Product Description
The Pyle-National Company of Chicago supplied locomotive headlights, Gyralight oscillating warning signals, cab dome lights, and locomotive electrical connectors to virtually every U.S. locomotive builder — Baldwin, Alco, Lima, EMD, and GE — from the steam era through the second-generation diesel program. According to publicly filed asbestos litigation records, Pyle-National headlight and Gyralight housings allegedly incorporated asbestos-fabric-wrapped lead wiring rated for the high-current incandescent lamps of the era and asbestos millboard heat shielding installed between the lamp socket and the housing’s rear wall. Later sealed-beam upgrades and Gyralight rebuild kits allegedly retained the fabric-wrapped internal wiring. Pyle-National also supplied the multi-pin MU jumper receptacles and cab-signal receiver housings that allegedly contained similar internal asbestos fabric insulation.
Workers Exposed
Railroad electricians at diesel and steam roundhouses allegedly opened Pyle-National headlight housings on 92-day inspections, changed bulbs, replaced Gyralight motors, and disturbed the fabric wire wrap and millboard shielding routinely. Railroad machinists rebuilding damaged nose sections after grade-crossing collisions allegedly removed and replaced entire Pyle-National assemblies. Car maintainers on Amtrak and commuter cab-cars allegedly worked with the same components.
