As said but worded differently MPC is a good product for the most part. Now General Mills did try to come out with some super cheap sets, Mainly 0-4-0 steam engine and small diesel switchers in the shape of NW2 but smaller. They also ( most of them anyway ) where DC power engines and could only run on DC, They did make some that ran on either AC or DC
Here's my opion on trains, if you like them run them. I have from prewar - postwar and then again engines and cars from about 1995 to about 2010. I'm really getting into my prewar Tinplate right now. But like all I have. I've thought about selling some of my trains but when it gets down to it, just can't on about 99% of them.
I don't have a layout at present, so if you do your ahead of me, I need to have some structural things done to this house first.
Just Keep on Training
