The Blackpool system was the first electric tramway in the UK and, until the recent reintroduction of trams to major cities, the last. The pantographs are relatively new, when I was younger they still used trolley poles. Blackpool is one of the largest of not the largest seaside resort in the UK and was popular with the workers from the industrial centres of the NW. The tramway now runs fom the southern border of Blackpool on its own trackway on the promenade. To the north it has its own reservation away from the prom until it gets to the Town of Fleetwood where it runs in the street. Fleetwood is a ferry port for Ireland and used to have a major fishing fleet as well as docks. The trackage internal to Blackpool town itself has been long gone
At the end of the season the Blackpool prom is lit up with fancy lights, the 'Illuminations', which are best viewed from a double deck tram. The tram fleet also includes illuminated tramcars, I remember there being one tricked out as a space rocket, and another as a US 'Western' Locomotive. See...
A number of odd designs have been used including open single deck cars, but probably the strangest was the old double deck 'Dreadnought' Car. Each end had two sets of stairs to the top, either siide of the motorman's central cabin> See...

I believe the idea was to facilitate fast loading and unloading. I believe the name came from the resemblance of the front to the bows of the old 'Dreadnought' Battleships.
There was also a steeple cab loco used to move coal wagons along the tramway, to a facility at Thornton's Gate.
Hope that this is of interest.
