Incidentally in the third photo you can just about see the route set through Aylesbury and towards Aylesbury Vale Parkway which, I think, UKTM mentioned somewhere. These routes were set by ARS and demonstrates how fallible the real system is: not only was it poor regulation but it would have resulted in a Mexican stand-off outside Aylesbury Vale Parkway. The signaller put a reminder on the signal outside Aylesbury (ME383) to prevent ARS doing it again once the routes had timed out. IIRC both trains ended up being delayed by a few minutes.

Thanks for these photos - especially number 2, which neatly answers my question about the wall siding

" said:If I recall correctly, the patrolman gets a key that fits in a trackside box. So if they're patrolling the Up Slow, they phone the box for permission and a release and then use the key. That section of line then gets marked on the screen as unavailable, with automatic reminders on the signals reading into it. When they finish the patrol, they go to the box at the other end of the section and release the lockout. It's sort of an automated possession system. Log in to reply |

What does the Patrolling Lockout thingy do? On our ones at TBASC from Preston Park to Balcombe Tunnel Junction, they work by locking out the bi-direction signalling (simbids in our case) when they are activated. We press a button for the section concerned which then flashes, this is idicated to the patrolman in their trackside location cabinet. They then turn their key in the lockout device. Our idication then goes steady as does theirs. Then that's our bi-ditectional signalling locked out until they've either walked throughh the section or have returned back to the same one.

Thanks Clive. I wonder if, in this case, it's used for patrolling Saunderton Tunnel? Found this if it's of any interest to anyone? http://www.rgsonline.co.uk/Railway_Group_Standards/Traffic%20Operation%20and%20Management/Railway%20Group%20Standards/GKRT0030%20Iss%201.pdf Log in to reply |

Just out of interest did the group also visit Chiltern Control? I do recall seeing mention of the possibility of visiting more than one operational location at the same site.

The patrolmans lockouts only lock te wrong direction moves. I know they used to be a nightmare to test every year as the S&T did not have keys to it. AndrewG, Chiltern Control is in a glorified portakabin opposite Banbury South Signal Box, not at Marylebone. Log in to reply The following users said thank you: Andrew G, John |

What you will actually see on Marylebone is the direction of flow indicators turn red for the routes than can not now be set. The whole ethos is not to shut the line, rather to allow the Patrolman to walk from one end of the section to the other without a train coming up behind him. Normal direction traffic will continue to flow.

B)Oh, and: a car ice scraper;Initially thought to be something to do with toast (maybe a mass butterer), then thought to be a tile grouting tool. But the ice scraper sounds more plausible, if a little ordinary! :) For the benefit of all (both those perhaps wondering, and those who got one), it's this exact one - but with the added Chiltern Railways branding in the print area.
