Asbestos in Railroad
Asbestos in Railroad
If you worked in a railroad yard or on the crew of a rail car, you were probably exposed to asbestos. It is important that you learn as much as possible about the material and about asbestos disease.
Railroads: Asbestos On the Line
Steam locomotives and some diesels were insulated with asbestos. Insulation was used around boxcars and cabooses, refrigeration units, pipes, and steam and hot water lines. One frequently–used high–temperature asbestos pipe insulation, Johns–Manville Therma–Wrap, consisted of amosite asbestos fibers enclosed in a wire mesh, and surrounded by an asbestos cloth jacket. Asbestos was also common in packing, rope, cement, gaskets, and in heavy–duty floor tiles for passenger cars.
Asbestos Insulation
Pipefitters and workers who installed insulation, removed it, or inspected it were heavily exposed to asbestos. When locomotives were inspected, asbestos insulation was stripped off the boilers. During this process, and when the asbestos was reapplied, asbestos dust often escaped into the shop or repair facility. As a result, others working in the vicinity were also exposed to asbestos–contaminated air.
Asbestos in Brakes and Clutches
Railroad brakes and clutches provided another source of contamination. Because asbestos is heat–resistant and strong, it was often used in brake and clutch linings. Railroad mechanics were routinely exposed to asbestos, as were those who breathed asbestos–laden air nearby.

The Program is built on the existing multidisciplinary team collaborating on mesothelioma research and treatment: Brigham and Women’s Hospital - Division of Thoracic Surgery and the Departments of Anesthesiology, Dermatology, Pathology and Radiology; Dana-Farber Cancer Institute - Departments of Medical and Radiation Oncology; Department of Society, Human Development, and Health; Pain and Palliative Care Service; and the Thoracic Oncology Program; Harvard School of Public Health - Departments of Environmental Health and Cancer Cell Biology; Massachusetts General Hospital – Biostatistics Center.
The research interests of the program investigators span the range from basic MPM biology and target discovery (growth control, over-expressed genes, and expression of SV40 large T antigen) to clinical treatment of MPM (diagnosis, pathology, surgical techniques, improvements in treatment, outcome, and patterns of recurrence). Collaborations among the investigators have resulted in fourteen joint publications since 1993, as well as publications from the individual groups.
The success of our new program will be based on the concept of a multidisciplinary team. Ultimately, the objective of the program is to offer potentially curative therapy to patients with mesothelioma. Our success in the fight against MPM will be the direct result of the hard work and effort of dedicated professionals.
