I'm only aware of 23 units out today, 013 and 039 being the absentees.

That tallies, the 23 701s that were in use plus the one 701 diagram that was covered by 5728 + 5737.

Reading - Wokingham is open tomorrow, so it should be 25 701 diagrams as of tomorrow. Whether there will be 25 units available to cover the 25 diagrams is a different matter!

There have never been more than 23 on the same day, but that has been acheived for five weekdays in a row now.

On a positive note 92% availability for a new fleet that is still being introduced is pretty respectable - hats off to all involved!

701033 and 048 are having their entrance checks done, one or two issues on 048 to be fixed which arent major from what I hear, both enter the testing cycle after that and will wait their turn before seeing service.

Pardon my ignorance but is the testing cycle you refer to the same as fault free running? If it’s different, how long does it take assuming no further problems?

Better than you'd expect for an established fleet and a tall order for a new fleet to achieve!

In the latest Modern Railways reliability survey, after a few periods of stagnating at around 3.5-4k miles per failure (known as 701D), reliability improved to over 9k miles per failure in Period 4 (four weeks starting late June).

The issue seems to be the very slow progress in clearing units for service.

Very true - its is a good reliability figure even for a bedded in fleet.

I will call that very thorough acceptance testing, which is a respectable way to do things 8-).
(my bold).

Just to keep the testers busy. Next delivery to Wimbledon from Long Marston is in the system for tomorrow evening - Wednesday 29/10/2025.


5Q70
14:35 Long Marston departure
18:52 Acton Mainline
18:58 Willesden (low level)
19:17 - 19:22 Clapham Junction Pl 6
........ (round the Kingston loop)
20:24 Wimbledon Stn
20:31 Wimbledon Park Depot arrival
But the deliveries usually run early. Allow an hour so I usualy aim for Wimbledon knowing I can catch it an hour early at Clapham Junction !

For those wanting advance notice the light loco from Leicester is
0V70
08:51 Leicester departure
12:31 Long Marston arrival

Why do they go round the Kingston Loop rather than the direct route via East Putney? Is there a right way round and a wrong way round for them? Or are locos not allowed on that route?

Yes and no, the cycle is what all units that become passenger service competent will do. Various tests, then used on trial runs and driver training and then when ready deemed passenger ready, this may have been tweaked lately to expedite the process but its pretty much what all the current passenger running units have done, nothing new.

I assume it means less conflicting moves.

If the delivery from the Willesden direction were to go the short route then it would have to cross the entirety of SWR tracks at Clapham Junction to gain the down slow or fast towards Wimbledon. It would then have to cross again to get to the depot. Note that going via East Putney would require a reversal (run-round) at/near Wimbledon station to get into the depot (the half of the depot nearest London btw). It also leaves the locomotive in the right place to go forward back to Leicester.

As units that are not accepted for passenger service they need to be positioned in the Maintenance section of Wimbledon depot, the East depot (London end, Earlsfield side of Durnsford Road bridge) in the first instant.

Entering the depot off the East Putney line at Wimbledon Park station would mean a reversal on the washer road and a propelling move London bound under Durnsford Road bridge, causing a blockage of all other movements in the Top yard (the stabling sidings visible alongside the LUL District line) for perhaps 10-15 mins, but I also suspect that a 10 car plus loco, is in reality too long physically to undertake such a move (within depot limits). One has to 'know' the depot and various shunt limitations to understand the finer detail.

Therefore the best (possibly the only) viable route in to the depot is off the Up Main Slow through Wimbledon station, in to No 1 Reception road which allows a head on run under Durnsford Road bridge in to the East depot, a move that will take (perhaps) 5 mins in total within depot limits and thus causes the least disruption etc.

PS: in addition to other (similar) very valid points made by Peter Sarf whilst I've been typing (lol!)

