This year marks the 50th anniversary of the Progress Twin Car. From a prototype set built in 1958, through to the conversion of ten 1930s-built Railcoaches and ten brand new Trailers in the early 1960s, Blackpool's Twin cars have graced the promenade and Fleetwood route for five decades.

With the remaining sets sold early in 2010, final withdrawal from service is now confirmed for November 2011. This 80-page hardback book tells the story of these tramcars.

From the rebuilding in the 1960s, the new Trailers, all cream livery, the 1970s, Circular tours, the 1980s, Market day specials, new liveries in the 1990s and the Metro colours of the 21st century these iconic and unique tramcars have gained their place in Blackpool's history.

Using mostly previously unseen black and white and colour images, many in full page format, this is their story.

This is the first in a new series of books written by local Blackpool tram enthusiasts. The book is presented in the same format as Blackpool Trams Pictorial No.4 and the series is edited by Nick Meskell.
