not working any signalling quite yet ! Be quite some time before it takes over from Edgware Road too! I can confirm however that the third photograph is accurate and we all signal on our backs. My own profile picture has been digitally altered to prevent the membership from getting vertigo. |

My own profile picture has been digitally altered to prevent the membership from getting vertigo. Has a date been set for the closing of Edgware Road cabin ? Back in 1963 I was Railway Operating Apprentice at the cabin working 06:00 to 14:00 or 14:00 to 22:00. |

Personally I anticipate spending at least another six months there, but we will see how SMA 0.5 goes in a fortnight. |

Apparently a survey train. Simon Mentioned in our S Stock thread: I was passing Upton Park on C2C this morning and saw an S Stock heading Eastbound with some HiVis wearing people on board, I then saw at the back of a train some weird yellow contraption attached to the train (Or maybe I had heat stroke). It was a large yellow metal looking thing about the size of the coupling but slightly above it with a long pole going up to the top of the drivers side of the font LED display. Does anyone know what this is? I can draw a diagram if it sounds too strange to get an answer. S7 21348 was the cab fitted:  Edit to add, are the equipments now fitted to an S8? |

Car number in the Finchley Road picture is 21009 which is an S8.

Pretty sure 21009 falls witin S8 + De-icer. I'm fairly sure it berthed fully when I saw it at Rayners Lane on Sunday.

It is probably worth mentioning that the launch of the new 'Digital Railway' has been delayed... Hammersmith's N frame is still going strong.

That’s a bit quick you trying to catch the lever on the ball catch
You never do it that quick at Edgware Road with all the Surelocks

Which points at Edgware Rd are Surelocks?

Jack Thanks for the update what was the reason for the change. 1. still more testing to do 2. No one brave enough to change over to the new system. Re your frame test is there a time to do this i.e. before the current comes on or is it the signaller's decision and is it laid down in what order. TIA |

When they were style 63 point machines they used to fail regular

Praed street junction think it’s 26 and 27 Correct. They are painfully slow compared to the rest of the station pointwork. Although they're still quicker than Hammersmith since the CBTC enabling works. 10pts in particular are painfully slow with the addition of around a mile of cabling between the frame and the points. They used to be lovely! Jack Thanks for the update what was the reason for the change. 1. still more testing to do 2. No one brave enough to change over to the new system. Re your frame test is there a time to do this i.e. before the current comes on or is it the signaller's decision and is it laid down in what order. TIA A little more testing and tweaking is required before the switch over takes place as I understand it. There's very much a desire to implement it 'properly', thus the slightly different approach from previous resignalling projects, which will hopefully lead to a robust installation for the future. It is worth mentioning that as of last Sunday (20/05) the SCC is now 'fully staffed' ahead of SMA0.5, with the first signalling staff moving in and joining the service controllers, service managers, line information specialists and technical and fleet staff. With regards to frame tests, they are carried out every morning just after traction current comes on (as a signaller we have no way to be certain that all engineering staff are definitely clear of the track until then, though in reality if there is an overrun we will find out much earlier). The actual test itself is at the signaller's discretion - as long as everything is tested out then it doesn't matter what order it is carried out in. At Hammersmith I generally work left to right along the frame as it is most efficient in terms of building up routes and minimising unnecessary lever throws and places you at the right place to signal the first train movements out of the sidings. Conversely, at Edgware Road I work right to left - here it is solely down to the fact that the first service train comes from Hammersmith, so I want to make sure I have everything checked out before the first train enters my area of control - I don't want it to see any 'wrong' routes, or to end up stalled between Paddington and myself because of a failure. We also test out the emergency release lever functionality to ensure there's no issues there, which would involve bringing all trains to a stand if there were any approaching my area. All that said... different signallers will do things differently, and that's absolutely fine. The weekend of 24/25th June has been given as the replacement target 'opening'. Thanks , as always I await developments . So do I! 🤣 |

Thanks I was thinking that LU would have a procedure knowing how they seem to like having them but all down to the signaller. I hope you fill the forms in for taking a release!!

Good job its not like how it was where the release was on a screw and the counters actually worked

What is the maximum speed that CBTC for 4LM will be able to run trains at?
I only ask because every article that refers to it cites the critical speed as 50 mph which is slower than the MET S8's manage under conventional signalling.

it could run trains up to any speed you like in theory I'm sure it will be whatever the S7's max out at (well nearly max out)

Post by goldenarrow on May 30, 2018 11:59:27 GMT
Are the S7's still limited to 47.5 mph to mitigate against the compromise to signal braking distances due to the spacing of signals?

What is the maximum speed that CBTC for 4LM will be able to run trains at? In outer areas I’m expecting 100kph, eg. beyond Barking. Are the S7's still limited to 47.5 mph to mitigate against the compromise to signal braking distances due to the spacing of signals? In weak-field areas they are at present, in non- weak-field areas around 42mph. |

I think I am right in saying that today will see the first engineering train operate on the network under CBTC signalling, albeit still in a test area. T640, formed L18+L17, ran to Hammersmith sidings yesterday ahead of test operations today. The two yellow boxes either side of the 'M' door are the CBTC antennae. clickyAlso of note, today sees the largest test area of CBTC to date - Edgware Road (OP) signal cabin has been 'switched out' for the first time, as has partial control of Baker Street SCC. Trains will be cycling through the entirety of SMA 0.5, 1 and 2, from Hammersmith/Paddington (Circle) to Euston Square, but not Finchley Road to Baker Street. |
