Who makes the best O-gauge trains and accessories?
This is something that’s 100% opinion based. It all depends on what your tastes are and what you look for in the trains/accessories that you buy. Personally, I don’t really have a definite favorite. Most of my set is MTH these days, but I enjoy adding pieces from Lionel, Atlas, Weaver and other manufacturers as well. Truthfully, I tend to go through phases. I’ll buy all MTH for a while, and then it’s nothing but Atlas stuff for a few months and so on and so on. This is strictly my opinion, but I see the difference manufacturers like this: MTH makes great stuff and I like them because they make a lot of modern equipment. Lionel makes great stuff, but they seem to me to focus more on the past with big steamers, sleek diesels and older rolling stock. When they do make modern items, they are always nice. Atlas makes a good mix of everything and I like their attention to detail. In general, I find Atlas to have more detail than Lionel or MTH. Weaver strikes me as being for the serious model
