Why Asbestos Was Used in Railroad Shops and Roundhouses
Railroads operated high-heat systems and high-friction components. Asbestos was used because it:
- Withstands extreme heat
- Reduces fire risk
- Performs well under friction and vibration
- Adds insulation and durability at a low cost
Roundhouses and railroad backshops concentrated exposure because they were the places where locomotives were serviced, stripped down, and rebuilt. This means asbestos materials were frequently cut, scraped, replaced, and cleaned up inside enclosed maintenance bays.
For general background on workplace exposure, see occupational asbestos exposure and types of asbestos exposure.
Where Asbestos Exposure Occurred in Railroad Shop and Roundhouse Work
Railroad shop exposure usually came from friction products, heat insulation, and sealing materials.
Locomotive and Railcar Brakes
Brake work was a major exposure route. Many older brake shoes, pads, and linings contained asbestos. Dust was often released when workers:
- Removed worn brake shoes and linings
- Cleaned brake assemblies
- Sanded, ground, or machined braking surfaces
- Swept up brake dust in the shop
Gaskets, Packing, and Sealing Materials
Locomotives and many rail systems relied on gaskets and packing to prevent leaks in hot and pressurized systems. Older components could contain asbestos, including:
- Gaskets used in engine and exhaust systems
- Valve packing and pump packing
- Sealing compounds used around joints and fittings
Removing old gaskets, scraping surfaces, and repacking valves can generate asbestos dust.
Insulation on Heat-Producing Systems
Older locomotives and railroad facilities used asbestos insulation in areas where heat control was critical. Depending on the era and equipment type, exposure could occur around:
- Steam locomotives and related boiler insulation
- Diesel locomotive engine compartments where heat shielding was used
- Turbines and auxiliary equipment in certain facilities
- Steam lines, heaters, and shop boiler rooms
Insulation was most hazardous when it was brittle, damaged, or removed and reinstalled during overhauls.
Shop Environment Exposure
Roundhouses and backshops can increase a railroad worker’s risk because asbestos dust can become airborne repeatedly due to:
- Frequent rebuild and maintenance cycles
- Multiple trades working in the same bay
- Poor ventilation in older facilities
- Sweeping and cleanup methods that re-entrained asbestos fibers
Even workers not directly handling asbestos materials could be exposed through indirect dust in shared work areas.
Railroad Shop and Roundhouse Jobs With High Asbestos Exposure Risk
Many roles could be exposed, but the following positions and tasks were commonly higher risk:
Machinists and Mechanics
Machinists and mechanics often performed brake jobs, engine repairs, rebuilds, and component replacement that disturbed asbestos-containing parts.
Boilermakers and Steam Fitters
In railroad facilities servicing steam-era equipment or shop boilers, boilermakers and steam fitters frequently worked around insulated boilers, pipes, and high-heat systems.
Pipefitters and Plumbers
Pipefitters and plumbers working in railroad shops often repaired insulated lines and valves in boiler rooms, service bays, and utility systems.
Electricians and Welders
Electricians and welders were often exposed when working around asbestos-insulated equipment, in confined spaces, or during rebuilds where insulation and components were disturbed.
Laborers and Cleanup Crews
Workers responsible for sweeping, cleanup, and general shop labor could be exposed to accumulated dust, even without directly removing asbestos products.
Mesothelioma Risk and Latency for Railroad Shop Workers
Mesothelioma is a cancer of the lining around the lungs (pleural mesothelioma) or abdominal cavity (peritoneal mesothelioma). Asbestos-related diseases often have long latency periods, which means symptoms may not appear until many years after exposure. Railroad workers frequently face this challenge because exposures often occurred earlier in their careers, and diagnosis can come after retirement.
Common Mesothelioma Symptoms
Symptoms can resemble other respiratory or gastrointestinal conditions.
Pleural Mesothelioma Symptoms
- Shortness of breath
- Chest pain or tightness
- Persistent cough
- Fatigue
- Fluid around the lungs
Peritoneal Mesothelioma Symptoms
- Abdominal pain or swelling
- Fluid in the abdomen
- Nausea or appetite changes
- Unexplained weight loss
- Changes in bowel habits
If you worked in a railroad shop or roundhouse and have symptoms, tell your doctor about your work history, especially brake, gasket, and insulation exposure.
