2020

- 6976 oil change, test run, and pressed into service

Locomotive #6976 had its lubricating oil drained, which gave us the opportunity to change out the leaky ball valve before refilling it with new lubricating oil, all 275 gallons of it! It took approximately 2.5 hours to transfer one barrel of oil at a time, with a pneumatic pump. New oil and fuel filters were installed, and a new set of unitized batteries went in as well. An annual inspection was completed, and the locomotive was pressed into service.

- 231 electrical and fuel system work leads to successful fire-up!

Locomotive #231 was moved from the display to shop track, where it spent much of 2020 undergoing work on its electrical, fuel, and main reservoir systems. Once the fuel pump and its lines were cleaned of debris, the locomotive was fired up for the first time since 2001! Several main reservoir leaks were identified, as well as a few stuck injectors, which were removed for replacing.
