Unlimited off-peak travel for one day between Moreton-in-Marsh and Oxford; between Ashchurch for Tewkesbury and Yate; and between Gloucester and Swindon via Stroud - these lines are obviously not all connected.
The ticket is also valid and can be bought from Johnson’s Excelbus and Stagecoach buses within the Cotswolds Area of Outstanding Natural Beauty which connects the two separate rail lines.
