Newly arrived at Stagecoach Devon is 53616 KX58NCO which was formerly with Stagecoach in Cambridge. It carries the new livery for the X1 Plymouth - Tavistock Express service and is due to enter service today. It is one of three which have arrived, one more in this livery with another in standard livery.
The decision to go with coaches for the X1 is due to the road works along the Outland Road/ Derriford corridor which has resulted in significantly increased journey times meaning that under European legislation (based on the average journey time for passengers on any route being more than 90 minutes) toilets are now required. They looked at fitting toilets into standard Enviro double deckers but it was not economically feasible. The other Tavistock service (service 1) will retain standard buses for now as most passengers use that for the shorter local journeys so do not need toilet facilities under this legislation. It also gives the company more space for less mobile passengers who will be encouraged to use the 1 rather than the X1 for the time being. This is very much a stop gap solution whilst the road works are in progress although this could be up to two years. If journey times fall significantly then they can revert back to standard buses.
It is also hoped that as Brexit takes shape and UK Government starts to scrap the EU rules which protect passengers and staff that the company wont have to worry about passenger comfort and welfare as much. As the current UK Government has shown no interest in bus passengers in the past companies are not expecting much in the way of new legislation to hamper their businesses.
