I had an original MP set made in 1963-64, a PA1 engine, and 3 passenger cars. Long gone now, Dad sold off all my trains years ago...When I purchased the MP set, I was unaware that AmFlyer had made one. As I like the color blue it was the set I bought.
Now an original is on my wish list.
I have both MP and NP sets re-issued in the early 90's or so, un-run.. I did run them through a couple of loops both forward and backward, and they run flawlessly.Re crappy Lionel passenger sets - I bought a MP passenger set made by Lionel in mid to late 90's. I have not any issues with at all. I do understand that the early Lionel sets were crappy. I must have been lucky.
