BNSF Railroad and Asbestos Exposure: Products, Occupational Risks, and Legal History

BNSF Railway Company — the product of successive mergers involving some of America’s oldest rail lines — operates one of the largest freight railroad networks in North America. Across decades of operation under predecessor corporate identities, workers in rail yards, engine houses, and maintenance facilities were routinely exposed to asbestos-containing materials as part of ordinary railroad work. According to asbestos litigation records, BNSF and its predecessor railroads are among the defendants named in thousands of occupational asbestos exposure claims filed across the United States.

This article is intended as a reference for former railroad workers, their families, and attorneys investigating potential asbestos exposure histories connected to BNSF and its predecessor companies.

Company History

BNSF Railway was formed through a series of major railroad consolidations spanning the latter half of the twentieth century. The most significant of these was the 1995 merger of Burlington Northern Railroad and the Atchison, Topeka and Santa Fe Railway, which created what is now known as BNSF Railway Company. Burlington Northern itself was the product of a 1970 merger involving the Great Northern Railway, the Northern Pacific Railway, the Chicago, Burlington and Quincy Railroad, and the Spokane, Portland and Seattle Railway.

Each of these predecessor railroads operated during periods — principally the 1940s through the early 1980s — when asbestos was a standard component of railroad equipment, insulation systems, and building materials used in maintenance facilities. BNSF, as the successor entity, has inherited the litigation exposure associated with those predecessor operations.

Because of the long corporate lineage involved, exposure claims connected to BNSF often involve work performed under the names of predecessor companies. Court filings document claims arising from employment with Burlington Northern, the Atchison, Topeka and Santa Fe, the Great Northern, and the Northern Pacific, among others. Workers, families, and legal representatives researching exposure history should be aware that the relevant employment records and maintenance logs may be held under these predecessor names.

Asbestos-Containing Products and Materials

Plaintiffs alleged, and court filings document, that asbestos-containing materials were present throughout the railroad environment in multiple forms during the mid-twentieth century. While BNSF as a corporate entity did not manufacture asbestos products, railroad operations at the time involved the routine installation, maintenance, and removal of materials supplied by third-party manufacturers — materials that frequently contained significant concentrations of asbestos.

According to asbestos litigation records, the following categories of asbestos-containing materials were documented in railroad settings consistent with BNSF predecessor operations:

Locomotive insulation and engine components. Steam and diesel-electric locomotives of the era were extensively insulated with asbestos-containing materials. Plaintiffs alleged that pipe insulation, boiler insulation, and gaskets aboard locomotives contained chrysotile and/or amosite asbestos. Engine house mechanics and boilermakers who serviced locomotives were routinely exposed during repair and overhaul work.

Brake shoes and friction materials. Railroad brake systems historically relied on asbestos-containing brake shoes to achieve the friction and heat resistance required to stop heavy freight trains. Court filings document that carmen, carmen helpers, and car shop workers who inspected, installed, and replaced brake shoes performed work that generated respirable asbestos dust. This work continued through approximately the early 1980s, when industry conversion to non-asbestos friction materials was largely completed.

Pipe and thermal insulation. According to asbestos litigation records, pipe insulation used throughout locomotive systems, rail cars, and maintenance facilities often contained chrysotile asbestos in preformed pipe covering and block insulation. Pipefitters and general maintenance workers who cut, fitted, or disturbed this insulation were identified in court filings as among the most heavily exposed occupational groups in railroad settings.

Gaskets and packing materials. Plaintiffs alleged that compressed asbestos sheet gaskets and rope packing were standard materials used in locomotive and rail car repair shops. Machinists and mechanical department workers who cut or removed these materials from engines, pumps, and valve assemblies were documented as having routine asbestos contact.

Floor tiles and building insulation. Rail yards and locomotive maintenance facilities frequently contained asbestos-containing floor tiles, ceiling tiles, and spray-applied insulation. According to asbestos litigation records, workers assigned to these facilities — including carmen, electricians, and general laborers — were exposed not only through their primary work tasks but through the building environment itself.

Fireproofing and refractory materials. Court filings document the use of asbestos-containing refractory cements and fireproofing compounds in locomotive fireboxes and shop furnaces. Boilermakers and their helpers who applied or disturbed these materials are identified in litigation records as a particularly exposed occupational group.

