Jacobpaul:
I understand.
If I were to ever do this, I would hope to avoid the need to paint/decal in order to get what I would like to have in rolling stock. Besides, decals in S scale are not exactly plentiful.
As with this idea I had for Lionel PW, my target era would be the late 1940s. That would leave the door open should I decide to do a PA powered passenger train and such.
If this idea goes much further, there will be much to explore and learn. I don't even know what types of steam engines AF made, nor do I know if most of them smoke/etc. I don't think any of them have whistles, correct?