There is no direct route from Latchmere Junction onto the SWML down tracks. You would either have to route into the Clapham Junction sidings and reverse towards Waterloo and then reverse again onto the SWML down, or route towards Queenstown Road, and then reverse on the SWML. both of which would seriously mess with the large amount of services on the SWML.

This is why the Tolworth Sidings/Chessington South Sidings to Willesden Junction aggregate trains route via Haydons Road and the Brighton Main Line from Wimbledon to Clapham Junction. This uses the dive-under route to Latchmere Junction from platforms 16/17 at Clapham Junction.

Quite right. Such a route would never be considered in the planning sense for moves such as those in question. As I touched on, the route off the WLL would be down the Windsor Slow line and turn left via East Putney, Southfields and in to the depot at Wimbledon Park station, but again as said, a 10 car plus loco is, I believe too long (within depot limits) for that to work, in addition to the excessive time such a shunt would take within what is a very busy depot.

Thanks. I was not 100% sure that there was even a suitable link onto the down SWML from Latchmere Junction (ie from the Willesden direction). If there was then the impact would be on the entirety of the routes to/from Waterloo !.

Indeed. Having watched proceedings at Wimbledon depot there are times the depot/sidings entrance appears quite likely to be operating at its limits.

Also I am not sure there is even much space for a lumbering freight in amongst the district line services. Especially as it gingerly tries to take all available reversing/headshunt space (if the space is even long enough) !.

Having joined a District line train at East Putney for Wimbledon last Thursday morning, we got caught behind a simple Class 450 movement from Waterloo to Wimbledon Depot via Point Pleasant Junction. We had to wait 5 minutes at East Putney after the 450 had passed, and a further 5 minutes between Earlsfield and Wimbledon Park whilst the 450 entered the depot. By the time we made it to Wimbledon, then next two district line trains were right behind us.

That (via Earlsfilel) is not what I was suggesting, and is not possible anyway as there is no link to the SWML from the West London Line except via the Windsor Lines or via Tooting. Other posters have explained why Point Pleasant/east Putney is impractical

Thanks. I thought it mighht be soemthing like that, but hadn't appreciated that the train wouold be too long - I assume a 10-car unit on its own (sans locomotive and barriers if any) could enter the depot from that direction though?

To be clear I was assuming barrier vehicles as well - should have made that clear. 10 car EMU and 12 car on their own, can and do enter the depot via Wimbledon Park station (LUL) entrance, thence run via one of the reception roads to gain access to No 1 or 2 washer roads.

It is one of these two roads that any move such as the 701 delivery being discussed would have to access if running via East Putney, before being propelled by the train loco London bound to the East depot, which whilst doing so would effectively stop any/all other moves in that (west end - Top Yard) part of the depot, which being the major stabling area for service trains is the busiest for service train movements.

So running via Kingston and the Up slow line, entering the depot via Wimbledon station (p5) and No 1 road in the depot, the move is in effect just one additional pathway taken up entering the depot, hence minimal disruption to other moves. The loco detachment and any subsequent unit shunting taking place in the East depot at a time convenient to the depot and loco driver, and not reliant on having to fit in with the wider timetable schedules associated with the main line.

Today's 2M03 onwards diagram was due to be 455-worked (vice 701) but this was cancelled anyway due to Wimbledon issues early this morning - not sure if the diagram was picked up later in the day. This seems a common occurrence for this diagram on Mondays anyway (455s replacing a 701).

This diagram has been 455 operated every day this week so far

Yes - although in the 2 weeks prior to this one, it switched to a 701 from Tues onwards (I think!)

701 044 has belatedly picked up one of the 701 diagrams today with 2J25 W'loo to Hampton Ct (departing from W'loo Plat 18)

Funny how they keep releasing new 701 diagrams and yet they can't fully run the current ones...

Yes, I really wasn't expecting a new one next week.

Unless there are further 701s being passed for passenger service before Monday I make that 25 units to cover 26 diagrams!

At this rate they may as well convert everything over to a 701 diagram, I'm sure the DFT can get creative with a headline
