Will all trains on the GWML need to stop at Old Oak Common?

[Annetts key]

I often think that people don't fully grasp the performance modern multiple unit trains are capable of.

We are certainly not in the loco hauled era any longer.

Careful with your generalised implied comparisons. I’ve certainly been on loco hauled stock that was quicker in accelerating compared to a DMU. And yes, modern trains do have better performance compared to older designs.

However, the type of traction is only one element here. Far more significant in my humble opinion is the planned dwell time compared to how long it actually takes the passengers to alight/board.

I’ve seen plenty of trains loosing time due to the actual station duties taking longer than the timetabled dwell time.

Whereas, the only time that I have noticed any significant loss of time due to train performance, is when the traction has a fault. Such as part of a multiple unit having engine/drive problems, a HST having one power car unable to produce traction, or similar.

Or when a train is formed of a multiple unit or locomotive and stock that has significantly different (as in lower) maximum speed, for example when a 90 MPH DMU has been substituted for a 125 MPH HST or 80X train.

I’m not sure a simple count of entry / exit foot fall at a station like Paddington is particularly enlightening.

Paddington now has many entrances/exits. Two London Underground stations (It’s rather uncommon for me to use the larger one at the city end). Certainly, a significant number of passengers use both tube stations, for onward travel elsewhere in or around London.

I presume that this survey must have actually stopped passengers and asked them questions. Otherwise how could it be determined if people were using “onward forms of travel”.

So you would need rather a lot of people to actually monitor the flows of people, or to ask them questions.

Euston I know less well. Mainly because although I often have entered the main entrance, I’m either only using the underground station, or am simply passing through (due to the HS2 works preventing me from using my normal route). In fact, I think I have only used a train from their once.

Oh, and what do people class as ‘with in walking distance’? I’ve walked to Euston from Paddington in the past. It’s not that far really.

I walk fairly often from Paddington/Marylebone to the Wellcome Institute and I wouldn't want to walk that with lots of luggage.

Equally, I probably would walk from Paddington to Marylebone (based purely on distance: in real life I wouldn't walk it because I like the excuse to use the Bakerloo line) or Lancaster Gate or Marble Arch coach stop with luggage.

So I guess for me it's up to about a mile.

Something which I don't think anyone here has pointed out yet is that there isn't the capacity at OOC to run some through and some stopping services, as highlighted in the acceptance letter to Grand Union last week.

What acceptance letter is that? On this forum it’s consistently said that stopping everything gives higher capacity than mixing in some through services.

Yes, but that matches the post you are quoting. There is insufficient capacity for a mixture of through and stopping services, but the higher capacity enabled by stopping everything makes it fit

I’m not suggesting walking that far if you have luggage. Or indeed if you have limited time. I was just saying that if you have the time, don’t have much to carry, and don’t mind walking, it is possible.

Generally, 500m is the most transport planners believe people will generally walk to access public transport. It's used in designing urban networks.

Sometimes they say 500m for a bus stop but 800m for rail.

Why are the 8 conventional platforms 250m when a 5+5 IET is 260m, or does this mean won't be able to call ?

Platforms will accommodate 5+5 IET. Track and S&C design starting imminently.

I am confused, perhaps the diagram is wrong ?. Are not the 810s shorter so as to be able to fit the 260m platforms at StPancras ?. So the longer bodied IETs must demand more then 260m ?.

The figures in the diagram are rounded. The specific lengths could easily be 265/270m. HS2's website says the HS2 platforms will be 450m long, but the diagram says 400m: https://www.hs2.org.uk/building-hs2...ommon is a,fit 6,300 Routemaster buses inside.

Six 450m HS2 platforms will be built in the 850m-long underground box,

Platforms 1-4 at St Pancras can only take 240m trains, as I understand it. Which is the reason why 810s are shorter

 

[stuu]

The GWML platforms at OOC are 275m long on the planning documents; HS2 platforms are 415m long

Ah, my bad memory then thinking StPancras was short at 260m.
