VR C Class E-spec - 1 (TS12 SP1)

When built, the C class were the most powerful locos in Australia. They were VR's main heavy goods locos until the arrival of the X class. They where also poor performing on the long grades as the fireman couldn't keep up with the shoveling and would run out of steam. The entire class was converted to oil burners beginning August 1946. They had a #4 brake and straight air brake. It is believed that the Taradale and Mooroobool viaducts were strengthened to enable the operation of these heavier locos. C 5 was the first VR loco fitted with a modified front end in May 1933. This modification became a standard upgrade on the A2, X, S, K, N classes. C5 was the first VR loco with a cross compound air compressor Jan 1929. They had a load capacity of 554 Tons on the 1in50 Grade and 1333 Tons on the 1in100 Grade at 80% Boiler Pressure.

Max speed increased from 50 to 60MPH for WWII passenger work, 'German pattern' smoke deflectors were added starting with C 22 in June 1948.

Read The Following, The physic will perform properly if the following is done. When running at high speeds use 25% cut-off and a regulator of 60% to 100%, 60% will slowly raise the boiler pressure, 70% will slowly lower the boiler pressure, Do not use 100% regulator at slow speeds unless you are climbing grades at a speed of 13-18mph and using cut-off 25%, The cylinder settings have been set to produce correct Tractive Effort at 80% boiler pressure (160PSI), trainz is over powered between 30PSI to 150 PSI Cylinder Pressure, however when you pass 160PSI the tractive effort drops just slightly and doesn't quite match the prototype for 85% boiler pressure (170PSI), so it is okay to run between 150PSI to 170PSI boiler pressure.
