Recently a pair of wagons, former National Rail wagons, of which 50 were built by China Northern at Qiqihar appear to have been placed in a siding.
The wagon structure has failed at the side sills where they cross the slope sheet at the end of the hopper.
These are the earlier version of the CNR type C-35 hopper which lack a continuous centre sill which places greater stresses on the side sill although end struts are provided to transfer some traction forces into the top rail.
The failure is reminiscent of the failure of QR VAO aluminium coal wagons in the 1970s, although they carried half the load of these Hunter Valley wagons.
The design is similar in some ways to the UGL NHPH and NHQH wagons that are being progressively replaced due to cracking of the stainless steel. The Chinese wagons are mild steel, however.
The large batch of 176 NHWH wagons from Qiqihar were to a revised design with a centre sill so may not be affected by this failure.
