GWR Aero Propeller Wagon

The Kit


The kit consists of three plates. Plates 1 and 2 are made from thin plywood, Plate 3 is paper. Plates 2 and 3 have a self-adhesive backing to aid construction. Only a few basic tools are required - a sharp craft knife, wet 'n' dry sandpaper, a small file, tweezers, and a small drill. Most glues can be used to join the parts such as balsa cement, PVA, superglue and two part epoxy. A small amount of liquid polystyrene cement is required for the chassis. The model rides on the proven Peco NR-121 10ft WB Chassis (steel type solebars) which requires slight modification.

The fascinating scene below was created as a diorama by Carlos Briz. The three-bladed propellers carried by the Aero wagon would have been the kind used by the Lancaster bomber.

Prototype History


Two-bladed propellers for early airplanes could easily be transported in normal open wagons, however, by the late 1930s, three-bladed propellers with adjustable-pitch attachments in the bosses had been developed. Therefore, the GWR issued diagram E4 and built five wagons in 1938 for the special purpose of carrying these awkward loads, described as 'wagons for three-bladed air screws with trestles and aperture in the floor'. Perhaps unsurprisingly, a further 170 were built during the early years of the Second World War. They received the telegraphic codename 'AERO' after 1942. The wagons were basically standard O32 open wagon underframes with a complete overall deck apart from an aperture to take the two crates that could be carried.

The end of the war and the subsequent development of commercial jet engines reduced the manufacture of airplane propellers and hence the need for these wagons; most had been converted to their original design as simple open wagons by the early 1950s.
