I rode behind a similar one at the Portland Narrow Guage RR Museum in Maine. It was a 22 tonner GE with 150 horsepower, but it had two two-axle trucks ( B-B, or 0-4-4-0 in steam terms) with a two foot guage. The body was about the same so I’d imagine yours was just a different set up from the same family.
We have an almost identical engine at Golden Spike for hostling cold steam locomotives. It used to be construction yellow but now has been repainted in a tasteful National Park Service brown. It runs great.

ps - last fall we received a truck load of wood for our wood burner. The truck got stuck backing along the track into the wood yard. So we fired up the 25 tonner and pulled the truck out of the mud. Is that called ‘intermodal’?
Would you believe this spur adjoins my property and I dont even know it’s name? There is virtually no traffic. A month ago a self powered crane car came by. There are a couple of NW-2? Diesels parked nearby with “Cape Cod Railway” on them, but I am sure that is not the name of this track. It runs from East Hartford to the CT/Mass border. We were hoping to turn it into a Rail Trail hiking & biking trail, but the owner shut down those plans. Maybe he is hoping for the same kind of subsidies we give the trucking industry.
One of my favorite railfanning experineces of all time involves two 25 tonners. During the rehab of the D&RGW line that became the Heber Valley tourist railroad, the contractor was moving a single ballast car with two 25 tonners as one could not handle a loaded car on the nearly 2% grade. No MU - just whistles and some occasional yelling between cabs got the job done.
