SWR Class 458 to be retained

[infobleep]

Would be the 450s, those 450s ideally will be needed in May to ease out some 455s

Would this mea. The chance of more 450s being used on the New Line Guildford, via Cobham?

Yes. There already are several diagrams now, but it will increase again.

One pair of 450s is needed already to replace one of 458/5 diagrams. This week it's been covered by the Staines-Windsor closure. There is a pair of 458/4s diagrammed on Windsors from Monday.

 

[Goldfish62]

Yes. There already are several diagrams now, but it will increase again.

So it sound like SWR's obsession with keeping 455s on Reading services continues. Bizarre.

You'd think so but it wouldn't be beyond SWR to shift the 701's elsewhere and do a press event telling everyone they are continuing the rollout on new routes.

Ant idea which diagram? Hoping it's my morning train to work.

Ah I thought it might have been as early as that. Thanks. Think ive missed that diagram and skipped straight to April. Indeed yeah its a late evening 458/4 run to Windsor that I will manage to catch.

It's very odd that the all day diagram hasn't gone over to 8-450. It starts and ends at Wimbledon Park Depot and looks like an easy and obvious one to convert.
The peak diagram is a bit more difficult to swap round.

0656 off Windsor, 0803 off Waterloo. Repeating every 2.5 hours.

Is this something to do with retaining traction knowledge on 455s at certain depots? Pairs of 455 can't work to Windsor or Weybridge without skipping stops, and I do not know how many other service groups that Staines train crew are involved with that see 455s, other than Readings. Obviously at some point they, like every other depot, will have to lose that knowledge but perhaps for now while the 701 roll out is fragile, that traction flexibility is desirable. I could be well wide of the mark with this idea, but similarly I have been bemused to see this diagram remain 2*455 while five Chessington or Hampton Court diagrams have gone over to 2*450.

 

[TEW]

Staines crews work Kingston Rounders, Hampton Court and Woking stoppers so 455 traction knowledge shouldn't be an issue really.

Thank you. I was uncertain as to whether they had work on the SWML side, but obviously they do. So much for that idea, I will go back to just being bemused.

The peak diagram was to have been the first 701 Reading diagram from June.

If you mean the diagram that starts with 5C07/2C07, that actually starts at Clapham yard, making it hard to swap stock types on it.

Given that 458535 is the only one of the 5 remaining 458/5s that hasn't been in service this week, would it be right to assume that this is the one that's run out of miles and will go for scrap next?

8535 was having brake rheo work done, nothing sinister. 8536 is the one with the least mileage remaining of the 5 cars as far as I am aware.

So it sound like SWR's obsession with keeping 455s on Reading services continues. Bizarre.

Having more 455s run on that side does help as it means the depot can get more units through Mortlake as that is where one of the two Bearing Acoustic Monitoring installations are. The other one is in Swaythling which isn’t so easy to send a 455 through! I don’t think that’s the prime reason but it helps.

 

[OneTrackMinded]

Bearing Acoustic Monitoring installations

What’s that for if you don’t mind me asking

 

[NSEWonderer]

What’s that for if you don’t mind me asking

Monitors the train's wheel/ axel bearings for any defects / early signs of defects as the train passes and if anything of relevance is detected then the system sends out a report to alert the respective team(usually always Fleet) about the issue with that particular train so that the correct action is taken at a suitable opportunity unless immediately required.

I remember when that device was first installed.

Ah interesting, thanks for the explanation

I remember this being a photo used with the official material. The kit is amazing I remember it flagged a bearing issue on a train that was ex-overhaul with only three digits of miles run. We took the bearing for analysis and the damage was a small mark the size of a biro dot on the inner race. Sorry for the off topic. Not like me I know.

Thanks for sharing and adds to the understanding of where various units might need to be used so as to get checked.

I'm not at all convinced about this.

Pre-Covid the only regular 455 workings via Mortlake were the twice hourly Kingston loop services. They still run so I don't see why there should be a sudden need to increase 455 workings to apparently check more units, especially as there are now fewer units in the fleet.

It may be a convenient by product of the 455 workings to Reading but I can't see that it's a reason for those workings.

Looking forward to these being introduced. I am already enjoying them when travelling via Hounslow. As I mainly travel off peak the reduction in seat numbers does not effect me. I think they are very comfortable.

The Windsor 458/4 diagram is a pair of /5s today.
I've noticed that since going down to just one regular 458/5 diagram, there are still enough units to form another 10 car set, and this is frequently used on 458/4 diagrams (presumably either as cover for poor availablity or just to boost capacity)

So 2 consecutive Waterloo departures. 13.03 and 13.06. That's not likely much longer

 

[Juniper Driver]

Just found out I'm learning 458/4s, this would be my third course on them after learning the original 4s cars then the 5s then the 4s again.
I think it's just a conversion, so a short course.
I've driven, 458530 from Woking Bay recently.It was a stock change from the expected 455s.
Originally, my link wasn't going to be trained…apparently.

I believe they are still at Bournemouth Depot. They worked most of the recent Bournemouth to Basingstoke and return trips. but I haven' seen them since March 28th.

And here it is!
The new train smell is very much present
One thing I have noticed though, Regen braking seems to be either switched off or just not working (on 402), which seems odd given it has only just been overhauled/refurbished

I've driven a few recently that had 2 or 3 regen brakes isolated

Are you saying trains are going into service with part of their braking system not functioning ?
