These wagons have been meticulously recreated, and make a fantastic addition to any model industrial or preservation collection.

The first prototype Merry Go Round Wagon (HAA) No. 350000 was built in Darlington in 1964. It was preserved to become part of the National Collection in October 1995.

In total 10,702 production wagons were built at Shildon Works before its closure in 1984 whilst the remaining 160 wagons were built at Ashford Works in the Southern Region. The Friends of the National Railway Museum North East Branch, who are based at Locomotion in Shildon, purchased the last Merry Go Round Wagon (HDA) No. 368459 in late November 2010.

Under the TOPS (Total Operations Processing System) coding system introduced in the 1970s these wagons were classified as HAA wagons and initially carried B numbers when working between colliery and power station. The wagons are a reminder of this era when coal was delivered in "Merry go Round" fashion from collieries to power stations. They enabled automatic loading and unloading on a continuous cycle as collieries and power stations were usually fitted with dumbbell loops to aid the process undertaken at crawling speed. These 32ton wagons could run at 45 mph loaded and 55 mph empty. HDA No.368459 wagon covered just under 1,000,000 miles during its working life, it is a fitting tribute to the craftsmanship of the workforce at the works.

Both the first and the last MGR wagons are now preserved as part of the national collection, and can be seen in NEW HALL at the Locomotion museum in Shildon.
