Merchant Navy Class 4-6-2 no 35028 Clan Line is hauling a non VSOE train to Bristol on Saturday and should arrive at 13.06.
It runs via Berks and Hants line then along the Avon Valley to Bathampton, Bath and Bristol. The return is via Bath and Salisbury.

I don't know if the arrival times will be altered but the train is likely to be diverted due to a collapsed bridge near Feltham.
