A joint venture between Scottish Citylink and Megabus led to co-ordination of services in Scotland. On 21 November 2005, the 900 Motorvator service was replaced by an enhanced Citylink service, with the facility to buy seats through the Megabus website was retained. The next week, most of the faster Citylink services between Aberdeen, Dundee, Perth and Glasgow, and Inverness, Perth and Edinburgh were replaced by a more frequent, combined Megabus/Citylink service. As a consequence, passengers who previously used parallel Citylink services from the bus station in Perth town centre were required to use Broxden Park & Ride on the outskirts of the town, with little to no onward connections to the town centre. Tickets for the combined Megabus/Citylink services are available through both companies' websites, though often at different prices. From 16 February 2006, the slower Citylink service between Dundee, Perth and Glasgow became available to book through the Megabus website, restoring Perth bus station to the Megabus network. The same day of the Citylink service modifications, the London to Manchester route was extended to Preston, with some journeys extended to Blackpool or Lancaster. This coincided with the loss of National Express work at Preston depot. The extensions to Blackpool and Lancaster were short lived, and were withdrawn in February 2006, citing low passenger numbers. Following this Megabus tickets were sold on the Stagecoach in Lancashire X61 Blackpool to Manchester service, which was usually operated by a coach but this service was significantly slower than the equivalent National Express service. Again following the loss of National Express contracts (this time at Stagecoach Warwickshire's Rugby depot), on 5 December 2005, the London to Birmingham service was increased in frequency to every two hours with an additional stop on the outskirts of Coventry, and the withdrawal of the direct once-a-day service to Coventry city centre. One journey a day in each direction was extended to Wolverhampton. The stops in the south of Birmingham were no longer served. Further changes on this day were the doubling of the London to Nottingham service to twice a day with one journey extended to Chesterfield (which regained the service lost in April 2005) and the introduction of a new once-daily service from London to Norwich. 2006 to 2009 A number of changes to routes were made on 27 March 2006. A direct service was introduced between Ferrytoll Park & Ride in Fife, Edinburgh and London via
