I am travelling to Penzance from Trowbridge tomorrow morning, booked on the 0954 to Westbury thence on the 1009 to Plymouth. None of the journey planners are now showing this. The service from Westbury is the diverted and retimed 0903 from Paddington. Realtime trains shows this as operating to its normal schedule via Newbury. Open train times will not show any departures from Westbury tomorrow morning. Is my service still operating? Any advice?
I've looked at real time trains ... yes, shows 12:20 as first train off Westbury to me. Odd, bearing in mind PhilE's post
Is your ticket Advance? If not, I would be tempted to go via Bristol and Cross Country to avoid being left stranded for hours.
Would also ask on Twitter, Facebook, call National Rail and see if they give you consistent or conflicting answers.
