Abellio Greater Anglia Class 755s (Regional Trains)

What would make life a lot easier for all, would be trap points at the L/E of P4 at Ipswich, so you can run into P4 in the Up direction, and down into P3 at the same time was looked at when they had the 'Tunnel Block' but was deemed to costly for the actual benefits, so nothing done, I imagine that maybe a regretted decision these days !

Yes. Plus the Cambridge service usually terminates into Ipswich P4 which is quite often occupied at the London End by an Ipswich to London service - so a much slower movement into the platform than if it were clear.

Yes. Plus the Cambridge service usually terminates into Ipswich P4 which is quite often occupied at the London End by an Ipswich to London service - so a much slower movement into the platform than if it were clear.

But, by being a permissive move, removes the overlap issue in the first place (you don't need an overlap for a calling on move)

And it isn't clear at how efficient and dynamic the signalling system is at both Cambridge and Ipswich to reacting to train movements. There are times you are sitting waiting for a path where there do not appear to be any conflicting movements ahead , and platforms are free - especially if the train is slightly early. Maybe automatic route setting to blame here. Seems the computer won't recognise a train is running early and give it the path.

No ARS at Cambridge as far as I'm aware. Signallers don't usually send the 2Wxx early if there is an overlap conflict on P4, and usually prioritise the departure of the 1Txx towards King's Lynn.

No ARS at Cambridge but something like ARS at Ipswich I believe.

@LAX54 can you help?

No, nothing but human fingers and an NX panel at Ipswich, MCS system (with SARS) is from Chitts Hill to Bentley AHB's and to Thorpe-leSoken and Mistley.

One driver told me Ipswich is one of the busiest panels in the UK (by movements) that doesn't have any sort of assistance system.

I still won't forgive you during leafall when you forget about us measly East Suffolks coming down the bank though

From 1999 to March 2020, it was without a doubt one of the, if not the busiest manual worked panel, however it has lost Westerfield to Felixstowe this year, so a little quieter, however it is still darn busy, at 3 in the morning if you check CCF, Ipswich seems to be the busiest in the whole of the UK !
Signaller controls from Ips side of Bentley AHB;s to Stowmarket Stn, and just beyond, and as far as Westerfield side of Boss Hall Junction inc Bacon Factory

Whether the new FL fuel point will make life easier, has yet to be seen !

And there was me thinking the 1Yxx were the measly services that were forgotten about

 

[LAX54]

We don't forget anyone....well not a lot ! 1Yxx can get caught with the 2Wxx leaving, normally if it goes late ! the Up 1Yxx are of course a mere 2 or 3 mins behind an FL, who is reliant on the 1Pxx to be bang on time, otherwise it's a snowball effect

 

[mawallace]

CCF,

what's CCF, please

 

[LAX54]

what's CCF, please

Control Centre of the Future, why it called that I have no idea, it's not in the future, it's not really at the centre, and 'controls' nothing ! It does however show where all the trains are, what their booked route is, and how late (or early) it is, you can also do replays, to see where a train was delayed by a red signal, or regulating delay

Busy, yes, but I don’t think the busiest. Some of the panels in London Bridge, Victoria (Southern) and Three Bridges ASC were busier. Albeit the busiest panel I ever saw on night turn was indeed Ipswich, although that was because the 650v supply had gone and it was TBW Mannigntree to Colchester!

Before the Stadlers arrived the number of times the FL was delayed by the 1Pxx being late which resulted in the 1Yxx being over 10 late by Colchester. Thankfully those days are behind us and the Stadlers are usually waiting time everywhere.

Maybe LB and Vic were busier, and they were a grade higher, but even staff who visited from those boxes in the past, said they would not be able to manage Ipswich, citing that they 'mainly' did up /down passenger, the odd freight and stuff to and from the c.sdgs, they did not have to think about trying to path a loco from one side to another for a loco swap, or trying to thread a late FL in between close running passengers, and they did not control such a big area (for one person)

Well that is true.

Anyone know why the 20:38 LST to Colchester Town is routed via P2 at Colchester instead of P1? Seems to impede the 21:00 LST to IPS getting a clear run into Colchester.

Is there any chance that the Dec timetable will bring the 755s into Liv st?

 

[Ianno87]

With south of Cambridge being blocked this weekend, GA's Cambridge North-Cambridge shuttle employed a 755/3, at least on the Sunday: Picture attached of unit at Cambridge North.

 

[LAX54]

5F93 is departing P1 to the c/sdgs at 2136 (off the Harwich) so that takes time to clear, 1F02 is P2 2139 to 2141, and 1P66 arrives at 2146, so all should be OK, of course the 745's tend to get to Colchester some 3 or 4 early, hence the slow down on approach.

I saw 5P96 running North through Stowmarket yesterday afterrnoon and it was 2x755/4 (didn't catch the numbers sorry). I must have missed the memo because I didn't think multiple running was allowed yet?

5 headcode is empty? Maybe it is only not allowed in service yet.

Can couple as ECS, and have done so for a few months, but not in Passenger service.

And has to be in diesel mode.

Did not know that

I guess this latter part is due to power supply restrictions?

Don't think there are any power restrictions in this neck of the woods. It's software issues agains I think.
