Would anyone be interested in the "Photography Game" here?

...or a C40-9 from any road.

What road(s) had them other than Norfolk Southern? I thought everyone else got them with the wide nose.

Ya got me on that one, Brian. For most of the more modern diesels, I have to look 'em up on-line to know the model designation. Still, to keep within the rules, a picture should be anything with the same road name, anything (railroad-related, of course) with the same number, or a similar piece of equipment (i.e. boxcar/boxcar, etc.) as the previous offering.
I'm uncertain as to when we decided that locos should be of a similar model when changing to a different road name, but it seems to have taken hold. Steam locos, on the other hand, can be used interchangeably, regardless of the wheel arrangement.
