An automatic fog signal on the Underground:  from [ Grace's guide ]An interesting bit of equipment installed on the Underground. The photograph is possibly from around 1906. Automatic detonator layier. Judging by the view - four-track in a concrete cutting, I don't know if this is in the West Kensington / Hammersmith area. There is also a siding in the distance, but I can't make out what the stock is that's stabled on it (it's best to download the picture and zoom in). |

I don't know if it is in that area but the train in the background (Surface stock) seems to be in a siding.

There have been changes in that area over the years, including the addition of the centre siding. Just had a look at Harsig's 1907 Piccadilly line diagram: www.harsig.org/PDF/Piccadilly1931.pdfand it shows a siding east of Hammersmith. It would also match up with the way the track curves in the photo. If that is indeed the location, then I assume that the siding (and its opposite number on the EB side) were lost when the tracks were re-arranged and the middle siding created. I'm assuming that the view is looking to the west, towards Hammersmith. Of course, it could be looking to the east from Hammersmith. |

Not really related, but this photo shows Hammersmith station in 1906 before remodelling. There are only two tracks, the third not yet laid:  from [ Grace's guide ]

This is between Hammersmith and Barons Court. The automatic fog signal is on what was then the EB Picc Line (before the 1932 track rearrangements), looking west towards Hammersmith. The Picc WB is immediately to its left and the District to the left of that. There was one "LER Siding" and one "DR siding" east of Hammersmith in 1931. Note the different style of conductor rails on the Picc, compared to the District.

What is the difference between the two conductor rails? - I can't zoom in close enough to the District to see.

The Picc's conductor rails are of the 'tunnel' type, whereas the DRs are more 'solid and much like today's in the open air.

Sorry if it may be a little off-topic, but would anyone by any chance know where I may be able to collect historical TFL API datasets for research into model development? Your assistance would be of great help, thanks.

Kev918 I think you have left it late and putting in a thread that is 9 years old the link that you have done hopefully no one clicks on it. If you are genuine then you should have started a new thread, but I suspect there is a catch. EVERYONE TAKE NOTE DON'T CLICK ON THE LINK UNLESS YOU ARE SURE.

Has anyone clicked on this link and what happened ? Drico I wonder why you would want to open a link you are either not sure about or not interested in. If the link had been a dodgy one then more than likely a virus or malware would have been downloaded, best to be safe than sorry. |
