Sir, Your comments about the the S.V.Ry. #101 being gasoline engine powered, are absurd and totally wrong, a fact that shows that your research efforts are incompetent and juvenile in the extreme. I have the original specification sheet for this locomotive which specifically states that the 30 ton Davenport #2245 built in 1937 was powered by a Caterpillar V-8 model D-17000 diesel engine serial number SE-9094 SP which was built by the Caterpillar Tractor Co. Peoria, Illinois.. This an 800 HP engine with 5 3/4" bore x 8" stroke cylinders , Ignition by "Compression". The starter motor was a small 2 cylinder opposed gasoline engine built into the main Diesel engine by Caterpillar Tractor Co. Wheels are 33" in diameter, centers 28", wheelbase 84", designed to be operated on 60 lb. or heavier rail. Minimum radius curve 50' - 0". Maximum tractive effort 20,550 lbs. at 2.9 MPH. 4 gears forward in either direction. Maximum speed in 4th gear15.6 MPH. Unless the D.& R.G. W. put a gasoline engine in the #101 while it was operating and renumbered #50 while at Durango during its several year assignment there, which I am damned sure did not happen, then the #101 is still a diesel at the Colorado Railroad Museum . The locomotive received it's final inspection at the Davenport Plant before Shipment to Baker City, Oregon on April 28, 1937. I have many other facts about this locomotive that are backed by Davenport documentation. Oh yes, the #101 was painted orange when shipped to the Sumpter Valley Railway and operated in that color at South Baker until 1962 when the mill switching line was abandoned and the Oregon Lumber Co. mill shut down. The engine should be repainted that color today and should be renumbered 101. This B.S. that the #101 was primarily a D.& R.G. locomotive is is total fabrication of the real facts. Get your facts in order ! Don't assume anything, in fact the word assume conveys the fact that anybody using it is an ASS!!! ** name redacted to protect the guity **
