Built in 1995 for National Power, the JMA wagon started off life transporting coal to Drax Power Station but it wasn't long before they started being transferred to other workings such as aggregate. Until 2014, they soldiered on in their original National Power livery but following a shortage of wagons, DB Schenker decided to enter them into a refurbishment project where they were reclassified as HKAs and outshopped in the striking red livery.
