There was a 345 in the "Shenfield stub" about 0815 on Tuesday with the DMI reading "Heathrow T4" By coincidence I was at Chadwell Heath about 09:20 this morning and an announcement was broadcast advising passengers customers travelling towards Reading to ensure they had the correct pass/ticket/authority to travel beyond West Drayton. Perhaps the core will open in secret soon?  Signs are everywhere, literally! From diary’s in WHSmiths to purple roundels that occasionally pop up at interchange stations and the 345’s which already have their full complement of destinations. Paper tickets even have “via Elizabeth line” marked on certain journeys. Further note to add: On Sunday 19th May testing of the signalling transition zones between the core and the Eastern Branch will see trains potentially displaying far flung destinations. |

Some comings and goings at Stratford today (Sun 19 May) with TfL Rail services using the Greater Anglia platforms. A class 345 at platform 10a.  Two images of a Elizabeth line 345 idling at the cordoned off Platform 8 having just emerged from the core.   |

The main GA platforms are 9 and 10 for that service. 10a is sometimes used for Norwich services.

Indeed, that's true as well. There are signs for a 9-car stop there.

The compressors were humming away for quite a while before and after the photos were taken presumably for emergency brake tests giving off a sound not to dissimilar to the S stock. |

Not surprising; they may well use the same compressors as the Bombardier Movia, the family to which the S Stock belongs.

How many compressors do Class 345 trains have? Two is barely enough on S stock once the compressors are coming due for overhaul and their efficiency goes down. |

I would guess 3 or 4 perhaps. However, if the S stock only have two I don’t know! I would like to think the latest compressor types are more efficient than the older types but I’m not certain. I’d be very interested if knowing the answer if anyone knows.

silenthunter , t697 and metman , Just been talking to a colleague more accustomed with rolling stock who has passed on some technical specs for Bombardier stock. The S stock, Class 378, Class 345 and Class 710 all use the same Knorr-Bremse VV120T oil free reciprocating compressors. There are slight variations in how they are powered, but they would indeed sound more or less identical.

This is to allow all up trains on the GEML to use the full width of 9 and 10 to disgorge passengers. One day last week the 0838 Norwich was formed of 3 x 321s, much to the annoyance of those who had reserved seats or wanted the cafe-bar. |

Is there any noise re the remainder of the Cl 315s being replaced by often static Cl 345s west of the City... or have these already been extended to 9-car units...??
If so, does this mean that some Cl 315s might see in 40 years of use?  |

I believe most of those stabled in west London were built as 9-car, except the few running Paddington-Hayes which remain as 7-car. |

You still need to extend the platforms at Liverpool Street High Level first; 9-cars won't fit at present.

Wasn't there a closure of Liverpool Street already to extend the platforms?

Wasn't there a closure of Liverpool Street already to extend the platforms? No it was due this Summer. There has been no public statement to indicate when it might now take place. There are some pretty big commercial issues knocking around any retiming of this work because of the Greater Anglia franchise timetable changes / introduction of new stock. Until there is a bit more certainty around when Crossrail core can open we can't begin to guess when the Shenfield services would be slotted in (theoretically 6 months later) and then the Liv St works done. There is a little bit of me that thinks that there may be an eventual decision to scrap the planned peak 4 tph Crossrail services into Liv Street thus negating the need to do the platform works. I suspect the pressure for this will come from DfT who will not want yet more disruption on the Gtr Anglia franchise that is already in a financially weakened state. TfL may well agree as they will not want to foot the "compensation" costs to Network Rail and Greater Anglia. We shall see if my mad musings prove to be correct.  |

If the work is planned for this summer, why not just do it? 12tph on the Shenfield line would be s disaster in the peak. Cannot believe that it would even be discussed as an option, because it simply cannot be. |

Cannot believe that it would even be discussed as an option, because it simply cannot be. Had been planned! Given last August's bad news re Crossrail and the continued stream of project slippage I suspect Network Rail sought clarification and then decided to stop planning and removed any possessions booked into the calendar. Something as big as this would take at least 2 years planning, possibly longer because of the impact of the work. I think it is possible that once Shenfield services go into the core that they may well have to survive with 12 tph in the peak albeit with longer trains. I say this because *if* the Liv St platform works do happen then I doubt a 4 tph TfL Rail service would be run into Liv St during the works given the need to somehow still cope with Gtr Anglia's services. I am guessing here - I have no specific info / insight as to possible working arrangements. |

Why not just divert some trains into Broad... Oh. That was a good decision then.

There was a connection, via the North London Line and the East Curve at Dalston (closed during WW2), but it was not exactly direct.

IME, so many people alight from the Shenfield slows at Stratford and don't go on to LV, there isn't generally a crush in the cars between there and LV. There is, of course up to Stratford, but hopefully the longer 345s (when they actually are longer) will soak up at least some of that. There's also many more people in the front of the train, with the rear (and its long hike to the barriers) relatively empty. That won't apply so badly after the core opens. I've said in another thread that I reckon the cross-platform interchanges at Stratford will become even more congested, ditto the staircases and passages, after Crossrail |

Just to confirm that the weekend transition tests are using nine car trains with Elizabeth line logos on the sides.

Looking for a Liz roundel is probably the easiest way to tell whether its a full length unit or one of the 7 cars without actually counting. |