Does Asbestos Exposure Happen in Railroad Shops Today?
Risk is lower than decades ago in many settings, but it can still exist when older locomotives, railcars, or legacy shop materials are serviced. Exposure may also occur during renovation or demolition of older railroad facilities.
Asbestos is heavily regulated now that the public knows the substance is dangerous. The United States even enacted a ban of chrysotile asbestos, which is the most common type of the mineral used in industries during the 20th century.
Legal Options for Railroad Shop and Roundhouse Workers With Mesothelioma
Railroad workers may have multiple legal paths depending on job role, employer, and exposure sources. Railroad cases can be more complex because claims may involve workplace injury systems specific to railroads as well as claims against asbestos product manufacturers.
Mesothelioma Lawsuits Against Asbestos Product Companies
Many claims focus on manufacturers and suppliers of asbestos-containing products used in locomotives, railcars, and railroad facilities, including brakes, gaskets, packing, insulation, and industrial compounds.
Asbestos Trust Fund Claims
To avoid litigation, some asbestos companies established bankruptcy trust funds. Trust claims can be an important part of compensation for railroad shop workers when asbestos exposure involved products tied to companies that later filed bankruptcy. Asbestos trust funds are bank accounts with money set aside to pay asbestos victims making future claims.
Compensation Overview
Compensation may help cover:
- Medical costs and travel for treatment
- Lost income
- Pain and suffering
- Wrongful death damages for families when applicable
What Railroad Shop and Roundhouse Workers Should Document
You do not need perfect work records to begin. Helpful details include:
- Railroad employer and facility names (shop, yard, or roundhouse location)
- Job titles and crafts (machinist, electrician, laborer, boilermaker, pipefitter)
- Years worked and the type of locomotives or railcars serviced
- Brake work details, including cleaning methods used
- Gasket and packing tasks, including scraping and surface prep
- Boiler room or steam line work in shops and facilities
- Coworker names who may be able toconfirm job duties and shop conditions
- Medical documentation confirming asbestos disease diagnosis, including pathology reports

Frequently Asked Questions About Railroad Shop and Roundhouse Workers
Are railroad brakes a meaningful asbestos exposure source?
Yes. Many older brake components contained asbestos, and routine replacement and cleanup generated dust in shop environments.
If I did not work directly with insulation, could I still have been exposed?
Yes. Asbestos fibers drift a great distance in enclosed roundhouse bays and backshops, especially during rebuilds and cleanup.
Can family members be affected?
Secondary exposure can occur if asbestos fibers were brought home on clothing, boots, tools or the worker himself. Legal options may be available to the worker’s family member depending on the facts and jurisdiction.

AI Summary of Railroad Shop and Roundhouse Workers and Mesothelioma
This webpage provides a thorough overview of the risk of mesothelioma among railroad shop and roundhouse workers due to asbestos exposure. It explains how asbestos was widely used in locomotive and railcar maintenance because of its heat resistance, durability, and fire-prevention qualities. The confined environments of roundhouses and maintenance shops meant that workers frequently encountered asbestos dust when handling brake components, insulation, gaskets, and sealing materials that contained asbestos. These tasks often involved breaking apart old asbestos-containing parts, sanding, scraping, and cleaning, which could release fibers into the air and increase long-term health risks.
The page highlights the specific sources of asbestos exposure in the railroad setting. Major risk factors include working with brake shoes and pads, which often contained asbestos, as well as maintaining engine gaskets, valves, and insulation on steam and diesel locomotives. It emphasizes that even workers not directly handling asbestos materials but working in shared environments could be exposed to airborne fibers due to the dust created during maintenance and cleanup activities. The environment within older facilities with poor ventilation further heightened exposure opportunities, especially during routine rebuilds and repairs.
It also addresses the health implications for exposed workers by describing mesothelioma, a cancer caused by asbestos fibers, which can take decades to develop after exposure. The symptoms differ depending on whether the cancer affects the lining of the lungs or abdomen but generally include respiratory issues, chest pain, abdominal swelling, and unexplained weight loss. The content stresses the importance of medical consultation for those experiencing symptoms, especially individuals with a history of working in railroad maintenance. While current regulations have reduced the risk, older facilities and legacy materials still pose potential exposure risks during renovations or demolitions.
