Re: CSI: Alamosa

The Cat Dozer is apparently Cat 531/D-4 Crawler Bucket Loader, and possibly with a rear mounted cavble winch.

Cat 531/D-4 or Allis Chalmers TD-7 as I can not see the total rear of the Loader to make a clear id.

I am curious as to the M of W Number L-?

The Narrow Gauge had from what I have found that three Cat D-4 Dozers assigned in the last years B-26, B-27, B-28.
The D-25 was an American 395 or smaller Crawler Shovel/Dragline Crane (Interchangeable Booms as the Rio Grande was very Frugal/Tight on money and an extra boom was cheaper than another piece of equipmemnt).
The published Work TRain Pictures of 492 running to Rockwood, and the 476? movingt the train to Silverton in 1962.

The Rio Grande made use of the Off-Road Construction Equipment early on, as a picture in one of the later Cinders and Smoke's shows the 463 with a work Train west of Osier with A Crawler Crane/Shovel (the Rio Grande D-12 Bucyrus-Erie Model 10B circa 1936)and Work Train and the date on the picture was approximately 1938.

A great pictures of the Model 10B can be found at AW Equipment Indiana Pa.
