Nice to see Automatic Train Operation reinstated between Stamford Brook and Ravenscourt Park a mere 63 years after it was first introduced. For those that don't know a trial installation of the ATO system that would eventually be installed on the Victoria Line, was brought into use between...

Perhaps the opening post is referring the Sunday night 0019, which of course is technically in the early hours of Monday morning.

My understanding is that the policy adopted after the Moorgate accident was not the blanket adoption of a single yellow aspect on the last stop signal before a terminal platform. Rather it was that the last stop signal before the terminal platform should display the most restrictive proceed...

Correct, but possibly only while the eastbound platform is closed. The CBTC area is due to be extended to Stamford Brook in the near future, and I believe this is currently expected to take place in mid June, between the closures of the eastbound and westbound platforms. Thus, by the time the...

Remember also that a reduced service frequency is virtually unavoidable with this sort of closure as one of the two main depots on the line becomes inaccessible, which in turn places a limit on the number of trains available to provide services on the remainder of the line.

I suspect this page is at present showing the Saturday timetable for this (current) weekend (31st May/1st June 2025), where the Piccadilly line is providing an enhanced service between Rayners Lane and Uxbridge because of engineering work on the Metropolitan line.

What nobody has mentioned so far is what the actual engineering work is. It is the commissioning of new signalling on the Metropolitan line between Finchley Road, through Wembley Park to Preston Road. The nature of modern signalling systems is heavily software dependent, and so in the first...

I have it at the back of my mind that when the Penmanshiel Tunnel collapsed in 1979, blocking the East Coast Main Line, BR were able to construct a short section of new line bypassing the tunnel without any fresh statutory authority, because the new alignment fell wholly within the limits of...

The Underground has never officially tried to get the car numbering to include the stock type as part of the number. Remember that the car numbering schemes also include the Sub-Surface fleets used on the Metropolitan, Circle, Hammersmith & City and District lines and these stock types have...

When London Transport was first formed it was by no means obvious how services on the sub-surface network should be organised. Various different service patterns were tried over the following few years, including I believe a peak hours only Uxbridge to Barking service via the Met which I think...

This 1914 update to the map ( https://maps.nls.uk/view/103313324 ) shows that the centre platforms are the terminal platforms. I would therefore suggest the change in arrangements was made either in connection with electrification of the line in 1905 or with the resignalling which followed...

Except that Whitechapel closed last March. In fact as a consequence of the same stage of the 4LM resignalling scheme the Metropolitan Line Signalling Control Centre at Baker Street is now reduced to only having one signaller on duty at any one time. Other London Underground signal boxes that...

The following file shows a series of diagrams that the depict the alterations carried ou in the Wood Lane/White City area when Wood Lane closed and White City opened. Wood Lane / White City alterations 1947/48/49. (PDF)

The ability to reverse south to north in platform 3 was removed in 2010 when platforms 1 and 4 were extended at their north ends to accommodate then new longer S stock. After the extension there wasn't room for two separate crossovers (12 & 13) so the ability to reverse in 3 was lost. This PDF...
