This shot from October 1982 typifies the operation of the period. Former Huddersfield Seddon 4040, by now in MetroBus livery, has cleared the summit. The two-track number blinds used by both Halifax and Huddersfield were fine when they were separate undertakings but were not best suited to the larger service numbers that came with a county-wide numbering system. Two digits have had to squeeze into a small aperture and it was a reluctance to do this that meant routes in Halifax and Huddersfield were renumbered relatively late.
