Following on from the thread on the signalling Diagram for Turnham Green I thought the following diagram might be of interest as well Cromwell Road (1.6MB) I should warn you it is a very big file but it covers the area from west of Earls Court to High St Kensington and east of South Kensington as it was in 1957. Paragraph 1 of the associated supplement to Traffic Circular says |

A superb map, Harsig, Thank you!
Incredible how much has changed since then!

You need to cut and paste the link, and then it should work |

Alternatively you might try Cromwell Road Alternate (1.6MB) Every time I click on the link in my original post I get diverted to this one so perhaps its your firewall that is preventing you from accessing the file. |

I've downloaded it using GetRight (a download manager) - works like a charm (a hint to those who are on the slow or unreliable connections  . |

I managed to get it too. It's certainly quite a different layout than now, although the extra crossovers east of Earls Court on the east side of the w/b island would be a godsend to have on the rougher days of disruption |

Obviously we can still go into platform 4 coming from the city, but not to platform 3 from HSK! The reason I ask is because I noticed the other day that signal REC36 ab (on the wall of triangle as you drop down the dip) still has a route indicator showing the move from that line to platform 3! |

Not an exact answer but Traffic Circular 14/66, in operation for the week commencing Saturday 16th April 1966, says so it seems the answer is early 1966. |

Why was the crossover removed? Surely there is sense in retaining the ability to run the entire service from either side of the w/b island, or to provide a place to path trains in case of a breakdown in the platform road.
Then again, if the existing IMR at EC was in place in 1966, perhaps it won't be so had to restore the crossover...

Unfortunately the 1966 alterations were in connection with the commissioning of the current IMR. You'll notice that the other crossover mentioned in the traffic circular extract as having been removed was the one which gave access from the Wimbledon Branch to the outside of the eastbound island platform. I had heard a rumour that the simplification of the track layout was connected with the introduction of programme machine control. |

Considering that in the 60s, LT wasn't high on the priorities list of the Minister of Transport, I'm surprised that the amount of flexibility is still relatively good! Too bad that resignalling the site now as part of the District closures would be completely impossible to do  |

I had heard a rumour recently (you hear at least 2 every day working on LUL!), that the crossovers removed both East and Westbound are to be restored at some point in the distant future. If they ever are - you read it here first !! |

If they ever are - you read it here first !! Yup, I've heard that too - and I believe it does fall in with the SSL upgrade plans. Personally I think it will happen - we need more flexibility round Earls Court and this must help. I'm sure that with the benefit of hindsight it's accepted that the removal of the crossovers to both the east and west of the station was a mistake. |

The only reason those crossovers were removed was to eliminate the diamond flat crossings or so I was once told. This was called rationalisation at the time of the programme machine installation. That was also the excuse given when Acton Town was re-signalled. "To confine conflicting moves to the bare minimum"

So where exactly will the crossovers be put back?

So where exactly will the crossovers be put back? As i understand- from WB line ex-HSt KENSINGTON into platform3 from EB line ex-WEST BROMPTON into platform1 |

I wonder if modern computer based interlockings are noticeably slower when controlling complicated areas as opposed to simple areas?

i wouldnt hold your breath at the earliest when the district line gets resignalled and that aint gonna happen till at least 2012 even though we heard at work its not gonna be to 2016 now but who knows earls court is a complex site and tom is right programme machines are simple in there principles but the design of the circuits is something else as im sure theres a few people on here will agree with me, the only saving grace with them is that only a few signal ops know how the sites should work properly so we only get a few nasty jobs on them
