There is a discussion about the potential impact of the West London Orbital line on level crossings in the area on ChiswickW4.com in which the following document was shared. This dates back quite some time but the project seems to be gaining momentum so it might be worth bearing in mind again. The Churchfield Road crossing would be considered for closure with a footbridge and ramp being installed. Closure isn't necessarily going to happen but, if it doesn't there will be very long queues up and down Churchfield Road.
