Hi all,
What's the reason for the long wooden supports on both side of the outside live rail eastbound at Gloucester Road - they've been there for as long as I can remember so don't seem to be any sort of emergency work.
Also, what's the reason for the starting signal there only clearing when the train just about becomes visable round the corner either from Earl's Court or the Circle Line - it's a semi automatic signal, but there's not a junction or anything after it is there? Could it possibly be a hangover from the double tracks years ago?
Fanks!

Though at much older sites such as Ealing Common it is possible to have [on the westbound platform] the WB Starter clear and the Shunt to the depot! |

Those wooden guards are at all locations where there is a platform on the both sides (weather the platform is in use or not), it protects a person from touching the positive rail if they stepped or fell off the platorm as the wood is slightly higher than the current rail. |

that signal on the e/b is not approached controlled it will clear normally if in push button mode but when the machine for the junction is in any other mode the lever operation circuit makes it approached controlled it clears after train has passed ee204 just before the platform
all the signals on the w/b work in t/d mode (auto) or push mode (manual) theres no programme machine for the w/b

If you are saying that you can have WM22 clear and WM6 I don't think so, the mechanical locking will prevent that in the first instance, however, you can have WM22 westbound starter off and WM7 eastbound platform shunt to depot. Interestingly there is a two track overlap on WM5/7, H & HH tracks as I recall and it is the second of these that is the replacing track, the first track being about a car's length and including 12A, 11B points. |

Nope! You can have 22s and 6s off at the same time! The replacing block joint is some way west of the station (it makes putting overlength trains to depot fairly simple!)  |
