You know you are a motor mouth when you start responding to your own posts I guess. Anyway here is a little more info on the later days of the SVRy. Jeff as you already know I am sure the Eng. 100 shows as retired AFE 441 5-8-37, but nothing new with respect to when it left S.Baker. SVRy 101 made it's last official run on 11-28-61. It's retirement date is 1-1-62 with no AFE# listed. It remained at S.Baker till 12-4-63.
Also OLC Heisler #100 was not scrapped till 1954, so it would be interesting to know what part it might have played in scrapping the mainlines. What a shame this engine was scrapped. It was built in 1924 and weighed in at 50 tons on 2 outside frame trucks. Sporting a cross compound air pump, a Rushton stack and outside frame trucks this was an unusual looking engine.
The following cars per John Lewis's research were used to scrap the mainline. They all have retirement dates of 6-30-49 so presumably this was just after scrapping was completed. They are Flat 767 which was converted to a hog fuel crate in 12-39, flat 76411, flat 76413, 74417, 76408, 76501, 76502, 76504, 76507, 508, 517 (another hog fuel crate),5333 a wood rack flat, and 5326 another hog fuel crate.
Other equipment that remained till complete abandonment in 1961 was tank car 100 which was sold to Black Hills Central in 1962. This car however had had the tank removed from the trucks and modified to be towed behind a truck for road watering as I understand it. Cab. 6 also remained at S.Baker till about this time per Mr. Ron Harr when it was sold to a private party. It was officially retired 6-30-47. Flat car 76605 was retired 6-30-47, but remained at S.Baker for MOW and was scrapped in 1962. The dual gauge idler car made from a locomotive tender frame (Tonapah/SVRy #4?) remained at S.Baker and was sold to the Black Hills Central along with OLC #7 in 1962. We have this car at McEwen. That this car remained suggests that there was some thought of being able to use the #7 for moving std. ga. cars if needed. Presumably nothing much was needed for MOW after 1949 as all the remaining 1 1/2 mile of trackage was easily accessable by rubber tired equipment.
Also something I am curious about are the 5 2 gate 16 1/2 cu. yd bottom dump cars built by SVRy in 1939 and retired in 1947. I had heard a rumor once that one of these steel car bodied is still around the area, but no idea where. I have not seen any photos of these cars.
With regard to the OLC7 being an oil burner when it reached Indiana, I had heard that it was converted to back to oil at the BHC.
