THis model train stuff is evil and insidious. I have a nice little ho layout I started "for the kids" but as I get into it I notice that the stuff just doesn't take "playing" well. So I thought about the set my dad had and bought a few Marx things. I have a few questions about it. I have heard that while most O stuff is modelled in 1/48,the Marx is closer to 1/64. Can someone confirm this rumor? If I have a reverse loop does it have to have any special wiring like the ho or does the 3 rail system take care of that? What is the best way to make the O-27 track look "real" roadbed, ballasting and weathering? Thanx for any responses.
