Question to the Department for Transport:

To ask the Secretary of State for Transport, if her Department will take steps to (a) increase (i) frequency and (ii) reliability and (b) decarbonise services on (A) the Henley branch line and (B) other branch lines.

The Department and operators continually review demand when assessing the need to increase frequency going forward. There are currently no plans to increase frequency on the Henley line. The Department also monitors reliability closely as operational performance is a key focus for the Secretary of State. Great Western Railway is developing plans that would decarbonise services on branch lines in the Thames Valley and these are currently being discussed with the Department.
