It typically depends on the type of train you want to run.
Through freights to include intermodal, auto, and other types of unit trains will have 6 axle horsepower (we don't count wheels)
Where locals, TSE's, etc, will have a four axle units.
I have just start an HO 100 scale on a 5 by 9 platform. Have two main tracks with the inter track having some spurs. Most of the curves are 18" radius or 22" radius but do have a couple that are 15" radius.
I looking for the right type of engine to run. I am going to use DC and would like the basic sound but am not going to get into the real fancy stuff.
I don't really understand the difference between the engines that have 12 wheels vs 8 wheels. The used train set I purchase several years ago uses an engine with just 8 wheels and I think that would be an ok type. But I think the new engines are better.
I am a retired BNSF person and of course would like a BNSF engine(s) but again am not looking for somthing really fancy.
Any suggestions? Thanks
