Railroad and Transportation Industry Asbestos History

For more than a century, trains, rail yards, repair shops, and transportation facilities relied heavily on asbestos. From locomotive insulation and brake linings to engine gaskets and passenger-car heating systems, asbestos was built into nearly every part of the railroad industry. Workers—including engineers, conductors, mechanics, brakemen, pipefitters, shop employees, and track-maintenance crews—regularly inhaled fibers released from aging or damaged parts.

Today, thousands of railroad workers are being diagnosed with mesothelioma decades after their first exposures.

🚂 Step 1: Why Asbestos Was Used in Railroads & Transportation

Beginning in the late 1800s and peaking through the 1970s, the transportation industry depended on asbestos for its:

• Heat resistance

• Fireproofing abilities

• Durability under friction

• Insulation properties

• Low cost

Since locomotives, engines, and railcars operate under high heat, asbestos became a standard material for everything from boilers to brake blocks.

🔥 Step 2: Asbestos in Steam Locomotives and Engine Rooms

Steam locomotives contained some of the highest concentrations of asbestos in transportation history.

✔ Asbestos-Containing Components Included:

• Firebox insulation

• Boiler jackets

• Steam pipes

• Gaskets and packing materials

• Valve housings

• Turbine and blower insulation

• Engine compartment heat shields

How Workers Were Exposed

• Opening engine housings released clouds of asbestos dust

• Steam leaks damaged insulation, causing fibers to crumble

• Boiler repairs disturbed asbestos cloth and cement

• Workers scraped, cut, and rewrapped asbestos materials

Mechanics, boilermakers, and engineers faced daily exposure.

🚧 Step 3: Diesel Locomotives Also Contained Hidden Asbestos

Many people assume diesel locomotives were safer—but they weren’t.

Asbestos Was Found In:

• Brake shoes

• Clutch facings

• Heating systems

• Exhaust insulation

• Electrical panels

• Engine gaskets

• Flooring and sound-deadening materials

Even modern railroads inherited miles of trackside and yard facilities originally built with asbestos.

🛠️ Step 4: Rail Yard Repair Shops — Highest Exposure Zones

Repair shops were among the most dangerous worksites in the industry.

High-Risk Job Roles

• Machinists

• Mechanics

• Pipefitters

• Millwrights

• Car repairmen

• Electricians

• Welders

• Blacksmiths

• General laborers

Tasks That Released Fibers

• Grinding brake linings

• Removing engine gaskets

• Cutting asbestos insulation for pipes

• Replacing boiler seals

• Welding near deteriorating pipe wrap

• Sweeping contaminated shop floors

Airborne asbestos levels in repair shops often exceeded safe limits by hundreds of times.

🚉 Step 5: Passenger Cars & Transit Systems Also Contained Asbestos

Passenger and commuter rail systems—including subways, streetcars, and light rail—used asbestos in:

• Floor tiles and mastic

• Wall panels

• Ceiling insulation

• Heating and cooling units

• Electrical wiring insulation

• Door and window caulking

Workers at Risk

• Conductors

• Transit mechanics

• Station maintenance staff

• HVAC technicians

• Custodians

• Brake and wheel specialists

Passengers weren’t at high long-term risk—but workers maintaining the systems were.

🛑 Step 6: Railroad Brakes & Clutches — A Major Source of Exposure

Brake systems for trains operate at extremely high temperatures, making asbestos friction materials the standard for decades.

Brakes Contained:

• Asbestos brake shoes

• Asbestos-backed brake pads

• Dust-filled housings

• Heat-resistant linings used during braking cycles

Exposure Occurred When:

• Mechanics blew out brake housings with compressed air

• Grinding machines created airborne asbestos dust

• Workers swept brake debris from floors

• Brake shoes were replaced or resurfaced

Brake work produced some of the most concentrated fiber levels in the railroad industry.

🛤️ Step 7: Track and Infrastructure Exposure

Railroad tracks and related infrastructure were also built with asbestos materials.

Materials Included:

• Asbestos joint compounds

• Electrical signal systems

• Switch heaters

• Communication wiring insulation

• Trackside buildings with asbestos siding and roofing

Workers Affected:

• Trackmen

• Signal maintainers

• Electricians

• Maintenance-of-way crews

• Bridge and building workers

Repairing outdated systems often disturbed asbestos hidden for decades.

🏚️ Step 8: Asbestos in Locomotive Cabins

Inside locomotive cabins, asbestos could be found in:

• Floor tiles

• Heater insulation

• Cushions and padding

• Soundproofing panels

• Electrical boxes

• Control panels

• Roof liners

When these parts degraded, workers in the cab inhaled fibers during every shift.

📦 Step 9: Transportation Warehouses and Supply Rooms

The railroad industry stored massive inventories of asbestos parts.

Warehouses Contained:

• Brake linings

• Insulation rolls

• Gaskets

• Packing sheets

• Cement and plaster

• Electrical components

Workers handling, unpacking, or repackaging these materials inhaled fibers released during routine tasks.

📁 Step 10: How the Railroad Industry Covered Up Risk

Internal documents from multiple rail companies show that:

• Risks were known as early as the 1930s

• Companies continued ordering asbestos products through the 1990s

• Workers were not warned or given protective equipment

• Dust masks offered little protection

• Medical records were often incomplete or suppressed

Many railroad employees were led to believe their work was safe—even though industry leaders knew otherwise.

📑 Step 11: Proving Asbestos Exposure in Railroad Cases

Railroad workers often qualify under FELA (Federal Employers’ Liability Act) instead of traditional workers’ comp.

To build a strong exposure case, gather:

✔ Employment Records

• Job title

• Years worked

• Rail yards or shops where you worked

• Job duties (especially brake, boiler, or engine repair)

✔ Maintenance & Repair History

• Locomotive models worked on

• Brake shoe replacement logs

• Shop work orders

• Track maintenance records

✔ Witness Statements

• Co-worker affidavits

• Supervisor notes

• Testimony about working conditions

Specialized attorneys match these records to known asbestos products used by companies like:

• BNSF

• Union Pacific

• CSX

• Norfolk Southern

• Amtrak

• Local transit authorities

🩺 Step 12: Medical Screening for Railroad & Transit Workers

Because railroad exposure was so widespread, workers should undergo regular screening.

Recommended Tests

• Chest X-ray

• Pulmonary function test (PFT)

• HRCT (high-resolution CT scan)

• Mesothelioma biomarker testing

• Annual monitoring for shortness of breath or persistent cough

Railroad workers are one of the most at-risk groups for asbestos-related disease.
