Nuttall Custom Heavy-Duty Gearing for Transit Rail Cars
The New York City Subway is one of the most extensive public transportation systems
in the world with 842 miles of track, 468 stations and over 6,200 rapid transit
cars. Keeping the vast fleet of rolling stock in-service is a never-ending task. Rigid
maintenance schedules are followed to prevent car shortages that could negatively
impact ridership capacities.
Each transit car has four traction drive gearboxes which are mounted to the axles and
driven by electric motors. After years of rugged service, some of the gearing inside the
gearboxes needs to be replaced due to normal wear.
Nuttall Gear was selected to provide replacement gear and pinion sets for the transit
car gearboxes. Superior machining capabilities and exceptional quality control
procedures allow Nuttall to produce the complicated gear/pinion sets which were
custom-engineered by the traction drive OEM.
Nuttall has been producing replacement pinion and gear sets for mass transit
applications for over 25 years.
