If so, that would be a real time saver...
When I started there, in 1979, we didn't even have the cabinets. We had hydrants on the columns holding up the shed over Tracks 2 and 3, and I had to bring up the hose truck ( an old baggage truck with racks) with a tractor, from its storage location up the ramp, down the Track 1 platform to the crossing, and back down the service platform between Tracks 1 and 2. Then I would stop opposite each hydrant, and unload a hose, connect it to the hydrant stretching it across Track 2.
Then when the train rolled in, I would walk the length, dumping the air pressure from each car, and then put the hoses in and start watering every other car. Then, walk to the other end again, and water the alternate cars, then remove all the hoses, and repressurize the tanks.
Really had to hustle on that task. If the baggage men got done before me, they would come over to assist, and if I got done before them, I would assist them.
On occasion, the DUT Tower would call me over the speaker, and order me to remove all the hoses from Track 2, if he had to run an engine down that track....now that was a real PITA, in the middle of everything. And after the train departed, had to gather all the hoses and put them back on the truck.
It was real fun in snow and ice conditions. Some of the drain valves on the Heritage tanks came in frozen solid, and would not release the air. Had to use fusees to try to defrost them...
