The Merseyside Route Utilisation Strategy is a Route Utilisation Strategy published by Network Rail in March 2009. It was the eleventh RUS to be produced. By default, RUSs are established by the Office of Rail Regulation (ORR) unless the latter objects within 60 days. The RUS is included in Network Rail's map as established.
The geographic scope is described as encompassing the Merseyside "journey to work" area. As such it includes all the passenger lines in Strategic Route 21 - Merseyrail, where the main operator on these routes is the similarly named Merseyrail; also considered are adjacent parts of the network: parts of Route 20 (North West Urban), Route 23 (North West Rural) and Route 22 (North Wales and Borders).
The Merseyrail routes can be divided into the following two self-contained subnetworks:
The City Line east of Liverpool Lime Street was explicitly covered in the North West RUS, but this RUS also makes recommendations affecting this line.
As with other RUSs, the Merseyside RUS took into account a number of responses, including the ORR.
