New York subway pump car added to list

Thanks to Bill Wall for sending me information on a car that was not on the PNAERC list until now: New York City Transit Authority 5001. This is the only "pump car" on the list and it was built for use in pumping out flooded subway tunnels. It was constructed by ACF in 1918 on the same order as car 5000 but unlike that car is not motorized, since it was designed to be shoved into flooded portions of the subway. The above photo, sent by Bill, shows the car when relatively new. Bill writes:

Pump cars are specially outfitted cars that are sent into flooded tunnels to pump  water out.   What makes 5001 unique is that it is equipped with a master controller and ME23 brake valve on each end and  was set up to operate with BMT subway cars of the day.   Later on it was modified to operate with R9 cars.  No other pump car had this feature.

The way the pump train would work is, with power on as far as you could get into a flooded area, the pump car would lead into the flood, going in as far it could go.  The siphon would be dropped down, hoses rigged to go the nearest sewer line (since the sewers are above the subway level)  or simply to the street and water pumped out.    When enough water was pumped out, break it down, move and repeat as needed.

The pump car was  attached usually to 3 reach cars, which were old wooden Q type cars, which were loaded with hoses and other gear, as well as providing some seating for work crews.    There was a bus line, located in the  roof area of the pump cars and the reach cars, that would go all the way through the cars.  The times I was on it, the bus line plug on the rear car would be jumped into one of the electrical panels in the car of the R9 pushing it..   On site, this was disconnected and a heavy duty connector put to a 3rd rail, as everything on the car was 600 volts DC

Control from the  pump car back was an interesting conglomeration.    The pump car had electric portions on the H2 couplers it was built with.  The lead reach car had an H2 coupler on the end coupled to the pump car but the other end had  a Van Dorn, as did the middle car and the “blind” end of the 3rd reach car, which in turn had an H2 coupler with an electric portion to couple to the subway cars.    In areas where the Van Dorns were, there were MU jumper cables.   

Now what really made this train odd was while the pump car was equipped with ME23 brake valves and had the electric brake plug feature, it and the reach cars were all straight air. The electric feature only worked on the subway cars attached to it.  When I operated it, I usually did not bother with the electric brake feature as it was not dependable at the time. Straight air was a bit slower but more reliable when you needed it.

So that's pretty interesting! The only recent photo I could find online of car 5001 is here but it is indeed stored at Coney Island with several other non-revenue cars in the historic collection.

Many thanks to Bill for sending me information on this car so that it can be added to the list. Unpowered equipment like this can be a grey area, and in general I tend not to add unpowered non-revenue equipment unless its design is unique to traction practice (like an interurban freight trailer). But car 5001 is a control trailer, set up with a controller and brake stand, and undoubtedly qualifies.