Occupational Exposure

According to asbestos litigation records, the railroad industry presented distinctive asbestos exposure conditions that differed in important respects from other industrial settings. Enclosed locomotive cabs and engine house environments could trap asbestos dust generated during maintenance operations, creating elevated airborne fiber concentrations. Workers often performed multiple trades in proximity to one another, meaning that a worker in one trade could be exposed to asbestos generated by coworkers in adjacent areas — a phenomenon referred to in occupational health literature as bystander or para-occupational exposure.

Plaintiffs alleged that the following job classifications were among those with documented asbestos contact in connection with BNSF predecessor railroad operations:

  • Boilermakers and boilermaker helpers — servicing locomotive boilers, fireboxes, and steam systems
  • Carmen and car inspectors — inspecting and repairing freight cars, including brake system components
  • Machinists — overhauling locomotive engines, pumps, and mechanical systems
  • Pipefitters and plumbers — installing and maintaining insulated pipe systems in locomotives and facilities
  • Electricians — working in locomotive electrical compartments containing insulated wiring and components
  • Laborers and general maintenance workers — assigned to shop cleaning, facility maintenance, and material handling
  • Yardmasters and supervisors — spending time in shop environments where asbestos-generating work was performed

Court filings document that railroad workers diagnosed with mesothelioma, asbestosis, pleural disease, and asbestos-related lung cancer have named BNSF and its predecessors as defendants in civil litigation. The Federal Employers’ Liability Act (FELA), which governs negligence claims brought by railroad workers against their employers, has provided the primary legal framework for these claims. FELA claims are distinct from standard workers’ compensation proceedings and allow railroad employees to pursue damages through federal civil litigation.

Exposure under BNSF predecessor companies is particularly significant given the latency period of asbestos-related diseases, which commonly ranges from 20 to 50 years between first exposure and diagnosis. Workers who were employed during the 1940s through the early 1980s may only now be presenting with asbestos-related illness.

BNSF Railway Company does not have an established asbestos bankruptcy trust. Unlike certain asbestos product manufacturers that reorganized under Chapter 11 bankruptcy and created Section 524(g) trust funds, BNSF has remained a solvent operating company and has continued to resolve asbestos claims through traditional civil litigation.

According to asbestos litigation records, claims against BNSF and its predecessor railroads have been filed in federal and state courts across the United States. Plaintiffs alleged negligence and violations of workplace safety standards under FELA, which requires that a plaintiff demonstrate that the railroad’s negligence — however slight — contributed to the plaintiff’s injury. Court filings document that BNSF has been named as a defendant in mesothelioma, asbestosis, and lung cancer cases arising from employment across its predecessor rail networks.

Because BNSF is a solvent defendant without a trust fund, individuals with claims related to exposure during BNSF or predecessor railroad employment would pursue compensation through direct litigation rather than a trust fund claim submission process. The statute of limitations applicable to FELA claims is three years from the date the plaintiff knew or should have known of the diagnosis and its connection to railroad work — a standard that has been addressed extensively in railroad asbestos case law.

It should also be noted that in many railroad asbestos cases, multiple defendants are involved. Third-party manufacturers of asbestos-containing locomotive components, insulation materials, and gaskets — some of which have established bankruptcy trusts — may also be named alongside BNSF in litigation arising from the same exposure history.

Former railroad workers who were employed by BNSF or its predecessor companies — including Burlington Northern, the Atchison, Topeka and Santa Fe, the Great Northern, the Northern Pacific, the Chicago, Burlington and Quincy, or the Spokane, Portland and Seattle — and who have been diagnosed with mesothelioma, asbestosis, pleural disease, or asbestos-related lung cancer should be aware of the following:

  • No BNSF asbestos trust fund exists. Claims must be pursued through direct civil litigation, typically under FELA.
  • Multiple defendants may apply. Manufacturers of specific asbestos-containing products used in railroad settings may have established trust funds that can be accessed separately from any FELA claim.
  • Employment records matter. Documenting job title, work location, and approximate dates of employment with predecessor railroads is important to establishing exposure history.
  • Time limits apply. FELA’s three-year statute of limitations runs from the point of diagnosis and knowledge of its occupational connection; early consultation with experienced asbestos litigation counsel is advisable.
  • Family members may also have claims. In some cases, take-home asbestos exposure — carried on work clothing — has formed the basis for separate claims by household members.

Attorneys handling railroad asbestos cases typically work on a contingency fee basis, meaning no upfront payment is required. Workers and families researching exposure history are encouraged to gather employment records, union membership documentation, and any available medical records prior to consultation.
