Four MTA New York City Transit R110A New Technology Train subway cars, originally built by Kawasaki Heavy Industries in 1992 and retired in 1998, are finding new life as two-car pump trains to be used for flooding mitigation in NYCT’s subway system, through a contract awarded to Brookville Equipment Corporation.
The federally funded contract, worth about $22.5 million, includes conversion of the four railcars—originally R110A “A” cars 8001, 8005, 8006 and 8010—into two-car sets consisting of a pump car and generator car. Each will be used in-consist with NYCT’s existing hose-reach cars to pump water out of subway system tunnels during special periods of emergency response, including post-hurricane and periods of unusually heavy rainfall. Each pump car will feature a five-pump arrangement with four inline submersible pumps and one horizontal pump. The submersible pumps will remove the water from a tunnel, while the horizontal pump will extract water in especially low areas when the pump car itself is not submerged. Pumps will be individually controlled through independent motor starters.
Each generator car will utilize an EPA Tier 4 diesel engine/alternator combo to power the pumps and auxiliary equipment, and will also contain an operator control panel, engine start batteries, solar panels and automatic fire suppression system.
The cars will be connected via a 480V, 3-phase trainline system. Additionally, Brookville will supply 480V trainline kits to retrofit the existing hose and reach cars to connect them to the new converted pump and generator cars. All cars will also receive new 70-ton trucks designed for freight applications. In addition to the pump and generator carsets, Brookville will provide testing, training, spare parts and warranty support.
“The pump and generator cars put Brookville in a unique position to leverage its history in transit and underground mining and construction applications to provide this unique emergency-use solution for NYCT,” said Brookville Vice President of Business Development Joel McNeil. “We look forward to synergizing this experience and partnering with our experienced supplier network to deliver a reliable, unique pumping solution that will serve NYCT’s subway system in the coming decades.”
Brookville’s contract is not the first R110A pump car conversion. Between 2013 and 2014, all six R110A “B” cars (8002, 8003, 8004, 8007, 8008 and 8009) were converted into hose-reach cars, as their stainless steel carbodies had many years of remaining service life. A-car 8005 was stripped of parts to become a pump train car, but its conversion was halted as NYCT decided to use only the B cars as hose-reach cars, along with R72 flatcars F219 and F220 as pump cars. The B cars were renumbered P8002–P8004 and P8007–P8009. This pump train (video below) is powered with two MPI (Wabtec) MP8AC-3 diesel-electric locomotives, designated as R156, nos. OL931 and OL932.
The R110A was a prototype car built by Kawasaki Heavy Industries for the NYCT A Division (numbered lines, originally the IRT) consisting of ten cars configured as two five-car sets. They were designed to test features that would be implemented on future railcars, the first of which was the R142A. Bombardier Transportation built an R110B New Technology Train for NYCT’s B Division (lettered lines, wider loading gauge, originally the IND).
