I have been looking at some photographs on Danny Scroggins website of the new NX panels installed in Evesham and Ascot-under-Wychwood boxes as part of the Cotswold line doubling scheme. Does anyone know why they were made as turn-and-push, rather than push-push panels? Also, is the interlocking the old Western Region E10k as well - as the two tended to go together? From an S&T point of view, the circuitry turn-and-push is simpler and requires fewer relays, but this is not the sort of thing that Network Rail tend to care about when designing a new system. Neither box had an existing panel, so I am confused as to why such a panel design would be selected. Log in to reply |

one isa tempted to wonder if it is equipment re-deployed after a big re-signalling scheme elsewhere.

I wondered that when I first heard, but it looks like new stuff to me.

I think it's just one of those cases of "It's the Western Way"

" said:I think it's just one of those cases of "It's the Western Way" I was thinking that but coloured track circuits have been used which isn't the Western Way. Log in to reply |

1980s Western panels like Exeter are push-push. It is to all intents and purposes a modern panel, using the modern symbols etc, but using turn-and-push control. Probably only the designers can explain why. Log in to reply |

How many none-auto signals does the panel control? If there's only a handful, on a small panel with a couple of trains an hour, the simpler circuits of turn-and-push may outweigh the convenience of push-push.

Generally I would agree, however BR seemed to abandon turn-and-push, even on the Western Region, in the 1980s or possibly even earlier. FireFly, if you are reading this, do you have any idea as you seem to be more clued up on current standards than most of us?! Log in to reply |

Reading it, and have no idea. I wonder if the interlockings that these new panels were controlling are old E10k interlockings which have just had minimal alterations to cope with the new signalling. Chard Junction is a good example of this. The pictures of Chard Junction Panel that you can see on Danny Scroggins website are not the original panel. The pictures are of a new panel which was installed when the line at Axminster was doubled in 2009 yet it's still turn and push because chard interlocking was still old E10k. It does however feature coloured track circuits which the original didn't. The 1980's panel complete with black tracks can be seen here FF Log in to reply |

They were mechanical before these alterations Kev. Evesham was token worked to Norton Junction and AB to Moreton. Ascot was AB to Moreton and TCB to Oxford Panel at Wolvercote. Log in to reply |

" said:They were mechanical before these alterations Kev. Strangely even when Ascott-under-Wychwood was a mechanical box, the diagram had coloured track circuits. This is quite unusual for a Western box, even the recent diagram at Truro uses black track circuits. Log in to reply |

The diagram at Truro is a bit of a hybrid too - the track circuit lights are not in the usual Western way of being recessed slightly deep within the diagram, more sat on the surface like a Midland diagram.

Network Rail specified the type of panel (turn push) and the new interlockings at Evesham, Honeybourne, Ascott u W and Charlbury to be E10k.
