I have just noticed from the timetable that the bus service departing 11:17 Wednesday from West Ealing to West Ruislip is listed as a "service bus", instead of a rail replacement bus.
To my understanding, the term "service bus" is used on public bus services, which are not part of National Rail but are included in the National Rail timetable, mainly because there are through ticketing, for example, RailAir services.
Why isn't this West Ealing to West Ruislip bus a rail replacement bus instead?
Because there is NO 'rail' service between West Ealing and West Ruislip; it's rail from West Ealing to Greenford, then a 'Central Line 'tube' Greenford to West Ruislip?
Probably because it’s a LTP permanent bus, much like the 99 from Tilbury Town to Tilbury Riverside rather than an STP rail replacement bus.
What are LTP and STP please?
I think maybe some different 'issues' have got caught up in this thread. What has got it started just now?
There was a bus run over part to 'replace' the former North-South service that had run via Kensington Olympia between Manchester and Brighton/ Dover (variations over time); and a 'parliamantary' train betwewen West Ruislip/ High Wycombe and Paddington when the service to Paddington was 'diverted' to Marylebone.
The value (social or otherwise) of the West Ealing to Greenford service is another matter, which I imagine was considered at the time of 'cutting back to a bay platform at West Ealing when the Elizabeth Line was conceived.
Crayonists would have been attracted to the possibility of linking the West Ruislip and Ealing Broadway branches of the Central Line via a loop superseding the existing 'rail' line.
'Regular' TfL buses connect Ealing Broadway and West Ealing with Greenford Broadway (passing the intermediate stations at some distance) and thence to Ruislip (not that close to South Ruislip or West Ruislip); a change of bus is required at Greenford Broadway to reach Greenford Station.
Not sure I'm helping- just what is the issue/ problem?
