Alco Locomotive Train (American Locomotive Company)

Company History

The American Locomotive Company — widely known as Alco — was one of the most prominent locomotive manufacturers in United States history. Formed in 1901 through the consolidation of several regional locomotive builders, Alco grew into a major industrial force, supplying steam and diesel-electric locomotives to railroads across the country and around the world. At its peak, Alco operated large manufacturing facilities, most notably its celebrated Schenectady, New York plant, which produced thousands of locomotive units over the course of the twentieth century.

Alco competed directly with General Motors’ Electro-Motive Division (EMD) and General Electric throughout the diesel transition era of the 1940s and 1950s. The company introduced a series of well-regarded diesel-electric models, including the RS-series road switchers and the Century series locomotives, which served freight and passenger railroads from coast to coast. Despite its engineering reputation, Alco struggled commercially against its competitors and ceased domestic locomotive production in 1969, though its Canadian subsidiary, Montreal Locomotive Works, continued manufacturing under Alco designs for several additional years.

During the decades of Alco’s most intensive production — roughly the 1940s through the late 1960s — asbestos was a standard industrial material used across American heavy manufacturing. Railroad equipment, with its high-heat operating environments, was considered a particularly appropriate application for asbestos-containing insulation, gaskets, brake components, and fireproofing materials. According to asbestos litigation records, workers who built, maintained, repaired, or rode aboard Alco locomotives were potentially exposed to asbestos-containing materials incorporated into these units during the manufacturing process and subsequent service life. Alco locomotives remained in active service on American railroads well into the 1980s, meaning exposure risk extended significantly beyond the company’s production years.

Asbestos-Containing Products

Alco did not manufacture asbestos as a raw material; rather, the company incorporated asbestos-containing components and materials supplied by third-party manufacturers into its locomotive products, as was standard industry practice during the relevant period. According to asbestos litigation records, plaintiffs alleged that Alco locomotives were built with a variety of asbestos-containing materials throughout the mid-twentieth century.

Court filings document allegations involving the following categories of asbestos-containing materials associated with Alco locomotive units:

Thermal Insulation. Locomotive engine compartments, exhaust systems, and piping required substantial heat insulation. Plaintiffs alleged that Alco locomotives incorporated asbestos-containing pipe insulation, block insulation, and blanket insulation designed to protect workers and components from extreme operating temperatures. Friable insulation of this type, when disturbed during maintenance or repair, is known to release respirable asbestos fibers.

Gaskets and Packing Materials. Diesel-electric locomotive engines contain numerous high-temperature, high-pressure junctions requiring gasket seals. According to asbestos litigation records, Alco locomotives used asbestos-containing gaskets throughout their engine assemblies, including around cylinder heads, exhaust manifolds, turbochargers, and cooling system components. Removal and replacement of these gaskets — routine maintenance tasks performed by railroad shop workers — generated asbestos dust.

Brake Shoes and Friction Components. Railroad braking systems historically relied on asbestos-containing friction materials to withstand the heat generated by stopping heavy rolling stock. Plaintiffs alleged that Alco locomotives and associated rail cars used asbestos-containing brake shoes and related friction components. Brake work performed in railroad repair shops produced airborne asbestos dust that could affect workers across a shop floor.

Electrical Insulation. Alco’s diesel-electric locomotives relied on large electrical systems, including traction motors, generators, and control wiring. Court filings document allegations that asbestos-containing electrical insulation was used in these systems, as asbestos offered both heat resistance and electrical insulating properties valued in industrial applications of the era.

Fireproofing and Deck Materials. The cab interiors and mechanical spaces of Alco locomotives may have incorporated asbestos-containing fireproofing compounds, floor tiles, and deckboard materials, consistent with general industrial construction practices of the 1940s through 1960s. Plaintiffs alleged these materials posed exposure risks during both initial construction and subsequent renovation or repair work.

It should be noted that because Alco ceased domestic production in 1969, many of the locomotives it built remained in service through railroad operators for years or decades afterward. Maintenance, overhaul, and repair of these units — performed by railroad shop workers, carmen, and outside contractors — continued to generate potential asbestos exposure long after Alco’s manufacturing operations ended.

