The trains still have major WC issues. Or maybe it is just the SWR policy to shut them later in the evening?
Shut them later in the evening, just when they're likely to be most needed?! :lol: :lol:

Wouldn't explain why they're not working in the morning, would it?

The toilet issues, explained somewhere earlier on this thread to be mainly due to the water tanks not being replenished during the day, do seem to be getting worse though. I'd say there's now less than 50% availability at any time of day, with both toilets out of order being common.

It makes sense that passengers will be getting used to the existence of loos on Metro services so over the first year or so the loos will be get a rising level of use.

That doesn't apply to Windsor lines services where we've largely always been used to loos on trains. All my observations are on Windsor lines services, not on "metro" services.

I'm not sure I understand your argument anyway. Are you suggesting that once passengers "get used" to having loos on their trains they'll use them less?

I expect passengers will be using the loos more and more so there is more chance of the loos being out of use. That is unless/until the loos (tanks) are serviced more often.

Loos may not be a new thing Windsor side BUT I suspect the 701s are out in service for enough days between loo servicing that they are getting filled up (or running out of water) on other Metro services/routes. Then when a 701 ends up on a Windsor service it might already have been used on non-Windsor services enough to put the loo out of action !.

My argument, above, falls down if 701s on Windsor services never get used on non-Windsor side train services between Loo servicing events - does anyone know ?.

I would not yet rule out other factors :-
Like if most of the hand washing water goes onto the floor !.
(that's enough speculation).

There was 701504 making a move yesterday at Clapham Yard around 19:50. Not sure where it was heading.

Given the bio degradable nature of the content of WCs on 701's, the tanking would seem to be the issue, and assuming the tank access point can be accessed at platform level, the first thought is that old school bowsers need to be employed on both Main Sub and Windsor side platforms at Waterloo is the answer, surely?

But without understanding the complete bio-bog/waste water disposal system employed on these units, one can not make an educated comment as to why there seems to be a problem in this area.

Yes, according to RTT 701016 is in service today and 701040 is on 5Qxx trips, so may be nearing entry to service too very soon.
701040 seems to be a record setter for out of storage and into service. Would be great to see it but not holding my breath!

701s can now as of the last couple months be re-filled with the water browsers/tanks at Waterloo. There was some sort of restriction IIRC. As far as I know water browsers can only be found at Waterloo and at some of the depots (not all). The biggest issue really is that it takes a bit of time to refill the tanks, at least 10 minutes or more I believe to refill both toilets (don’t quote me on that but that’s what I think I remember), which isn’t very long - most trains that arrive on the suburban side of Waterloo are usually in and out within 10 minutes at most, even less if they are slightly delayed. So that’s the actual real problem to be honest, they need to figure out a way to either make the refilling process quicker, which is easier said than done.

I do agree though with the general point that it is a bit ridiculous how often the toilets are out of use. It is very rare both toilets are found to be working. When the toilet runs out of water it locks itself out automatically, which can be identified by a flashing slanted line across the ‘WC’ logo in red. It’s very inconvenient, especially on late-night services or on weekends in my experience…

SWR have had years to plan for this...

Seems to have struggled a bit


Separately, how does one pronounce "Arterio"? My local station's announcements always said "Arteerio," but the announcements at my local station have since changed and now pronounce it "Artehrio".
I was on it. Didn’t realise it was it’s first trip out though.

The fast run from Motspur Park was great for me - got in on time from a ten minute late start at WCP.

I mean a simple answer would be to fill them as much as they can within the available time and not work on the basis of requiring a minimum of ten minutes to be able to fill the entire tank.

Or top them up at every opportunity, rather than wait until they are empty.

Both of you are making it out like it’s a very simple thing to do. It does not work like that at all, and just refilling them a little would be an extremely inefficient and ultimately wasteful way of doing things considering how water-hungry the 701 toilets are.

It isn’t like there’s many water browsers in the first place. There are only a few, and the sheer number of units that have at least one toilet locked out due to insufficient water levels means realistically it would be very difficult to attend to each unit considering the suburban turnaround times

Realistically the only way things change is they either need to commit to investing in some more browsers, or to find a type of browser that can refill (and move) much quicker. Easier said then done, but the water browser guys do their very best to try do what they can with the resources at hand.

So the inescapable conclusion is that SWR screwed up the specification with water tanks of too small capacity.

Not having a go at you for reporting the issues, but it all comes across as the standard railway excuse that everything's far too complicated to be able to do anything about it.

This should all have been thought of years ago with a plan in place to ensure that tanks are kept sufficiently topped up.

If SWR really is claiming that introducing trains with toilets replacing ones without, and promoting this feature, but then saying that it's too complicated to keep the toilets in use on a day-to-day basis, then that is beyond incompetent.

Regarding the 10 min required to fill the tanks, the vast majority of Windsor lines services have at least 15 minutes at Waterloo, yet toilet availability is just as bad.

This is a solvable problem. How much is a bowser for this use case? £50K? £100K? Buy 8-10 of them so you have coverage across all platforms at Waterloo thay 701s operate from.

Last I checked, 701’s have realtime reporting. So in theory, the Waterloo team can monitor the status of the toilets on a train departing Clapham Junction. Identify which toilet has is OOO and the have plenty of time to move the bowser to the correct platform and location to fill that tank.
Better yet, a simple alert from the train could be triggered to the Waterloo team when toilets are OOO so they are ready for it at Waterloo.
The real solution probably comes once there is the full roll out of the 701’s as it makes it much easier to swap units from one diagram to another to allow additional time for tank refils.
Another alternative is to install refill points at places like Chessington South, Dorking, Hampton Court and Guildford as the units spend 15minutes+ before starting their journey back to Waterloo.

And who is going to man those bowsers?
You’d have to re write contracts for train crew to do that and then comes the unions disputes etc

That's a very negative approach, if can have people contracted to collect litter from carriages, wipe tables, clean toilets etc at suburban termini where there are long layovers, then presumably it's not hard to get same person to top up some water.

On SWR I have never seen train crew going through train cleaning it, so I suspect any water refill would never be anywhere near train crew duties.

I agree it is a bit embarrasing. I wonder if the situation will improve when the whole fleet is in service. Perhaps currently there are diagrams that preclude convenient water stops.

It is going to be the staffing costs that will kill that idea. Furthermore it SHOULD not be a reactive task but one where the tanks are topped up often enough. But it depends how time consuming it is to connect the water supply and disconnect the water supply. It occurs to me that it is also a safety consideration before the train sets off !.

What would be prudent is a filling regime that is not reactive.

I agree its probably better to do it at the country end.

I can see the challenge being these cleaning staff are then being expected to attach the train (that can move) to something on the platform (that might get dragged along). Not the same as a cleaning staff member getting left on the train when it leaves. More coordination and training required.

Overarching question is - how often do these tanks need filling and what is the current planned frequency ?.

This all assumes it is not a waste tank full problem but merely the water supply tank empty ?.

The door mechanism is also a problem on these units. The lock sometimes doesn’t activate and lets someone open the door whilst someone is sat on the toilet!
