Railroad Workers and asbestos exposure
Locomotive insulation, brake shoes and shop repairs exposed rail crews for decades.
- Highest risk period
- Before 1982
- Typical latency
- 20–50 years after exposure
Railroad workers built, ran and repaired the locomotives, cars and track that moved freight and passengers across the country. Steam locomotives were heavily insulated with asbestos, and later diesel equipment and rail cars still used it in brakes, gaskets and heat shielding. Shop crews, machinists, boilermakers, carmen and electricians in rail yards handled these materials for decades. Many started in the steam era and finished on diesels, so their exposure can span very different equipment over one career.
How asbestos became part of the job
In the steam era, locomotive boilers were wrapped in asbestos lagging and cement, and shop workers stripped and replaced it during heavy repairs. Roundhouses and back shops were enclosed, busy spaces where dust from this work built up. As railroads moved to diesel power, asbestos remained in engine gaskets, insulation around exhaust and electrical components, brake shoes, and insulation in passenger cars and cabooses. Car repairmen replaced brake parts and insulation, and electricians worked on components that could contain asbestos. Track and signal workers also encountered it in some materials. Because railroad careers often lasted decades and moved through several job classifications, many rail workers have long, varied exposure histories. Their claims may involve particular federal laws that apply to railroad employees, which is a reason to get case-specific advice.
Materials
Asbestos products this trade handled
The product types that come up most often when this work history is reviewed.
Locomotive boiler lagging
Insulation and cement wrapped around steam locomotive boilers, stripped and replaced during shop overhauls.
Brake shoes
Friction material on locomotives and rail cars that wore into dust during operation and replacement.
Engine and exhaust gaskets
Seals on diesel engines and exhaust systems that were scraped off during maintenance.
Car and caboose insulation
Insulation in passenger cars, cabooses and refrigerator cars disturbed during repair and rebuilding.
Electrical insulation materials
Heat-resistant parts in traction motors and electrical cabinets serviced by shop electricians.
On the job
Tasks that put fibers in the air
Exposure usually came from ordinary, repeated work rather than one event.
Stripping locomotive boiler jackets
Removing old lagging during heavy repairs released large amounts of dust inside roundhouses and shops.
Changing brake shoes
Carmen and shop workers replaced worn shoes, handling friction dust that collected on wheels and rigging.
Rebuilding diesel engines
Scraping gaskets and working around exhaust insulation exposed machinists and mechanics in the shop.
Repairing passenger and caboose interiors
Tearing out old insulation from car walls and floors released fibers in enclosed spaces.
