The Cross London Route Utilisation Strategy (CLRUS) was the second of the route utilisation strategies (RUS) published by Network Rail (NR), in August 2006. It was included in a map published by the Office of Rail Regulation as established in May 2007.
The CLRUS covers mainly orbital railway lines in North London, including the North London line (NLL), the West London line (WLL) and the Gospel Oak to Barking line (GoBLin), but also the South London line (SLL) and, to a lesser extent, Transport for London's East London line (ELL).
