The TTA tanker was a mainstay of cargo traffic in the latter half of the 20th century. The TTA tanker was not a specific design, but had a specification which resulted in largely similar wagons from each company that made them. Initially designed to haul dangerous cargo such as fuel, the use of the wagons diversified as they came closer to withdrawal in the early 2000s. 

This triple pack of three TTA wagons are all decorated in detail carrying the eye-catching BP livery in green. Each wagon has a detailed gantry on the top with ladders, sprung buffers and different running numbers to create an accurate rake.
