The TTA wagon was developed in the 1960s and continued in production through into the 1970s. The wagons were built by a variety of companies, this, as well as the many variations and changes to the body and the chassis through the lifespan of the wagons created many variations and were removed from service in the early 2000s. The wagons were originally built to haul petrochemical products across the country. Many wagons were repurposed later in life to carry a variety of other products including Caustic Soda and Calcium Carbonate slurry. Dapol will initially be modelling the 45T version with two body types which will allow Type A and Type B tankers to be produced. Other versions of this wagon will follow in later production runs.
