hi
just wondering the reason as to why the central is in tube tunnel between leytonstone and newbury park even though it is now out of central london and has also been out of tunnel for leytonstone? also is the 92 stock due for refurb soon? was up in london last week and they were sadly not in a very good state for a newish tube stock.

The section from Leyton to Loughton was built in the 1850s as a "conventional" railway when the area was still relatively rural. It was not taken over by London Underground until the 1940s. The tunnel between Leytonstone and Newbury Park on the other hand was built specifically for LU in the 1940s. By this time the area was too built-up to allow another railway on the surface.

Apart from the section in tunnel all of the lines to Epping/Ongar and the loop were part of the main line (GER/LNER). The tunnels could not be built under private property because of the legal problems involved so most of the tunnels are beneath the Eastern Avenue (A12). As the alternative 'cut and cover' method would be too disruptive and the tunnels were only required to take tube stock tube tunnels were bored.

The loop originally continued south from Newbury park to join the main line where Ilford car sheds are now. Plessey's electronics factory was also near the junction. The tunnels had been finished by the start of WW2 but lines had not been laid so the tunnels were used as a factory by Plesseys.

While we're on the subject, I have a question about the tunnels at Rebridge (hope no-one minds). Between the two running lines there is a third tunnel, the same bore as the other two. What was this tunnel intended for, as it is only connected to the others via the cross-passages? |

When did the Government decide they could build a tunnel without compensating the owners of the land above then?

I'm not sure but it could be part of the ventilation system, it's more than 20 years since I worked in that area and I really can't remember. |

out of curiosity why did lu decide to build the tunnel to create the loop. was it a traffic easing measure? The LNER suburban train system out of Liverpool Street was grossly over-loaded. The government made cheap loan money available to extend the Central from its existing terminus at Liverpool Street to Stratford and onwards to take over the Epping/Ongar line and what was then called the Fairlop Loop. The idea was to divert traffic away from the mainline Liverpool Street station. |

Redbridge station was built cut-and cover. There was never any plans for an extra track AFAIK

It's one reason why the A12 is such a slow route out of Lonodn. The tunnels are so close to the surface that they can't grade separate the junctions. The A13 is a much better route although as discussed in a previous thread the 40 mph speed limit may be frustrating.
