Documented Asbestos Evidence

The records below are verified, state-documented asbestos removals at this facility. Each entry represents a regulated abatement project where the Missouri Department of Natural Resources (Missouri DNR) was notified under federal NESHAP rules, the work was logged, and the asbestos-containing material was confirmed and removed under regulated conditions. These are not allegations or estimates — they are paper records tying documented asbestos-containing material to this specific site.

No Missouri DNR NESHAP abatement notifications have been identified for this facility in current public records. Per the framing above, absence of state-agency documentation should not be read as absence of asbestos — only as absence of a formal, regulated abatement event meeting reporting thresholds. Workers who recall encountering pipe insulation, block insulation, gaskets, or other asbestos-era construction materials at this facility may still have viable claims regardless of whether a state record exists.

Who May Have Been Exposed at Missouri Pacific Railroad Missouri

Major St. Louis Facilities

The Missouri Pacific General Car Shops

Freight car and passenger car inspection, repair, and rebuild work. Carmen, machinists, pipefitters, and laborers working under Heat and Frost Insulators Local 1 and Plumbers and Pipefitters UA Local 562 worked directly with asbestos-containing insulation from, Armstrong, and calcium silicate insulation, asbestos gaskets from gaskets and packing and, packing materials, and friction products daily. The Missouri Pacific Locomotive Shops

Steam locomotive repair involved enormous quantities of boiler insulation and pipe lagging—pipe covering, calcium silicate insulation, pipe and block insulation, and products. Diesel locomotive maintenance involved gaskets and packing and asbestos gaskets, asbestos brake components, and asbestos-insulated cab panels used into the 1980s. The Valley Park Diesel Shop

Heavy diesel locomotive maintenance southwest of St. Louis, including engine overhauls, brake system repairs with asbestos components, and work on cab insulation materials. The St. Louis Terminal Facilities

Hostlers, machinists, and maintenance workers employed under Heat and Frost Insulators Local 1 encountered asbestos brake dust from deteriorating linings, gasket debris from gaskets and packing and products, and insulation from and Armstrong daily. Market Street Office Building and Headquarters

Administrative buildings constructed with spray-applied asbestos fireproofing, joint compound floor tiles, wallboard drywall joint compounds, pipe insulation from, Armstrong, and calcium silicate insulation, and Pabco duct insulation—exposing clerical workers, maintenance personnel, and building trades workers over decades.

High-Risk Occupations

Boilermakers

Boilermakers faced the most intense asbestos exposure of any trade at Missouri Pacific. Their work required direct installation, maintenance, and repair of steam boiler systems wrapped in pipe covering, calcium silicate insulation, and pipe and block insulation insulation. Many were members of Boilermakers Local 27. A boilermaker inspecting a steam locomotive stripped off old asbestos lagging—thick, deteriorated material baked in service heat for years. When that blanket was pulled, cut, or broken, it released clouds of fiber. After repairs, the same worker installed new asbestos insulation, cutting pipe covering and insulationFlexboard or calcium silicate insulation blankets and seating new gaskets and packing. Even as steam gave way to diesel, boilermakers remained in high-temperature system maintenance using and Armstrong products. Pipefitters and Steamfitters

Pipefitters working under Plumbers and Pipefitters UA Local 562 worked throughout Missouri Pacific’s infrastructure—locomotive shops, car shops, terminal buildings, office buildings—on steam, water, compressed air, and fuel piping requiring thermal insulation from, Armstrong, calcium silicate insulation. Their daily work included:

  • Cutting pipe covering and insulationFlexboard, calcium silicate insulation, pipe and block insulation, and Armstrong pipe insulation to length
  • Fitting insulation around pipes and fittings
  • Applying and asbestos-containing joint compounds
  • Seating valve packing made of compressed asbestos fiber from gaskets and packing

Valve packing removal was particularly hazardous—old gaskets and packing and competitor packing had to be physically dug out of valve bodies, releasing fine asbestos fiber directly into the worker’s breathing zone. Locomotive Mechanics and Engine Builders

Locomotive mechanics at Missouri Pacific’s St. Louis shops worked on every locomotive system—engines, fuel, compressed air, brakes, and cab construction. This work routinely involved:

