Title: ^20m railway upgrade includes signalling. (Western Gazette 08/04/2010) Post by: JayMac on April 08, 2011, 19:59:17 From the Western Gazette (http://www.thisissomerset.co.uk/news/163-20m-rail-upgrade-includes-signalling/article-3426489-detail/article.html):
Quote The signals on the railway running between south Wiltshire, Dorset and south Somerset is being upgraded as part of a ^20 million scheme. Network Rail said some of the infrastructure on the 90-mile route between Salisbury and Exeter dated back to the 1960s and was coming to the end of its life. The upgrade is expected to improve the reliability of the system and extend its lifespan for another 35 years. Work will start this autumn. Title: Re: ^20m railway upgrade includes signaling.

Sussex, Kent) IP (Investment Projects) area of S & E (signaling and el;electrification) this is being done by the the IP S&E LNW (London Northwester & Western) team based in Swindon. The reason why IP S&E WSK are not involved is they have major schemes in East Kent, South Coast, Victoria (relocking) and number of other relocking or resignalling schems also part of the team who were doing London Bridge have transfered to Thameslink Program
A busy time in S & E projects Title: Re: ^20m railway upgrade includes signalling. (Western Gazette 08/04/2010) Post by: JayMac on April 08, 2011, 21:31:08 Umm....
relocking? Title: Re: ^20m railway upgrade includes signalling. (Western Gazette 08/04/2010) Post by: signalandtelegraph on April 09, 2011, 06:07:11 Umm.... relocking?

Substantial alterations, to track layout for example, that necessitates major changes to existing signalling control circuitry (interlocking) = relock This can also mean that the existing track layouts remain unaltered but the number of signal boxes is reduced, the control for several boxes being put into one box the "Absolute Block Working" principle is kept but instead of a man / woman manually forwarding and accepting trains this is being done by "computers" at locations which use track circuits or axel counters, auto signals etc to monitor trains and forward and receive them from one block to the next its not a full resignalling Title: Re: ^20m railway upgrade includes signalling.

It would seem that the present signalling system will be replaced and controlled by a work station at Basingstoke. This link shows the document which mentions it, or just browse salisbury exeter signalling in the Network Rail site http://www.networkrail.co.uk/browse%20documents/network%20code/network%20change/current%20proposals/wessex/ncg12010wesx006%20salisbury%20to%20exeter%20signalling%20renewal/a%20ncg12010wes006%20notification.pdf Edited to fix link. bignosemac Title: Re: ^20m railway upgrade includes signalling.
