The PRR had several steam locos that could be made for TS2018. Ideas: -PRR 6-4-4-6 S-1 Duplex (#6100) -PRR 4-4-4-4 T-1 Duplex (#6110-6111; #5500-5549) -PRR 4-6-4-4 Q-1 Duplex (#6130) -PRR 4-4-6-4 Q-2 Duplex (#6131; #6175-6199) -PRR #6200 Steam Turbine These locos need passenger and freight cars plus a PRR caboose. (Interestingly, I've read that the Q-2s were freight haulers.)
