Plusbus is a cheap bus pass (like a travelcard) that you buy with your train ticket at any station ticket office, by 'phone or online. It gives you bus travel to and from the rail station and around the whole urban area of town that's at the start and/or finish of your train journey.
Across Britain over 200 bus companies accept Plusbus tickets for travel on their services and they can also be used for travel on trams in Birmingham, Nottingham, Sheffield and Wolverhampton. Adult ticket prices start from £2.00 and Railcard holders get one-third off the price of PlusBus day tickets. Visit the Plusbus website here to find out more information.
