Marylebone Wall Siding

[MerlinRail 804]

Does anyone know the length (m) of Marylebone wall siding? Aka how many 23m coaches could fit? Am I right in saying it extends beyond the end of platform 1 or not? Thanks!

Also, how many seperate trains can be signalled into the siding?

Its about 275m long. Probably needs some stand back from the ground signal. You should be able to get 10 coaches in. No idea if its permissive but it doesn't have a main aspect into it.

275 / 23m coaches gives 11.9 ish, so surely you could squeeze in an 11th?

This 'wall siding' has long seemed to me a 'waste' in relation to today's needs. Would the disruption be worth it if it were to become a platform line, with consequential rejiggings of current platforms? I'm not up to drawing a adiagram of this but hope that most imaginations are ... Perhaps the answer might be different if heading to a four track approach?

If you shifted everything to the west by one tracks width then you could probably plop a platform 0 in where the wall siding is. P6 would probably be shortened a bit though

I think you’d then have problems with the position of the roof piers, they’d be far too near the platform 2 and 4 edges. I’d be surprised if it hadn’t been investigated and ruled out before.

If you look at an aerial view, the eastern main roof is not as wide as the western side, there’s less overall room to play with.

It takes 11 cars according to Chiltern's operational instructions.

Originally the Great Central Railway intended to expand the station later, but didn't want to initially buy up lots of homes as their London extension was using lots of funds (of course not a new problem, think HS2 station at Euston) . Hence why concourse seems off centre.

If you look at this old plan (sorry couldn't find better link) the passenger station is the yellow bit, can clearly see where next block of platforms would go after demolishing the homes (which in more recent times got knocked down and replaced by office building for BNP Paribas Bank). If First World War hadn't happened and railway got richer then might have had platforms in bigger station right through to Harewood Avenue.

They also left a longer term option to buy up Boston Place (the road with older homes behind the wall) and add 2 or 3 platforms there. However the approach north of Rossmore Road bridge that used to be railway land is now built over (apartment blocks called Palgrave Gardens)

I actually learnt something completely new looking at that old plan, never new there were lines passing under Lisson Grove in area where Capland Street is now

Last time I was in Lisson Grove there was still a bridge there over what I believe used to be a carriage servicing area with a traverser for cutting out coaches. The base of the wall of the GCR goods depot was still in place nearby.

Would it be worth having 2 half-length platforms - building out over the buffer-stop end of 1 to create 0 - rather as was done at Nottingham a few years ago?
You would need to extend 6 at the country end too.
Would that be operationally worth-while?

That has been considered in the past and rejected.

Whilst it certainly wouldn't be ideal for passengers as it would require quite a long walk, could you not easily fit a seventh platform north of Rossmore Road?

Maybe you’d need a second entrance or an underground travelator thingy or something from the tube
