The NQR class of trucks were the staple of the Victorian Railways' narrow gauge fleet. 218 examples were constructed between 1898 and 1914, designed as an open wagon with removable end panels as well as three drop-down but removable doors either side. When assembled into the open wagon format these wagons were designed to have the same capacity (weight and volume) as a normal broad gauge four-wheel open truck, to make load transferring easier at the interchange stations—
Colac,
Wangaratta,
Upper Ferntree Gully and
Moe. The goods truck code had been derived from the conceptually similar broad-gauge
QR trucks, which had removable sides to permit various types of loading. Previously, "Q" had been used for bogie flat wagons and "R" for bogie open trucks. Some of the original trucks were apparently provided with end sliding doors and three trapdoors in the floors, but these elements were not retained in future builds; Over the years, a number of NQRs were provided with removable wood and steel frameworks with canvas roof canopies and side curtains, and internal seating to supplement the rest of the passenger stock during busy holiday periods. Vehicles known to have been so-fitted include 86NQ On 9 September 1954 six NQ wagons, nos 94, 100, 102, 153, 169 and 208, were sold from Moe station to the Forests Commission. Coincidentally, the quantity of six wagons matches the number taken from Gould station to Moe after the last official train operated on 25 June 1954; the transfer was made by engine 7A and van 7NBC on 29 June 1954. In 1965 the Victorian Railways transferred a set of two NC vans, three NU wagons and four NQ wagons, one of which (NQ149) was fitted with a water tank, to Upper Ferntree Gully, from which they were handed over to the Preservation Society, in order to assist with the extension and reopening to Emerald station. In goods service are NQR wagons 21, 29, 91, 186 and 216 with a capacity of and a tare weight of ; It was rated as weighing when empty, or when full. This vehicle has a tare weight of and a loading capacity of ,
Current fleet The Railway also possesses untraffickable trucks: NQ 19 is configured for pulpwood, and open NQRs 59, 92, 103, 125, 142, 151, 153 and 203. There are also five off-register NQR wagons, numbers 23, 26, 94, 110 and 169. Additionally, the latter document notes that NQR87 was owned by "Shires and Councils" as a general category rather than any one specifically, and that plenty of underframe exchanges have happened between rolling stock used on the Puffing Billy Railway. According to that, the underframes of NQR100 and NQR208, privately owned, were used in the construction of 21NBH and 20NBH respectively, and many other vehicles have had their underframes swapped or transplanted at various times.
