I painted outside the train yard from the Diablo side through a chain link fence. The Kansas City Railroad runs the trains in Panama now.
Guys would yell at me as they drove by. Dude, who paints trains? 

 

 

Both unfinished pieces, just blocked in so I could escape the ants gnawing my legs.

The palette is white, yellow ochre, red cad light and ultramarine. I tried a brand of water mixable paints that I like very much - Cobra, an English company - the closest I've come to standard oil paints in texture and feel.
Not having to carry a solvent when traveling is really convenient, particularly overseas where the selection is limited.
