This guidance is written for anyone involved in geotechnical or geo-environmental work on Network Rail’s Managed Infrastructure (NRMI). Separate guidance is available for working on the London Underground network. A railway, whilst potentially very hazardous environment, is also a highly regulated and controlled place of work. Unlike working on the highway, where vehicles are a threat to individuals in all accessible locations, rail traffic is confined to the tracks. However, most trains travel much faster than road vehicles, have much longer braking distances and are often not heard until the last minute when approaching. Drivers can do very little to avoid striking plant, tools, or personnel in the path of a train.
