The concept was proven to work and ten trailers were ordered from Metro Cammell of Birmingham - by then the main supplier of bus bodies to Blackpool (as illustrated by our PD2 and PD3 buses). These arrived between July 1960 and January 1961 as T1 to T10 - with T6 arriving on 14 November 1960. Meanwhile Blackpool Corporation converted eight more Railcoaches to motor cars and refitted 275 with controllers and motors. This process took a bit longer with the last car not finished until 1962.

Initially the first few motor cars could be seen with any trailer. The weakness of the concept was the lack of flexibility as the cars had to turn on one of the four loops (Starr Gate, Pleasure Beach, Little Bispham and Fleetwood). In 1962 set 281/T1 was rebuilt with a cab in the trailer and became a 'permanently coupled' set, the motor sacrificing one cab for its trailer. A further six sets were permanently coupled with 276/T6 being modified in 1969 (by this time renumbered 676/686). 

The work to 676 in 1969 was quite extensive as the prototype pair did not have quite as extensive an overhaul as the later cars. The sliding roof was removed and the roof windows rubber mounted - as the production cars had and uniquely for a twin car it received plastic ceiling panels. Work took from April to August and the set returned to use for the Illuminations with only the motor car painted green and cream- the trailer staying cream until the end of the season. 

The set then settled into routine but humdrum high season work. By 1990 the seven surviving sets were looking rather tatty - most not having been repainted since the 1960s or 1970s. A refresh took place with a new livery of green roof, skirt and doors adopted and all seven motor cars having their trolleys replaced by pantographs. 676 and 686 were the fifth set to be treated and although 676 was painted in August 1991, 686 was not finished until October so the set missed the entire 1991 season. 

Another break saw 676+686 miss the 2001 season but emerged in 2002 with a fresh set of trucks - that season ended on a high in  October 2002 when a sudden ban on double deck cars on the northern section of the tramway due to track defects saw all seven twin sets drafted onto Fleetwood service on 18 October - then an extremely rare occurrence. 5 sets had further overhauls in 2003/4 but 676+686 missed out and on 23 October 2004 operated for the last time on tram specials, prior to withdrawal at the end of the season. In February 2010 the set was secured for preservation by LTT to return to its summer 1970 condition.
