GHH swithers

I model the Katy and Mopac circa 1974-83 in Houston (lower level is MP) and Smithville to Taylor (upper level is MKT).

I’d like to model one of those Galveston, Houston & Henderson switch engines that roamed Houston in the early to mid-1970s. Does anyone have a photo or two for a reference?
