AV Dining Car - Under Floor Detail

Underneath the AV Dining Car is another subject of interest, so here is what I found for completion of my model of the AV whilst on a visit to the ARHS Museum.

Essentially the detail underneath the Dining car is symmetrically balanced consisting of 4 Battery Boxes, 2 Water Tanks and 2 sets of Brake Gear.

In S scale measurements, Battery Boxes are 37mm long and can be purchased from Railwest as their "Long" battery box. The Water Tanks are 28mm long and can be made from a section of 7.9mm Evergreen tube #230 with some #100 strip for the support straps. Railwest also supply Vacuum cylinders and V hangers to suit.

The Battery Boxes and Water Tanks should all fit within the cast areas of the frames . The Water Tanks should be positioned with one end against the center frame casting and hang with 5.5mm of tank exposed/visible below the sole bars.
 
V hangers should be mounted on the external surface of the outside frame with the inside V on the inside frame 2/3rds over the center of the carriage frame. Vacuum cylinders are a close fit to the V hangers with a distance of 7mm between the cross bar and center of the cylinder.
Brake Gear  & V Hangers
The older style carriage Queen posts are also available from Railwest as is .7mm brass rod for the tension bars.

With any luck this information combined with the roof detail information, will enable completion of a few more models of the AV Dining Cars.
