Three wagons were constructed by Railway Workshops between 1953-54. Coded LLW and numbered 130, 590 and 750. These 46’ long depressed centre well wagons were designed to carry heavy and over height loads. Originally delivered with plain bearing bogies and buffers, later they received roller bearing bogies and had their buffers removed. They could carry loads up to 50 tonnes distributed over the bogies or up to 38 tonnes distributed over the well section. Their versatility ensured they remained available for traffic until well into the 1990s.
