From our UK correspondent Peter Brown:
The Cambridgeshire Guided Busway finally opens [today], Sunday 7th August, and at 25km will overtake Adelaide's O-Bahn (on which it was partly based) as the world's longest guided busway. It will be an 'open' BRT as services will not be restricted solely to the Busway. The guideway consists of two sections. The longest runs from the northern edge of Cambridge to St Ives, while the shorter southern section runs from Cambridge rail station to Trumpington. There are three Park and Ride sites on the route.
The buses are standard UK designs (single and double deckers) fitted with guide wheels. Guideway stops will feature off-bus ticketing. Guideway stop (prior to opening):
Two bus companies (Stagecoach and local independant Whippet Coaches) have signed a partnership agreement with Cambridgeshire County Council for exclusive use of the Busway for 5 years. Services will operate under a single brand - "the busway".
If this busway doesn't turn up significant benefits in customer experience, it will probably be the last, or at least the last to be done with guide-wheels. Adelaide's pioneering O-Bahn is now 25 years old, so one hopes the state of the art has moved on. (There's also a guided busway in Nagoya, Japan, dating from 2001, where the government classifies it as a railway.) All of these, including Cambridge, are open busways, i.e. designed so that buses can run off the ends of the facility onto various street-running lines.
So I'll be curious to see how this goes.
