This is something I've been pondering for a bit. Why don't the engines and rolling stock all match railway names when you buy a train set? You open the box and you've got a Santa Fe engine pulling a Conrail boxcar and a Lehigh Valley gondola or something. If you're lucky, the caboose might match the name on the engine. If it's a Santa Fe set, why not put in Santa Fe rolling stock? If it's a Conrail set, where's the Conrail engine? If I've got Burlington Northern boxcars, how did I end up with Norfolk & Western on the side of my coal tender? What is the story behind this? Do they just throw whatever they can find at the momment into these train sets or is it a money ploy to make you buy more stuff that matches? It's just odd to me.
