I wanted to add a little variety to my UP transfer, so I decided to model another locomotive that could be paired with the GP38-2 and would be swapped with the CNW GP15-1.  This project took exactly one week to complete and it helped that I started with a model that had already been detailed fairly well.

I have some old Floquil solvent base paints. going to give airbrushing a shot. [ Badger 350]   what should I use to thin them for airbrushing?   & what ratio paint to thinner.  also air pressure.

I'm trying to update the C&O/PM E7 from Walthers/Proto 2000 to a late 1960's C&O number. I found I easily removed the 'Pere Marquette' and the unit number on the side of the loco by soaking the lettering with Micro Sol for a few minutes and rubbing it off with a Q-Tip. Now, all I have to do is change the number on the numberboard.

The thread on Givens and Druthers got me to wonder about Squares.

The first reference in Model Railroader is in the article 'Doodling By The Squares" by John Armstrong in November 1980

Square is described in - Track Planning For Realistic Operation, Second Edition 1979.  I don't know if it was  in the First Edition 1963 and reprinted a number of times through 1976.
