl, lilb, bdaneal, and stevelerro)?
1. Steve Lerro & Bill Kline -> http://kltrainz.com/mt4.html
(Southern Pacific MT-4, good running, looking, sounding trainz model)
2. Jointed Rail Diesel -> http://jointedrail.com/index.php/payware/fallen-flags/southern-pacific.html
Southern Pacific Diesel, weather you want diesel or not it was NOT forgotten. (with the fictional Russia Iron Jacket Boiler 4-10-2)
3. Brian's SP 4-10-2 -> http://jointedrail.com/index.php/payware/steam-transition-era/sp-4-10-2.html
Probably one of the best scripted JR locomotives out there
