The English Electric Balloon is a type of double-decker tram that is operated on the Blackpool Tramway. Initially brought into service in 1934, the Balloon formed the backbone of the Blackpool tram fleet until the tramway's conversion to a modern light rail network in 2012. Following the network's re-opening, nine Balloons were converted to meet the disability regulations to serve as a supplement to the modern Flexity 2 vehicles. Some of the Balloons have been retained for use within the heritage fleet, although their use was temporarily suspended in December 2024.
