Question on using O27 track with prewar O G?

RonH posted:

looking to make a small layout on a 4’ X 8’ table.

will have a standard gauge loop on th outside with O27 track on the inside.

I have both O and 027 track. I have two brand new pairs of O27 switches (1122) and the O27 track is new/almost new.

So my question is, will there be a problem running prewar trains on the O27 track, will there be any problems with the switches? The locos will be the 150 series 248 250 and 253. All of my cars freight and passenger are 4 wheel not 8. Some post war will also be run on the track

All those locos and cars will have NO problems operating on the 0-27 track and going thru the 1122 switches.
