Mixed Freight posted:Eric Hall posted:I see in the MTH 2018 catalog some Premier Diesel Engines are offered with Hi Rail wheels and some with Scale Rail wheels. All the engines I have bought in the past are PS2 so I am not sure what wheels they have. Any limitations on the track I choose for my layout if I buy Hi Rail or Scale wheel engines?
I too have been a little confused at times. Seems like I've seen ads (not sure if MTH or maybe Lionel?) for "3-Rail Wheels", "Hi-Rail Wheels,", and "2-Rail Wheels".
The 2-rail wheels are obvious (scale contours), but what's the difference between "3-Rail Wheels" and "Hi-Rail Wheels"?

I'm a newbie so I can't answer your question. Maybe one of the other guys can take it.
