Australian Wagon Physics E-Spec for Roller Bearing Wagon Stock Cars.
Best on 22-24 ton Cars Unloaded Tare Weight and upto 91 tons loaded, anything lighter or heavier makes it handle different the physic has been set up with Grade Control and NSW style chokes so the brake cylinders vent at a very slow rate, the brake ratio is also based on Load Compensating System which means the values are set for a fully loaded wagon's max braking effort, only issue is unloaded wagons will brake too hard, The Load Compensating Lever reduces the max brake cylinder pressure to 27PSI for unloaded wagons while loaded wagons get the full 50 PSI pressure, hopefully one day N3V puts a brake cylinder efficiency tag in the scripts so we can control it for loaded or unloaded wagons.
Simply modified to better represent heavier grain wagons than Azervich had built these great especs for, and to extend the length of the choke for running heavy wagons down the Illawarra Mountains. Best suited to modern, Chinese built wagons with very slow releasing chokes, such as the BGTY/SGMYs.
Brake Pipe: 72PSI Max
Brake Cylinders: (2x) 12in x 12in 50 PSI Max
