Don't they go there (or somewhere via Wembley) for tyre turning?

Yes they go via the North London Line to Wembley Intercity Depot which is run by Alstom. It's where the Sleepers and Pendos go. They have a wheel lathe the other side of the Watford DC line, you can sometimes see the trains in there from the Bakerloo/Overground.

According to RTT the 1500 LST-NRW was a 4-car Class 755 today - can anyone confirm this? Apparently there was also a 15-car Class 720 to Ipswich as well! I would imagine this wouldn’t happen?

I’d check later. Lots of disruption today with a fallen tree on the Southend & failed freight on the GEML so control would’ve been under pressure. Will get round to updating systems when time allows.

There was a four coach yesterday or Wednesday on RTT but journey check said that those service would now be formed of 11 instead of 4 coaches. The rest of the 755 diagram today on RTT had 11 coaches.

You have to remember that on GA triple traction 755s if split have to return to the depot. They cannot just form different services as their intermediate cabs have not been prepped.

Excuse my ignorance but what prep is there to do other than switch in on and set up the GSMR etc?

Train preparation. It’s because you cannot check anything in the 755 buried in cabs. The agreement is that they stay together as one train and need to return to the depot to be separated and then get a full prep before going back into traffic. In the three years we’ve run triple traction I have never known them get separated yet & often stay in formation all week.

Although surprising agreement I think it's almost never required to be separated in service and in fact I can't think why you would ever have a need to separate them in service as if you separated them at Liverpool street you'd still need to get them all back to Norwich anyway either running empty (so they might as well remain in formation) or by 2 different services and that isn't designed for in the timetable

It’s just the triple traction that this rule applies to. It’s so for example if the train got back to Norwich and it was decided to split one off to save a cancellation on a local service then this cannot happen. The whole train would need to go onto Crown Point depot and start again from scratch once separated.

We have done full testing for trains to separate in traffic and disappear off to separate destinations which would be fine as these units would have all been prep’d singularly before entering traffic.

If anything happens with any of the 3 units on the triple traction diagram then they all must come out of traffic.

Those incidents would be rare I would think but I agree could happen.

In the Anglia Railways days when we had 170s in multi working Norwich to Liverpool Street it was a common occurrence to run short formed to keep local services running. In this modern world however we are a little more flush with units this way so that would rarely be an issue. It’s easy to forget just how tight things used to be.

Sorry I still don't understand. What is there to "check" and "prepare" in the buried cabs? Is it things like checking the head/tail lights are working? I guess they would be obscured when coupled up
Why could the checks not be done by a driver at a station? What special things happen at Crown Point?

All equipment has to be tested every 24hrs or before a train leaves the depot. Apart from internal and external checks including doors, cab equipment such as full brake pressure tests, lighting, washers, GSMR, horn, and ASDO has to have a full prep. This cannot be done in any buried in cab as these are effectively dead once coupled on 755.

There are certain faults a train can enter traffic with from a siding or station that would not be allowed if they are on a maintenance depot too. This is why trains with certain faults try to get held away from a maintenance depot if at all possible as once they go onto it they cannot then return to traffic until repaired.

The train forming the first Lowestoft to Ipswich on weekdays and the first Felixstowe on Sundays are 2 units coupled together. Does this mean that they're prepped separately then coupled before leaving?

Yes mate, that’s exactly how it happens. They can be coupled & uncoupled all day long just as long as they’ve been done separately.

What happens (or happened) with Sprinters and Pacers? To use a Cardiff example, pairs of Pacers would often run around for days but could split at any moment to cover a failure. Is it possible to do the full prep in coupled cabs on older units?

I'm assuming it's a bit to do modern units 'situation awareness', you probably can't have a unit going around with a fault and warning message in the cab where on a sprinter you'd be none the wiser.

It’s very different as the 755 cabs are dead once coupled. These are then uncoupled from the outer cabs. They do couple/uncouple all day. As I stated, it’s only the triple traction set that covers a main line diagram that has a different agreement as these three 755s stay together all week.

No it’s more to do with train prep each day than anything. We had fault indications with 15X & more so with 170 units.

Are both units unlocked? Or is it just one towing an empty unit?

I believe they’re empty coaching stock moves.

Example:
  • 5J61 0442 Norwich Jubilee Sidings to Lowestoft formed of 755406 & 755412 on 17/06. This then forms 2A04 to Harwich International, and 2J61 to Norwich.
  • 5W04 0715 Ipswich H.S. to Ipswich formed of 755404 & 755413 on 16/06. This then forms 2W04 to Bury St Edmunds, and 2A90 to Harwich International.

  • Was working that very move remaining with 406 for a few hours.

There's also the 11 car 5P84 2346 Ipswich to Norwich crown point

Also, does the name on rtt stand for Norwich Crown Point train and rolling stock maintenance depot?
