Before the ubiquitous Tridents there were the Atlanteans. Replacing the equally large fleet of open platform PD3s from 1977 under a step change introduced by Derek Hyde, the Leyland Atlanteans were the mainstream of Blackpool services.
Seeing two examples operating in the town (at least over the weekend) brought
back memories from an era pre-dating even the new Centenary cars from 1984.
Note the different livery styles with the later version immediately above parked outside the Transport offices during the Open Day weekend. This was a privately preserved vehicle.
