Looking for these locomotives in HO scale

[MLW]

Roundhouse makes or used to make a diesel boxcab track cleaner. I think they had both a powered and unpowered version. Perhaps this is a starting point for your second locomotive?

Hi Andrew thank for the ebay link and the idea about the Rondhouse boxcar.
That's helping as well.
