Hey there guys. Basically, I was on my way home today and at Euston I noticed that there are two diamond stopping markers on the floor,one either side of the fourth rail. Whats more unusual is that one of them (the one on the RHS of the fourth rail, nearer the platform) looked very shiny/new and had the letter E embossed on it. [The fact its an ATO line and has a new stopping marker was a head scratcher for sure]. So, any idea why there are two diamond stopping markers for Platform 6 and what does the E mean? Thanks  |

Are they at the usual stopping point for 09ts, or elsewhere?

They are probably for the reversing manoeuvre which can be done via the "Euston Loop". The one with E is probably for Engineering trains.

I thought it may be something like that, but it, the E diamond, is right next to the plain old diamond stopping marker, as in, the E marker is no further forwards or backwards from the blank diamond. Surely the blank one would suffice for the engineering purpose? |

The E Diamond is for engineering trains. They are placed all over the Northern line the one at euston is where an engineering train might change from one line to another.
For example going across the Euston loop into the Kings cross loop then past Signal L221 (Provided its showing a Green aspect) over to the Picc.
Theres also E diamonds on transition tracks from non TBTC (Transmission based train control) areas Ie. Depots and some sidings to TBTC signalled track.

Surely the blank one would suffice for the engineering purpose? They're not always in the same place as the diamond, and the engineers driver would be specifically authorised as far as the engineers stopping mark, so a sign is required, otherwise the driver would carry on until realising he or she had missed something! |

Oooh, I thought it was a case of blank diamond implies stopping marker for all trains. Thanks for that clarification. I guess it would be less then useful for a train to try and get in the Euston Loop and end up in Kings Cross doh! |
