Indeed, but in terms of passenger numbers v 2015 Birmingham only operated for the three quieter months at the start of the year this year whereas next year it's scheduled for nine months including the summer season so should carry far more passengers in 2016.
In terms of frequencies I wonder will these services really operate six times a week throughout or will it be more a case of 'up to' six services a week with lower capacity in the winter. Certainly I'd be amazed if Edinburgh ran six days a week all year, that frequency could work in the summer but three a week would probably be plenty at this time of year.
