Not sure where the BBC get the idea it's on Friday, as this is part of the ORR response to the Strategic Business Plan released today, just like the Cotswold Line stuff.
Should anyone wish to peruse all 374 pages of it, see
http://www.rail-reg.gov.uk/upload/pdf/368.pdfThe Redditch branch and Bromsgrove electrification are on pages 160-161, and are listed as "Other schemes with strong business cases driven by revenue benefits".
Cotswold Line is mentioned on page 159 and 360.
There are tables near the bottom giving suggested budgets for enhancements etc, with what NR estimates and what ORR recommends.
