This weekend, London Cannon Street to London Bridge is recontrolled to a new workstation at Three Bridges ROC. We’ve spent quite some time updating the London Bridge area map ready for these changes, including even more route indications toward the Low Level platforms, and track and route indications around Cannon Street.

We’ve just made this revised map live earlier than planned so you can see the signalling being commissioned, and also because we have a massive number of fixes and enhancements for you this week! Here’s the list:

• The Hillington West to Gourock and Wemyss Bay map has dozens of new route indications to show where trains have been routed
• The Cricklewood and Hendon to Acton Wells map now has limited signal and route indications. Some of the signals are semaphore signals rather than colour light signals – we’d planned on animating the semaphores so they showed ‘on’ and ‘off’ correctly, but since there are so few semaphore signals that we have status data for, we decided to spend our time elsewhere
• Two missing berths on the up lines on the Nuneaton to Rugeley Trent Valley map have been added, so trains will no longer disappear when crossing between signalling centres
• There are lots of fixes to the Grove Park to Bromley North and Hildenborough map: we’ve fixed the layout at the Marshalling Yard North at Tonbridge, added the MPV depot, AD2063 shunt signal, moved AD117 signal to its correct position, fixed the berth which always shows XXXX at Sevenoaks, removed the ‘Last sent’ berths as they never showed anything, added a route from AD66 in to platform 2 and L322 to Grove Park,
• Some signals on various maps were stuck on green. We can’t see why this is, so we’ve set them back to danger and we’ll monitor the situation. It’s likely that we’ve suffered from an outage to our feeds from Network Rail at some point and are missing data
• On maps with data from the IECCs at Ashford, any berth shared between two signals (a dual berth) never displayed any indication. We’ve put separate berths in and fixed this small problem on several of the maps
• At Selhurst on the London Victoria to East Croydon map, T76 signal was shown in the wrong direction
• We extended the Ingatestone to Hatfield Peverel map to cover up to the fringe with Colchester PSB, including the Braintree and Sudbury branches from Witham and Marks Tey respectively
• The Didcot Parkway to Banbury map had a few issues with position light signals, which we’ve fixed
