As previously advised, from 15 December, there is a major overall of rail operations between Paddington and Reading, when TfL take over approximately half of local services on the main lines.
Local rail user community group, Henley Trains have worked with Great Western Railway to ensure that all peak commuter services remain broadly as before, with fast GWR-to-GWR connecting services.
However, local users are warned that most returning fast evening peak GWR services will NOT be available to those on off-peak tickets. Off-peak ticket holders will need to take the slower TfL services, which will not be timed for optimum connections at Twyford, and journey times are likely to be extended.
GWR have made a table below of where off peak tickets are valid and related journey times. Note that tickets are valid again on fast trains from 1849 onwards.
Please note that there are fare benefits for those with under 12s taking only TfL trains between Twyford and London. 5-11s will still need tickets on the Henley branch.
This is a complex topic and Henley Trains will be happy to help with questions or to share GWR’s explanation. They can be contacted at firstname.lastname@example.org or on Twitter @Henleytrains.
