It's light during the day, but you obviously don't see it at 8'oclock in the morning when there's noses pressed against the glass going towards Benton and the Freeman!
When the 18 ran to Four Lane Ends in the mornings they used a decker which dropped onto one of the first Buddle Road 1's. It's justified deckers at peak times, but must be more beneficial to fully allocate rather than interwork further boards.
