Product Description
New York Air Brake Company (NYAB) — Watertown NY, today a subsidiary of Knorr-Bremse — was through the 20th century the principal U.S. competitor to Westinghouse Air Brake (WABCO). NYAB supplied complete foundation brake systems to major U.S. freight and passenger railroads including:
- Brake-shoe head assemblies carrying composition brake shoes against the wheel tread
- Foundation-brake rigging — the mechanical linkage of levers, rods, and pins connecting the air-brake cylinder to the brake-shoe heads on each truck
- Slack adjusters maintaining proper brake-shoe travel as shoes wore
- Air-brake cylinders actuating the rigging under train-line air pressure
- Triple-valves and control-valves admitting and exhausting brake-cylinder air
Plaintiffs alleged in publicly filed U.S. asbestos personal-injury and wrongful-death litigation that NYAB foundation-brake assemblies were specified with:
- Asbestos-composition brake shoes (chrysotile-bonded friction material) fitted to NYAB brake-shoe heads
- Asbestos-braided packing at NYAB slack-adjuster pistons and control-valve ports
- Asbestos-cup packing in NYAB air-brake cylinders
- Asbestos gaskets at triple-valve and control-valve flange interfaces
- Asbestos-fiber sheet gasket material at reservoir and pipe-fitting connections
Railroad car repairmen (carmen) and air-brake shop workers were allegedly exposed to respirable asbestos fibers when replacing worn composition shoes, disassembling air-brake cylinders and slack adjusters for periodic rebuild, and scraping old gasket material from control-valve faces.
New York Air Brake has been named as a Manufacturer Defendant in publicly filed U.S. asbestos personal-injury and wrongful-death litigation.
