A carry through of failures from yesterday night starting with a train at Baker Street at around 21:00, information initially said faulty train but the switched to signal failure. London Bridge then joined the party an hour later with no service south of FInchley Road. London Bridge was sorted within an hour leaving the current situation.
I should stress that this next bit is a hunch, but I believe something that's this serious must be to do with semi-automatic station starting signal BAS/BM2 at Baker Street (Southbound) which gives access to the Bakerloo line via no.3 points. The components that drive those pneumatic point mechanisms feeding into the CBTC system are venerable at best.
First train at 21:27 became NCT Non Communicating Train and was authorised to go into RM Restricted Manual and regained Comms with Neasden further along. At 21:45 a second train became NCT causing a suspension to find the route cause of the issue at first a broken loop was suspected but this was not the case and at 02:33 the VCC was rebooted for the area
London Bridge was a loss of detection on points 5b caused by a known network wide issue of the indicating rod
I don't know what KLM stands for but its a spring clip like a circlip which is used instead of a split pin to stop a pin falling out which attached the indication rod to the rail
I do have pictures but no where to host them
The problem is they break with points bouncing which require lifting and packing and when it will breaks it causes the pin which is holding the indicating rod to the rail to come out and thus failing the points.
Deary me, two forum moderators blatantly using TLAs in flagrant disregard of forum policy on this matter. And by their own admission not even knowing what said TLA is an abbreviation of!
