Just looking at some old pictures of South Ruislip and West Ruislip and noticed the platforms had a nice 1950's looking curved conrete canopy instead of the flimsy looking tin roof's they have now. Does anyone here know why they were replaced?  |

These were the "butterfly" canopies and an integral part of the new branch's design by the GWR. I believe "concrete cancer" or similar got the better of them in the 1980s, but it's a real shame replicas weren't commissioned as they were the only features of architectural interest on these island platforms and that which replaced them are bland to say the least.

I remember when the Holden-esque roundels at these stations were replaced ones with a white background in the 70s. It was very upsetting to my primary school persona at the time   |

Presumably yes, BO. It must be remembered that reinforced concrete is a cheap and quick method of construction, and that (IIRC) TfL are the owners of the vast majority of the earliest structures in Britain to be made in such a way.
Its the action of water and air on the rebars thats to blame a lot of the time. The rebars rust, expanding in the process. This causes the concrete above to crack and fall off, which in turn compromises the structural integrity of the structure, increasing internal forces, which in turn lead to continued failure.

I understand that to have been pretty much the case. 'Becoming structurally unsound' would be a good description of the state of the canopies, with concrete spalling from the undersides of them and much rusting of the reinforcement. Unfortunately, money was in short supply when the replacement work needed to be carried out, hence the rather 'basic' replacement canopies. |

Thanks for that Stig, the second West Ruislip pic looks as if it was taken when still under construction.

TfL kinda ruined the central line as its now no heritage train territory, they should have refurbished the 62ts majorly (like what they did with the 73ts) and kept the tripcock system! Imagine the ltm's 38ts from West Ruislip - Epping, around the loop and back, or Cravens' 62ts! Or maybe thats just me wanting things Im not old enough to have gone on or remember

I think you've got it in one. The Underground is not a heritage museum, despite what many people seem to want on this forum. It's a means for people to get from A to B, and the majority of the ordinary passengers couldn't really give two hoots what the station canopies look like, what sort of stock they have etc.
As someone who uses the Central Line at the east end of it every day, give me 1992 stock (and yes it's nowhere near perfect), the new signalling system (which by and large behaves itself) and stations how we have them now (my locals Leyton and Leytonstone are perfectly acceptable, and the refurb at Leyton was decently done).

The problem is that at the time of the Central Line project the trains were thirty years old and to a basic design which was much older, and the majority of the signalling was life expired. It was a very good opportunity to maximise the benefits of renewing both the rolling stock and signalling at the same time. At the time the 1973 Stock came up for refurbishment it was only twenty years old with a signalling system that generally was slightly younger, thus refurbishment was the more viable option. |

I think the Central line platforms in these parts look fine. The ones at South Ruislip certainly look better than the adjacent national rail platforms. They look hideous. It really is a bad advert for Chiltern Railways.

I dont think Chiltern realy care about South or West Ruislip, they know that the amount of UndergrounD services in the area outweigh the use of Chiltern into London. In the morning peak you'll only see a few commuters over on those platforms! It's got so bad people at my school think you get the Central Line to get to Glasgow or the Metropoiltan to get to Brighton!

Whats the incentive to refurb the Chiltern platforms at the ruislips?? When HS2 goes through there (as it undoubtedly will) the entire formation is more than likely to see massive changes with the widening straightening and reconstruction. 25 years from now it'll be unrecogniseable for the second time!  |
