RailPros began a relationship with the Washington Metropolitan Area Transit Authority (WMATA) by providing track inspection services. The exceptional work performed by the RailPros team prompted WMATA to extend the contract and request additional track inspectors as well as administration support. Later, when WMATA required flagging services, the organization chose RailPros to provide Advanced Mobile Flagging (AMF) for track workers and maintenance activities in close proximity to the railroad right-of-way throughout their system.
