I thought the train hit the signal?.....where's the damage?
Don't tell me that it was known it had fallen (and photo taken), and the train *still* hit the signal...
Or was the original report an exaggeration? :-)
The signal is mainly lying across the DM, whereas 1A83 was on the UM. The train hit the junction indictor on the top of the signal, so damage would be seen on the other side of track. If the train had been on the DM and hit the signal at 100mph, I wouldn't like to have seen the result  . There is certainly damage to the power car in question, as i've seen pictures, although not able to post here. |

Are there track circuits there or axle counters?
If TCs‡ would the metal falling across the DM have thrown the previous signal back to red? Presumably it would have fallen in the overlap of that signal.

presumably the signal wasn't at danger when it fell over? If it was then surely the train shouldn't have hit it.

It applied to a different track to that which the train was running on, as per post #7 #30 above. Another 'post' that moved suddenly...  Paul |

We have been discussing this on another board. Would it be possible to merge the two threads?
Ought to be here?...
With thanks for your various constructive suggestions, this has now all been done. CfN.  |

You can clearly see the mode of corrosion failure. Very difficult to protect for this as it is normally at the groundwater/air interface. It can also be inside the tube as well as outside. |

... and, purely as an aside, I note the signal fell right across one of those toast rack / shopping trolley things - an image so beloved of journalists trying to illustrate their railway stories.   |

Joking aside. There was time to grab a picture but not stop a train hitting it?  I guess if the signal failed completely (and not stay at danger) it would have been spotted more quickly? |

The picture was no doubt taken after the train hit it. As pointed out earlier, the train that hit it was travelling on the Up line which is the farther one in the picture. The three position junction indicator (colloquially 'feather') was hit and the class 43 that hit it suffered damage, primarily to the air system. The service involved was 1A83 (1041 Truro - Paddington) and was travelling at line speed of near 110mph. The signal hit (T2825) controls the approach to Newbury station with 'feathers' for various moves to access the platforms at Newbury. The junction indicator was reduced to a bag of bits. It's axle counters in the Newbury area. Even so there's no guarantee that had there been a track circuit on the Up line it would have been de-energised by the the junction indicator laying on the rails. From other forums, I'm led to believe that the RAIB▸ are investigating.  A schematic of the area, showing the signal concerned:  The signal post in its correct perpendicular state, as seen on Street View:  |

They've got to!
Imagine if that train had been on the Down....doesn't bear thinking about.
NR» will get some serious bad press....

How about putting a weight on every signal on the side from the trackside. That way, in the event of a repeat, the signal will naturally fall away from the track. But seriously, that would have been a dead cert derailment if a train had come the other way. And with a set of points ahead and station, indeed it doesn't bear thinking about. |

Had this one fallen t'other way it may have fouled the Down Newbury Loop. Slower line speed on that one, but still the potential to cause a serious incident. I suppose weights could be attached to ensure they fall parallel to the track. Or Network Rail could maintain their assets such that they don't get into such a parlous state. |
