@Geo It is indeed photoshop, photoshop elements, that's all done freehand with the paint and airbrush tools and a lot of patience. The only "cheats" were the lettering tool for all the numbers/reporting marks on the freight cars and the program-generated lens flare. Everything else was done with reference photos, paint brushes and mouse. There's about 150 combined layers in all of that, mix and matched the transparencies and overlays to get the colors right, a lot of it is stuff I drew 2D and then used the transform tool to force perspective on it.
(PSE is a stripped down PS that is meant for photo editing, it doesn't have the ability to vector, or from what I recall, it didn't even have a pen tool)
The other pic of just the idling locomotive was done in an actual copy of PS CS6 with the same basic format, using brushes freehand, but more tip/stroke options.
@Von Clausewitz As far as learning to art (is that grammar right?) No less an authority than Chuck Jones once said that everyone has 10,000 bad drawings in them, the key to being an artist is to draw until you get rid of them. What you see from me is all self-taught trial and error running back 10 years. I highly recommend learning to draw digitally, that way you don't work in fear of making that one big mistake that ruins a piece you'd been 90% of the way done with, having an "Undo" button was a big confidence builder and let me experiment. If you don't have the budget/time for that, I recommend a cheap sketchbook, a cheap pack of pencils, and an afternoon sitting on a street corner or out on a roadside somewhere and just go nuts.
