With 19's first summer with Tri-State over, it is time to store it for the winter. Locomotives, like your car, are liquid cooled. Unlike your car however, which does not hold over a hundred gallons of coolant, diesels use water, rather than antifreeze. Because of this, water can freeze inside the block in the winter without a block heater, which 19 has never had.
To keep 19 safe for the cold seasons, volunteers drained the several hundred gallons of water from the block, removing drain plugs, draining the cab heaters, opening drain cocks, and shifting the locomotive to make sure water made it out of the low spots and crevices.
In addition, Tri-State member Ron Thrum custom-built a stack cap to fit No. 19, and any upward-facing vents were covered to keep out leaves and snow.
Come spring, volunteers will continue to make improvements, make electrical repairs, and refill and inspect the engine to put it back in service for several planned public appearances in the summer of 2018.
