So I've noticed that HO scale buildings are really big, but look too small next to HO freight cars. For example, the set of 8 Walthers Silos is about the same length as a grain car!
Of course, the problem exists in N, but it isn't as noticeable.
So, who uses HO buildings in N? What mods are necessary besides the obvious door and window sizes? Somethings might scale and work, like brick in HO might be cinderblock in N.
