Posted by HANDBRAKE on Sat Mar 24 23:07:44 2012, in response to Re: And the R-179 contract goes to...., posted by grand concourse on Sat Mar 24 22:02:48 2012. Both CIYD & 207th are overhaul locations for all NYCT & SIR equipment. Most of the cars up on horses at 207th Street have been IRT A Division equipment in part because all but one of the IRT's main line yards are located in the Bronx. IRT cars have easy access via a ramp from the Broadway #1 line into 207th Street YD.207th Street Overhaul Shop is responsible for repairing any problems that pertain to the subway car itself. This will include anything from a simple truck change to major carbody repairs. Along with running repairs, this shop is responsible for maintaining a Scheduled Maintenance System (SMS) program as well. In 2010, the Car Repair Shop was responsible for the SMS on the R-142, R-142A and the R-62 car classes. This consisted of work on all major subsystems of the subway car such as Air Brake, Propulsion, Trucks, Electronics Systems, Doors, Carbody and HVAC. The Car Repair Shop removes components from these subsystems and ships them to the various support shops that then overhaul these items. The parts are then returned to the shop for final assembly on the car and testing. The Car Repair shop also is responsible for replacing any items on the car that cannot be overhauled in a support shop. In the past year they have replaced over 800 trucks, 1200 Door Operators, 700 Modular HVAC units and 800 Propulsion Units while also rebuilding over 900 Draftgears and 50 split system A/C systems. In 2010 a major change to the propulsion system on the R-62 was begun. The original SCM based propulsion system is being replaced with an electronic controlled propulsion system or E-Cam. This requires the replacement of the entire Group Switch Box and Resistor Grid Assemblies. This system was prototyped in 2010 and production was completed on 85 cars with the rest of the cars to be completed this year. The running repair staff also has been instrumental in maintaining the fleet of cars that are owned by the New York City Transit Museum. These cars have been painstakingly restored from years of neglect to bring them back to a state of repair that allows them to be used in passenger service on excursion trips throughout the year and during the Christmas Holidays. While the primary focus of the Car Repair Shop is to keep cars “In Service”, they have also become experts at scrapping cars that have reached the end of their life cycle. Special Projects and Prototypes: •Provided museum cars for excursion throughout the year •Restoration of the museum car 4902 •Car 6660- Removed flip up seats & heaters •Conversion of 85 R62 General Electric group box to an E-Cam system •Salvaged propulsion components from (44) R44 scrap cars to support the R68 SMS program in 2011 |
