The first section of the long awaited SSR resignalling, Thales CBTC Signal Migration Area 0.5 from Hammersmith-Latimer Road goes live with the first trains tomorrow morning. Hammersmith signal cabin (OZ) will close after the last train tonight. >insert tears from bluegoblin7< A normal weekend timetable will operate but trains will initially run empty from Paddington-Hammersmith until passenger approval is gained, hopefully sometime on Sunday. The contract was signed on 3 August 2015: http://www.railwaygazette.com/news/...-sub-surface-lines-resignalling-contract.html Maximum line speed will be increased to 50mph in this section, from the previous 35-40mph. Restrictions obviously remain on certain infrastructure and pointwork.
