Has a 96stock had a close encounter with the FRLs recently? The new ones are lying on the floor and there is a new one of the old type added! ;D

Ah yes, such events usually take out the track circuit interrupter too! It isn't simply a case of someone having to notice/report the demolished FRLs, when the train moves the track will remain down and cause a signal failure! My last encounter of such a kind was at Ealing Broadway a few years ago. Funnily enough one of my first ever night jobs on signal new works was the additional FRLs in the Moorgate Met terminal platforms back in 1977. Prior to the Moorgate disaster terminal platforms usually had a single FRL in the centre of the track and following it the additional two FRLs were planted ahead of the existing single FRLs.

Yeah I heard on the train radio about this, and that the siding was out of use. Being nosy, I looked on heartbeat. Train overran the FRL's. Maybe he was trying to get to Stanmore.

So what do the extra lights do that the single wouldn't except maybe give a better view etc. I'm from network rail so am unfamiliar with the history of the development of the signalling on LU. I have heard of the Moorgate disaster but am unaware of its relevance to FRL's |

Purely an educated guess - from somebody who has never driven a train - but I assume the FRL is the first line of defence at a terminal (or end of actual line), followed by a sand drag and finally the buffers.

There will be speed controlled train stops on the platform/siding known as TETS, to check the speed of the train down. Then after the FRLs there will be a fixed train stop, then a sand drag/buffer stops/train arrester. |

And since passing (or in this case touching) any red light is a SPAD it is a further incentive for the driver to stop before the FRLs are reached. Defensive driving and all that.........

'Moorgate Control' as I seen it referred to elsewhere. |

Moorgate Control is the NR term, as they like to name signalling controls after places where the incident or situation occured. The LU term is TETS, which is as you worked out.