  • Replacing asbestos brake shoes and linings on both steam and diesel locomotives, generating heavy brake dust
  • Removing and replacing gaskets and packing and asbestos gaskets during engine overhauls, using wire brushes and scrapers that pulverized gasket material
  • Working inside locomotive cabs insulated with asbestos-containing panels
  • Handling asbestos rope packing in cylinder heads and valve covers

Engine overhauls were the highest-exposure events. Mechanics worked for hours inside engine compartments, scraping old gaskets and installing new ones, in spaces with minimal ventilation. Carmen

Carmen inspected and repaired freight and passenger rolling stock at Missouri Pacific’s car shops. Their exposure came from multiple sources:

  • Brake shoe replacement on freight cars using asbestos friction materials
  • Repair of passenger car heating systems insulated with and Armstrong products
  • Work on passenger car underframes insulated with asbestos materials
  • Incidental exposure from adjacent trade work by insulators, pipefitters, and boilermakers working in the same shop spaces

Machinists

Machinists at Missouri Pacific’s shops worked on precision components of locomotive and car systems. Their asbestos exposure came from:

  • Machining operations on asbestos-containing brake components that generated fine particulate
  • Gasket cutting from gaskets and packing and sheet asbestos stock
  • Work in close proximity to boilermakers and pipefitters performing insulation work
  • Clutch and brake work on shop equipment using asbestos friction materials

Critical Filing Deadline & Next Steps

Missouri law gives mesothelioma and asbestos-disease claimants 5 years from the date of medical diagnosis to file a personal-injury lawsuit (Mo. Rev. Stat. § 516.120). For wrongful-death claims after an asbestos-related death, the filing window is 3 years from the date of death (Mo. Rev. Stat. § 537.100). The two deadlines run on separate tracks — preserving one does not extend the other.

The personal-injury clock runs from diagnosis, not from exposure. Mesothelioma latency is typically 20 to 50 years, so workers exposed in the 1950s–1980s are being diagnosed today.

Practical first steps

  1. Document what you remember. Pay stubs, W-2s, union cards, photographs, coworker names, and dates of employment. The WorkChain widget on this page can save a copy you can email yourself.
  2. Preserve medical records. Pathology reports, biopsy results, imaging, and pulmonary-function tests are central to both civil claims and trust-fund filings.
  3. Identify household members. Spouses who laundered work clothing and children of plant workers are eligible for secondary-exposure claims when diagnosed with an asbestos-related disease.
  4. Speak with an asbestos attorney with Missouri experience. The first conversation is free and confidential. Asbestos trust-fund claims and civil claims run on different tracks — both can be pursued in parallel.

Asbestos-Related Diseases

Asbestos fiber exposure can cause several specific diseases that typically appear decades after the original exposure. The latency period — the gap between exposure and diagnosis — usually runs 20 to 50 years. That's why workers exposed in the 1960s, 1970s, and 1980s are receiving diagnoses today.

Mesothelioma

A rare, aggressive cancer that affects the lining of the lungs (pleural mesothelioma), abdomen (peritoneal), or heart (pericardial). Mesothelioma is almost exclusively caused by asbestos exposure, which is why a mesothelioma diagnosis often points directly to historical workplace exposure. Average latency from first exposure to diagnosis is 30-50 years.

Asbestosis

A chronic, non-cancerous scarring of lung tissue caused by inhaled asbestos fibers. Asbestosis causes progressive shortness of breath, persistent cough, and reduced lung function. It does not improve with treatment, and it is a recognized basis for compensation under most trust schedules and civil claims.

Lung Cancer

Asbestos exposure significantly increases the risk of lung cancer, particularly when combined with a history of smoking. Asbestos-related lung cancer is compensable under the same trust schedules and civil claim avenues as mesothelioma.

Other Recognized Diseases

Pleural plaques, pleural thickening, laryngeal cancer, ovarian cancer, and certain gastrointestinal cancers are also recognized as asbestos-related under various trust schedules and case-law authorities, though eligibility and proof requirements vary by claim type.

If you have any of these diagnoses and you worked at this facility, lived with someone who did, or were exposed in any documented capacity, you may have a claim worth pursuing. Speak with an attorney before assuming you don't qualify.
