Southern Class 455 PRM modifications

[Class455]

Has the 700/707 production line been shut down? They could always produce some more.

No thanks

GN Moorgate 717s will surely continue on from 700/707 anyway?

It wouldn't totally surprise me if PEP EMUs were in better nick than Mk3 EMUs because of the ally bodies.

It’s only an aluminium skin over steel pillars , a lot of 1970s products , pep and mk 3 coaching stock had expanding foam pumped into the solebar , the 507/508 that were repaired by wabtec in 2009-2010 didn’t suffer from solebar corrosion, just pillar corrosion behind the door pocket sheer plate, this is common on the mk3 mu stock also
Expanding foam tending to stop water ingress which can happen from leaking window rubbers or poor sealing in the door trough area , the down side is the poisonous fumes given off when burning, this meant it needed to be removed before corrosion repairs could be done

Something I noticed yesterday was that 455 815 is most probably the only full unit not to have LED lights in any carriage. It sure looks weird, especially when you get used to the 455's with LED's.
Is there any reason why Southern decided to fit only one or two carriages with LED's on some units too rather than the full set?

Think 455816 has gone to Wolverton...just needs confirmation

Really good to see the first unit finally going for refurb. Hopefully when the moves are in full swing I’ll catch one on the WCML. I thought the work was going to be done in house? Maybe it could be more than just minor work....

Is this a regular working?

 

[Class455]

I have added a list to the top post on Page 1. Please let me know when updates are required!

this is the first unit to go from Stew Lane to Wolverton. Im not sure if there will be 1 per week etc etc

Believe a second unit departed for Wolverton yesterday, with 816 returning. Can anyone confirm which unit went to Wolverton?

EDIT: Have now found a photo on Flickr, 57303 took 455839 and 455831 to Wolverton.
Hopefully if 455816 is back in service, I will go and hunt it down on Tuesday.

Currently on 455 805 and it has new door alarms!
Seems as though the door alarm work is being carried out in house, whereas the rest of the work is being done at Wolverton

How different will the interior be?

 

[Class455]

How different will the interior be?

I’m not sure but going by what I read I’m guessing the “revised seating layout” will be minor. There will be new gangway door handles though, as well as some other features. Guess we will find out when 455816 returns to service

The opening tone on the new door alarm on 455 805 can’t really be heard from inside, as it can only be heard from the speaker on the outside but the door alarm only plays on the inside when the doors close. Is this the case on the PRM modified 313’s or is that something that will be rectified later on?

They sound exactly the same as a Class 700’s door alarm

Yeah it seems to be the same.

I’m quite suprised that power sockets aren't going to be fitted to the 455’s, considering Eversholt are currently fitting the 318’s with them.

The motor alternator would not be able to cope with plug sockets! You would need to replace the MA with a static converter, something SWT looked at a couple of years ago but was too pricey. The cab air con puts the MA on the limit as it is.

455816 now back in traffic.

 

[physics34]

455816 now back in traffic.

only seemed to have door open chime and new internal handles.....no changes to seating layout.

 

[IKB]

Went one stop on 455810 today. It has new doors buttons on the exterior and a much louder hustle alarm. Was only on it briefly but nothing about the seating/covers struck me as any different.

 

[Class455]

57303 hauled 455844 from Stewarts Lane to Wolverton yesterday. Believe 455839 and 831 are now back but will await confirmation before updating the list

 

[Milo T.K]

Class 455816 seemed like a normal pre prm 455 to me as I went on it today

 

[Class455]

455814 now has new buttons, seen today at Selhurst with 455819 (unmodified)

 

[Class455]

Have today seen two of the units which went to Wolverton, 455 839 and 455 844 and from the outside it looks like nothing has been done to them. There aren’t even new door buttons. It makes me wonder what is actually being done to the units at Wolverton?

the only other things that are happening as far as i know are new door handles on the doors between coaches and a slight change in seating layout. Not sure what is being done where!

 

[Class455]

Meanwhile, 455805 was taken to Wolverton by 57301.
Hopefully if there is a move this weekend I will go out to catch it.

 

[Class455]

455802 with new door buttons, seen this morning at Purley

 

[physics34]

Also 455845 with new door buttons and chimes/alarm. The door closing hustle alarm gives less time than previously to get clear of the doors

Any reason why the second door button has been covered up? Surely they could’ve fitted another button similar to the SWR 455’s. I noticed that other BREL units however only have one door button.

I wonder if the units that have visited Wolverton have had door work done on them to make the doors shut slower, like on the SWR 455’s.

probably money saving ie less maintenance. I also notice the door open/close buttons inside are the other way around (close at the top).
