@N&WGuy posted:Here’s the video K&L Trainz did of the “what if” PRR 2-6-6-4: https://m.youtube.com/watch?v=rdRwdGMqDTc
I just realized the #3701 was actually a PRR I1s class 2-10-0, so maybe a number in the 6500’s or 6600’s? Doesn’t seem to have been any Pennsy steam locomotives with those cab numbers! Maybe the #6510? @MrMuffin'sTrains
The cab number in the video shows 6624... maybe 6601?
