Who Are We

Capital Railroad Contracting proudly announced the acquisition of Koppers Railroad Structures, effective August 29, 2025. With this acquisition, Capital Railroad Contracting continues its commitment to growth and provides high-quality railroad construction and maintenance/repair services across the country. 

Koppers Railroad Structures (formerly Osmose Railroad Services) was formed in 1954, in response to the Gulf, Mobile & Ohio Railroad’s request to help “extend the life” of their timber bridges. After spending the first decade providing preservative treatment of timber bridges in-place, the company was asked to help repair them too. In 1965, we began posting piling, changing caps and a little later, replacing stringers. We are now one of the largest timber bridge service/solution providers in North America. 

As concrete, stone and masonry structures started to crack due to age and traffic patterns, again, we were asked to solve these problems too. Thus began our pioneering service of epoxy injection to “weld” broken pieces together. This expansion continued into a full-service concrete repair including the use of special polymer mixtures to speed repairs in traffic sensitive zones. Over time, greater engineering expertise was needed and that part of our support team also began to expand.
