620 is one of only a few short Tridents which have survived the new decker onslaught, and they may not survive the next Airlink delivery. North bridge on the favourite route for the oldies, the Methadone Express (or the 14 if you prefer)

688 on North Bridge keeps the Marine Trident flag flying in January 2015

625 is another of the small remaining batch of short Tridents at Central, and is definitely a plug on a 29. The driver seemed unimpressed with my undoubted photography skills, so got a cheery wave in return. I'll leave you to guess how the wave into his rear mirror went.
