Road risk affects every sector of the industry where people drive for work. Network Rail alone uses some 5,000 plus road vehicles, and its contractors considerably more. They are used to move plant and materials to work sites, and staff to and from home every day. Both passenger (TOC) and freight (FOC) train operators use taxis to get staff to the places they need to be. TOCs also use rail replacement buses to move passengers when services are disrupted - and taxis to ferry some less able passengers to their nearest accessible station.
