NNG - SSLV loco and other info

Found this in Wikipedia:
The D-500 runs on standard locomotive tender trucks which are powered through a chain and sprocket drive from an International UD24 engine. The locomotive resembles a caboose, but was built from scratch in Mesita, Colorado on a D&RGW steam locomotive tender frame (D&RGW #964). This was done out of necessity as the railroad could not afford to replace-by-purchase its two ex-D&RGW C-28's (105 and 106) which were on the verge of being condemned.
The D-500 is powered by a 1091 cubic inch International Harvester engine through a hydraulic transmission. This in turn powers an old Euclid truck axle that is used to transmit power to the chains for the axles. It was built as a turret cab for maximimum visibility. All the construction was handled in 1954/55 by SLVS personnel.
The railroad has a second locomotive, a Plymouth ML8 (builder #4161) purchased from Utah Power and Light in 1977. The Gasoline engine was pulled out of it in 1980 so a caterpillar diesel engine could be installed in its place. However the swap was never completed and the locomotive sits derelict without an engine.
Operations of the SSLV ceased some time late in 1994, although the track remains in place (2006). The Property is not abandoned and the current owners are dismayed by the amount of damage being done by thoughtless trespassers who have been stealing equipment off the locomotives and breaking and destroying property.
