To stop people falling on the track I would assume. As trains don't berth at that part of the platform, then it would be dangerous to have an unnecessary drop.

Why would it be dangerous?

Track & Ballast...? Sounds like a name for a pub!

Ok... Totally off topic, but i was bored:

;D

That looks just north of Sandown station on the Island Line where the line converges to single track, can't be sure, would know for sure if you post a large pic.

If that is the wrong answer, it's got to be somewhere on 750v DC land...

Er, because it's a 80cm drop.

In what way is that dangerous? Isn't a tube gauge platform even higher? Are people incapable (with the obvious exceptions) of seeing that there is an edge?

Why is there this attitude of treating perople as if they are stupid?

I must say that AGC is right unless there's something we've missed. Otherwise by stephenk's logic no passengers would be allowed on any part of any platform unless a train was berthed there (shades of the annual beer festival on Minehead platform where trains are stabled deliberately:but that's another story).
That logic finishes with trains not being allowed to stop if there are not PEDs. So why railings at Stanmore?

I take it you've never had to fill in a risk assessment then! Whether people are stupid or not, accidents happen. Someone can be killed by a head injury from a fall of that height (or less). So it makes sense to put barriers on parts of platforms where trains don't berth. It's pretty standard practise on many metro systems around the world, including LUL to barrier off unused platform faces.

"--Treating People [Passengers] as if they are stupid"

Need we say ? :-)

Whilst i've never been to Stanmore, I do know it's a terminus station - when a train terminates, you generally get a lot of people leaving the platform in a large group..............so the barriers do make sense [if only to me].

I'm glad someone agrees with me!

You wouldn't find a pavement raised at 80cm without there being railings, so likewise any unused part of a platform face should also have railings.

[DWS]

Stratford Jubilee Line also has railings at the terminus end of the platforms.

If you look at a very large number of stations, many will have barriers / fencing taking up the remainder of a platform should the normal stock using the station be shorter than the structure of the platform. It is the standard now employed (known affectionately as the Platform-Train Interface) to ensure customers remain more or less within the designated area where we will provide a service.

One example which springs to mind is Edgware Road Platform 4. When the re-signalling was carried out, the stopping mark was moved back east slightly. The distance between the exit stairs and the new stop mark was filled with barrier fencing.

When you think about it, it isn't because anyone is stupid. In fact the result is to prevent anyone looking stupid. Take my example above. Without the fence many people would wait on a section of platform and, when a train arrives, look pretty silly when it stops short of them.

Surface Stock are restricted (but not banned) from using platform 1. One reason is the "Tube" style buffer stop which could cause a bit of a problem should a hefty great A-stock require its use.

The E/B District at Mile End could do with fencing from the monitors to the end of the platform. The Central Line trains stop much further forward and quite a few people stand expectantly near the headwall of the crowded platform, then look very miffed when you stop 10 yards short of them. ;D

Also Plaistow and Dagenham East have a situation where there is a double length Eastbound platform and the train stops at the Eastern end. Unfortunately the bay road is level with the unused end of the platform, so people tend to get off a reverser in the bay, walk straight across to the adjacent Eastbound, only to see their Eastbound train shoot past them and stop up to 6 cars away.

However the double length platforms could be useful in an emergency as it allows another train up behind (passing signals under rule) to detrain easily instead of being stuck between stations, so fencing would reduce flexibility.

[Tomcakes]

Could they be gated, released by an LU staff key?

[stanmorek]

If I remember, the handrails for both platforms were put up in the last year or two at about the same time the new style buffer stops were installed. Before then trains would stop closer to the buffers.

[Tubeboy]

Its been a while since this thread was updated, anyone know the latest, regarding the third platform. It will be very useful once it is in operation.

[towerman]

There's a new WTT9 starting towards the end of May 2007 with 18tph off peak,I would imagine it would be available then.

I'm afraid not - WTT 9 has been compiled as the current line geography, and no third platform at Stanmore to use.

[towerman]

I hope they've sorted out the congestion that occurs at the north end of the line at the end of the evening peak with empty stocks running from Stanmore to Neasden to stable.

I'm told it will be March 2008 by the time the 3rd platform comes into use...

They have done their best to redress the issue. To be honest, I doubt it will alleviate it to any great extent. The only real and practical solution to that problem is to have the third platform at Stanmore. And I’ve heard horrible rumours about it not being made available for ages.

[towerman]

Was at Stanmore during 2005 when the work was about to start,the posters about the project on the platforms and in the ticket hall gave a completion date of summer 2007.

[stanmorek]

An update:
- No indications that the track nor the platforms will be going up yet;
- Gabion wall built near the existing station buildings near the north end;
- Some temporary formwork moulds for concrete in place towards the north end;
- A few reinforcement cages still lying around so more concreting work to be done. There appears to be some work on deep excavation shafts;
- Some more piling work carried out at the south end close to the junction. The cable run is still intact with no signs of diversion work;
- A new brick work building has been built south of the sidings. Presumably to replace the demolished signal cabin;

[Deleted]

The new brick building is probably SER 'JL', and is more likely to be the replacement for IMR 'JL', which replaced the now-demolished signal cabin.

Went past a day or two ago, thought it looked like there was some sort of foundation-related work being down where the platform is due to go.

[towerman]

There are some closures Stanmore-Wembley in February/March next year.

Maybe they could solve the problem by not sending a train to Stanmore every 2 minutes, especially since all the trains are virtually empty outside of the peaks! Anyone would imagine the third platform would be open already looking at the timetable!

[stanmorek]

Some weeks ago a new overhead gantry/cable bridge went up at the crossing for the roads leading to platforms 1 & 2. Even though there is not track laid yet the span of the gantry looks long enough to accommodate the new road from the third platform.

They have to, they can't possibly reverse more at Wembley or Willesden, this already causes blocking back.

Some photos.



The first photo was taken some time last year. An earth berm (behind the blue hoarding) was built up at the toe of the cutting to give access to a piling rig. A row of closely spaced piles were sunk in a line along the whole length of the cutting. The formwork for the pile caps can be seen at the top of the berm.



Some months later the berm is excavated down to track level and the trackside face the of piles are exposed to form a retaining wall. What you see in the photo is after waterproofing and concrete has been sprayed onto steel mesh on the wall. In the background is a concrete wagon with telescopic pump boom.



This photo is the latest taken during the weekend. The platform piers have been cast and precast concrete planks are going up. The piers are piled foundations while a ground slab has been cast with service chambers and drainage.



There are starter bars protruding from the piers for anchorage for the next section of concrete pour. Also the circular steel cage to the left appears to be a new column support for the canopy structure.

It is interesting to actually see some sort of progress at Stanmore.

Not too long ago i contacted tube lines regarding the new platform mentioning that parts of canary wharf and London Underground have been built much quicker then this one extra platform at Stanmore. So why is it taking so long?

This is a part of the reply-:Thanks for your recent feedback form.

The third platform works at Stanmore is in fact on schedule. The scheme is project managed and conducted by Tubelines who have years of experience. We have our regulators in place to ensure that the works are carried out in a timely, strategic but rigorous fashion, whilst ensuring they adhere to all health and safety compliances.

The publicity on site states that it is not scheduled to open until 2009, when a new signaling system will also be commissioned.

Still the mind boggles at to the reason for the extremely lengthy time to install this platform.
