the GSM-R infrastructure: this number includes both ordinary and high speed lines, as well as more than of tunnels. Roaming agreements with other Italian mobile operators allow coverage of lines not directly served by GSM-R. Roaming agreements have also been set up with French and Swiss railway companies and it is planned to extend them to other countries. Netherlands In the Netherlands, there is coverage on all the lines and the old system called Telerail was abandoned in favour of GSM-R in 2006. Norway In Norway, the GSM-R network was opened on all lines on 1 January 2007, replacing the older Scanet network. UK Mainland The implementation of over of GSM-R enabled railway, intended to replace both its legacy VHF 205 MHz National Radio Network (NRN) and UHF 450 MHz suburban Cab Secure Radio (CSR) systems is now complete as of January 2016. By October 2013, both the West Coast Main Line (WCML) and East Coast Main Line (ECML) to Scotland were covered by GSM-R and UK train operator Northern Rail had implemented GSM-R on a significant number of routes in North and North-West of England. In spring 2013, the Association of Train Operating Companies' website GSM-R Online announced that the implementation of the Southern half of the UK GSM-R system was complete as the final CA15 section had gone live (The UK GSM-R Project implementation divided the Mainland North and South of a map-line running from the Severn in the West to the Wash on the East coast). Infrastructure and installation work continued North of this division. Britain's GSM-R network was originally expected to be fully operational by 2013, but due to slippage in equipment fitting a later date became more likely. However, a Rail Safety & Standards Board document indicated that the UK's Telecommunications Regulator, Ofcom, was to withdraw the existing NRN 205 MHz frequencies by 2015. Britain's GSM-R network's cost was originally put at £1.2 billion. That cost though did not include the WCML. The Cambrian Line ERTMS – Pwllheli to Harlech Rehearsal commenced on 13 February 2010 and successfully finished on 18 February 2010. The driver familiarisation and practical handling stage of the Rehearsal had provided an excellent opportunity to monitor the use of GSM-R voice in operation on this route. The first train departed Pwllheli at 08:53hrs in ERTMS Level 2 Operation with GSM-R voice being used as the only means of communication between the
