One of the key factors with rail work and on-track maintenance is time. With schedules set for commuter traffic flow and other rail activities, having time for things like test pits, bore holes, and daylighting is generally placed within strict deadlines so as not to disrupt daily operations.
On top of the usual standards for excavation safety in proximity to underground utilities, there’s also specialized training and certification required to mitigate specific hazards associated with rail work.
Having crews that are highly trained and experienced with the access restrictions, work environment, and tight deadlines, is pivotal to a cost-effective excavation project on rail. It’s also important to have specialized equipment for on-rail construction and maintenance to keep projects ahead of schedule.
