Confused about size variances in O gauge? Then look here!

Anyone who has looked into the world of O gauge has discovered that there are many sizes. Below are some photographs that I hope will help outline what will size-up with what.
  1. For reference, the MTH Premier Line is 1:48 scale, which is the definition of O scale. All products in the Atlas Big O, Atlas Master, Atlas Trainman, K-Line O Scale, Lionel Standard O, and Weaver lines are also 1:48 scale and match the size of the MTH Premier Line car shown below.
  2. It appears that the Atlas Industrial Rail, K-Line O-27, Lionel Traditional, and MTH Rugged Rails product lines are equal in size and would be classified as being O-27 gauge.
  3. As the pictures show, the MTH Railking Line falls between O scale and O-27 gauge. In fact, there are even three categories within this product line - Railking, Railking Imperial, and Railking Scale. More about this can be read here.
Credit for the images below belongs to a gentleman named Sean from another forum. He did a great job showing the differences


MTH Premier v. MTH Railking


MTH Premier v. Lionel Traditional


MTH Railking v. Lionel Traditional


MTH Railking v. MTH Rugged Rails


Lionel Traditional v. Atlas Industrial Rail


Lionel Traditional v. K-Line O-27


Lionel Traditional v. MTH Rugged Rails


MTH Premier v. Lionel Prewar

I guess they were going for "biggest on the block" with the MTH Premier line.

The picture has a lot of great shadows. It must of been taken late afternoon or the early morning. Plus the fact that it is blown up for a backdrop. Good Find!

Thanks for the help with the scale, now lets talk about the wheels, are the prewar lionel wheels deeper than the post war? or is that the diffence between true O and O-27.
My pre war trains run fine on the fast track until they come up to a switch or accessory track, the rails are not deep enough for the wheels.
thanks
joe

The flanges on the prewar wheels are larger than the flanges on the post war wheels. The prewar crossings don't work well with postwar cars, and vice-versa. The crossing carry the same part number, so you have to test them. I haven't tried 022 switches.
