Here's a nice shot of the 1502 sitting in the evening sun at St. Louis Union Station ready to leave with No. 1, The Texas Special, back in 1929. Note the striping on the tender, a little different and more elaborate rendition that what the engines eventually had. Also note the Volatone air horns on the cab roof, right over the engineer's head. Wonder whose idea that was? Nice fishbelly Frisco RPO in back of the engine.
