My Searchlight Wagon Has Arrived Today!!

That’s a nice haul! While the spotlight flatcar is really cool, the two little switchers are what caught my attention. I want to say I remember these from when I was a kid but I might have them confused with a similar engine produced by Bachmann. I’m curious about what real world prototype they’re based on, since side rods are less common on US diesels as opposed to say British or German.
