Quite a while ago I replaced the arch bar trucks on my old timey passenger cars (Roundhouse Overton types). I measured them and they scale out to 33". Now I'm wondering if these are correct scale as I see the 33" are usually listed for freight cars and passenger are 36". They work fine and line up perfectly with the loco but I'd like it to be right if possible. Thanks in advance for any help.
