I've now been commuting to Moorgate for six months, and one question is bugging me... why do down trains use SDO at Drayton Park so that only the front 5 cars release the doors? No up trains do, the platforms appear pretty much the same length, and on all bar one occasion down trains have fitted comfortably in the platform (I usually stick to the rearmost car so I can see the doors well clear of the stairs). It seems to catch a lot of people on the platform out...

Why the SDO at Drayton Park?

Similar to some other GN stations, Hornsey and Harringay spring to mind, where clearly a risk assesement says that unless the driver stops just right there may be some risk that a door might not be fully on the level part of the platform with a consequent risk to passengers not looking where they are going. And no-one wants to spend the money extending the platform by a few feet. Similar at Longcross.
Tulse Hill Platform 2 is a bit of an odd situation. In theory the platform is long enough for 8 coaches and the stop marker is all the way up the platform but they all stop slightly short and the last couple of doors do not open.
A long time ago, like 25 years + that platform at Tulse Hill had 8 carriage trains and all doors opened. But like West Norwood in the Victoria/London Bridge direction, previously all 8 carriage doors opened. Admittedly for the last carriage this onto a rather narrow bridge section of the platform. Me think someone got over zealous with safety considerations.
Well we'd better close Wapping then, which is narrow throughout.
And regarding not trusting drivers to stop accurately, for the first 10 years of the Jubilee Line Extension they had to stop manually, to the inch, against the platform edge doors - which in my experience all did faultlessly at every stop.

An 8 car 700 is roughly 5 or 6 metres longer than an 8 car 319 rake, which itself was slightly longer than an 8 car EPB / VEP rake. Is that enough to make a difference at Tulse Hill?
The last coach is almost always hanging off the platform and sometimes an extra set or two of doors are as well

I've had that on a Mk5 set at Leeds Platform 16, of all places. The conductor (a very Mancunian gentleman wearing a massive pair of boots) came rushing through the back carriage saying, "I don't know why it's saying that, you'll be fine, you'll be fine!"

Sdo is set at 6.5 coaches. Signal sighting and clearance is the reason. It may change once the re-signaling is done.
