The local services west of Paddington (through Ealing Broadway to Heathrow/Slough and beyond) currently receive a pretty poor service in comparison to many routes in other areas of London. Most services are currently 2-6 car turbos (46-138m length) with fairly low frequency (4tph West Ealing, 2tph Hanwell, 6tph at Southall, etc).
Electrification and Crossrail are set to drastically change the situation. The turbos will be replaced 200m class 345s and instead of stopping at Paddington the route will continue through main employment areas of central London. With all the hype around Crossrail, its easy to miss the fact that although trains will be longer the frequency at many stations will not be "tube-like". Ealing Broadway, Southall and Hayes & Harlington will see 10/8tph peak/off-peak but stations like West Ealing and Hanwell will be limited to 4tph all day.
Based on 2015 data, West Ealing and Hanwell had less than 1 million entries/exits per year:
However, underground stations within 2 miles of them had 2-4m entries/exits:
These parts of the Central/Piccadilly line have 13tph peak with 130m/106m length trains respectively.
The areas surrounding West Ealing and Hanwell have a similar population density to the underground stations two miles away. It seems likely that once people adjust to the new service available, usage at these stations is going to increase substantially. Will the Crossrail service be able to handle this suppressed demand? Maybe the demand will be self-managing with people who are unable to board Crossrail or put-off by the low frequency of service reverting to buses/etc to get to Ealing Broadway or the Central/Piccadilly lines for a more frequent service?
If Crossrail usage west of Paddington does exceed the capacity available from the 10tph planned, are there any measures that could be made with the existing infrastructure to send more than 10tph past Paddington/Westbourne Park?
If capacity does become a problem, the most obvious thing seems to switch the Heathrow Express paths to Crossrail once the usage rights expire and move them to the relief lines stopping all/most stations between Heathrow/Hayes & Harlington and Paddington in place of the residual GWR "slow" services to Oxford/etc that currently run on the reliefs to the mains (making them non-stop until after Heathrow Junction). Is that feasible? What else could be done?
