please empty your brain below

some of this service has been running since late last year, I heard about it during an Open House tour of the KX area. I do voluntary work in Kings Cross, and travel there through Stratford, and they pay for my lunch and fares if any. so I asked if I could now use the new Javelin trains for about £10 a day, but for some reason they refused.
What's the capacity of a Javelin train - do we know?
There's 340 seats apparently, plus 12 tip up seats in the wheelchair area. That's per six car train although two trains can be coupled together.

Obviously that's seated capacity - with people standing it would be a lot more. Let's say 30 people standing in each car, that would be 180 across each 6 car unit - total capacity of 520 people. 30 people is, I suspect, an underestimate of what each car could hold if everyone squeezed in.
may never be busy again? That's very optimistic ;)
There are 29 395s, if the journey has:

5m dwell
6m stp - str
5m dwell
10m stra-ebb
5m dwell (and return)

Then each set takes 26 minutes to do a full service (from moving out of St P, to ready to go back again from Ebbs)

Capacity (inc standing) is 862 per unit according to Hitachi (http://www.railalliance.co.uk/docs/rsl10hitachi.pdf) - doubled up we've got 1,724 per train.

A five minute service interval could be run with 12 trains, so I expect we'll see them all doubled up for the busy times, if not all the time.

20,000 people per direction, per hour - not bad!

Of course Stratford international's outer platforms were built for single flow light international traffic in no rush, not for mass events. Escalators to the platform will be a capacity issue.
jamesup:

that calculation assumes no Javelin services will run beyond Ebbsfleet for the duration - the timetable
http://www.networkrail.co.uk/browse%20documents/eNRT/May12/timetables/Table%20194.pdf
actually shows 8tph to Ebbsfleet, including one continuing to Faversham, and two to Ashford.

The one way trips take 20 minutes (Ebbsfleet), c45 minutes (Ashford) and 75 minutes (Faversham) so, allowing for dwell times, four trains are needed for the Ashford service, three for the Faversham, and four or five for the short Ebbsfleet workings, making twelve trains (24 units).
The challenge will, I'd guess, be getting the throughput of people on to the trains rather than the capacity of each train, especially with that frequency.

I was in Sydney in the 2000 Olympics when a similar shuttle service was running from Central station to the Olympic Park. The queues for the trains were pretty long, but the trains were leaving 2/3rds full, despite the efforts of staff to chivvy everyone on.
Oh that's interesting - I'd read somewhere that 'normal' SE HS1 services were not running assumed that meant just the shuttle would be operating. That eats up a lot of the trains.
