That's a pretty amazing roundhouse shot, Steve! Using those locomotive in selection, and perhaps by weathering them extensively, you could make up some fantastic "period" shots. Great models, great picture!
I've been spending most of my time working on rolling stock. Here are some examples. Some are as-purchased, others are kits. The white ones are obviously awaiting time in the painting booth. Brand new RDC from Rapido (with sound)
Atlas RS-3 with sound, relocated horns, steam generator stack in back and MU lines. Damn those railings look way too big.
A mix of a Con-Cor MP54 (with sound), Island Modelworks MP75 (powered with Proto RDC drive), Funaro & Camerlengo M-72, and MT-54. MP-70 double deckers coming soon.
