If the 2tph to terminal 5 only stops at ealing broadway.that will kill the heathrow express. . i thought the plan was that that between Hayes and paddington each train will have a stopping pattern that allows a 16 minute travel time between Hayes and Paddington. With each branch missing out a certain number of stops to achieve that . the terminal 4 trains are not going to be an all station stopper because of the freight trains
Londonist has got the 'how many trains stop at this station' right, but whether their other assumptions are correct is a different matter.
They assume that services are either all-day or peak-only, rather than their being different calls off-peak than peak. They also assume that there would be an even and consistent London service to/from West Drayton with the same stopping patterns.
As such, interesting solutions (eg the 2tph that skip H&H not necessarily being the 2tph that skip Southall, or the 2tph additional peak stops at Ealing Broadway, Southall, H&H, Iver, Slough, Burnham, Taplow, Maidenhead, Twyford and Reading not necessarily being on the same service) don't exist.
I think 4tph T4-T23-H&H-Southall-Hanwell-Ealing Bdwy-Acton ML-Paddington can be safely penned in. However, while they will all go to Abbey Wood at peak times, off-peak 2tph will go to Shenfield in order to keep even 15-minute headways at Heathrow, and even 6-minute headways on the eastern branches.
How's this for west of Paddington? It's not perfect, but it's a little bit more even in the stop-skipping.