Occupational Exposure

According to asbestos litigation records, a broad range of workers have alleged exposure to asbestos-containing materials in connection with Alco locomotive equipment. These occupational groups include, but are not limited to:

Locomotive Assemblers and Factory Workers. Workers employed at Alco’s manufacturing facilities, particularly the Schenectady plant, were in direct contact with asbestos-containing insulation, gaskets, and other materials during the construction of locomotive units. Plaintiffs alleged that factory conditions during peak production decades involved significant airborne asbestos dust with inadequate protective measures.

Railroad Shop Machinists and Carmen. Workers employed in railroad maintenance and repair facilities — known as roundhouses or back shops — performed overhaul and repair work on Alco locomotives throughout their service lives. Court filings document allegations from machinists, carmen, and pipefitters who worked on Alco units in these environments, often disturbing aged and deteriorating asbestos insulation and gasket materials.

Locomotive Engineers and Firemen. Crew members who operated Alco locomotives over extended careers may have experienced secondary exposure to asbestos-containing materials within locomotive cabs and engine rooms, particularly during periods when insulation or interior components were disturbed or in deteriorated condition.

Boilermakers and Pipefitters. Skilled tradespeople who worked on locomotive piping, exhaust, and heating systems — whether at Alco’s manufacturing plants or in the field at railroad facilities — were identified in asbestos litigation records as an occupational group with potential significant exposure to asbestos-containing insulation and packing materials associated with Alco equipment.

Outside Contractors and Maintenance Vendors. According to asbestos litigation records, workers employed by third-party contractors who performed maintenance, repair, or overhaul work at railroad facilities also alleged exposure to asbestos materials in connection with Alco-manufactured equipment.

The pattern of exposure associated with Alco locomotives reflects a broader reality of the American railroad industry: because locomotives had long operational lifespans, asbestos exposure risk persisted at railroad facilities long after manufacturers had delivered equipment and, in Alco’s case, after the company had ceased domestic production entirely.

Trust Fund / Legal Status

Alco (American Locomotive Company) does not have an active asbestos bankruptcy trust fund. The company ceased domestic locomotive production in 1969 and did not pursue a bankruptcy reorganization that resulted in the establishment of a dedicated asbestos compensation trust of the type created by manufacturers such as Johns-Manville or Owens Corning.

According to asbestos litigation records, claims involving Alco locomotive exposure have historically been pursued through civil litigation in state and federal courts. Plaintiffs in these cases have generally brought claims alleging negligence and failure to warn, contending that Alco incorporated asbestos-containing materials into its products without adequate warnings to workers who would foreseeably encounter those materials during manufacturing, maintenance, and repair activities. Court filings document that defendants in Alco-related cases have included not only allegations against Alco’s corporate successors but also against the manufacturers and suppliers of the asbestos-containing component materials installed in Alco locomotives.

Because no Alco-specific trust fund exists, individuals who believe they sustained asbestos-related injuries connected to Alco locomotive exposure should be aware that their legal options may include:

• Civil litigation against Alco’s corporate successors or related entities, depending on the specific facts of their exposure history and applicable statutes of limitations
• Claims against component manufacturers’ trusts, since many of the companies that supplied asbestos-containing gaskets, insulation, and friction materials to Alco have established bankruptcy trusts — including trusts administered for companies such as Garlock, Flexitallic, and others documented in asbestos court filings
• Railroad-specific legal claims, as workers employed by railroad operators may have additional legal avenues under the Federal Employers’ Liability Act (FELA), which governs injury claims by railroad employees against their employers

Summary

Alco (American Locomotive Company) was a leading American locomotive manufacturer from 1901 until it ceased domestic production in 1969. According to asbestos litigation records, Alco locomotives were built with asbestos-containing insulation, gaskets, brake components, and electrical materials consistent with standard heavy industrial practices of the mid-twentieth century. Workers who built Alco locomotives at manufacturing facilities, as well as those who maintained or repaired Alco units at railroad shops across the country, have alleged asbestos exposure in civil litigation. Because Alco does not have a dedicated asbestos bankruptcy trust fund, individuals researching exposure connected to Alco equipment should consult with an attorney experienced in asbestos litigation to evaluate claims against corporate successors, component manufacturer trusts, or railroad employers under FELA. Documentation of specific job sites, railroad operators, and decades of employment will be important in supporting any such claim.
