Using one of the tickets I was given at the Trentbarton focus group last month, I rode Skylink Derby. As this Trentbarton line is joint-operated between them and Kinchbus, the MANGO cards are not used on this service and so it has not been, until today, a route I had explored.
Skylink Derby begins in Derby (obviously), goes to East Midlands Airport as Skylinks Nottingham and Express do, through Loughborough and all the way to Leicester. I travelled all the way to Leicester and walked around the centre there for a short time. This marked the first time I can recall of my stepping foot in Leicester during the daytime, rather than past midnight. Most of my experience with Leicester comes via travelling through it rather than walking around it.
As for Skylink Derby, it's a fun route; it's long and there's plenty of scenery to observe while riding it. Also, as a result of riding Skylink Derby and using it to travel to Leicester, I have visited all of the outer regions of the Trentbarton network, as viewed here (map is outdated as it shows the defunct Radcliffe Line and Ruddington Connection and doesn't show Skylink Express but nevertheless shows the distant points of the network).
