VR Y & RY Class E-spec - 2 (TS09)

This enginespec is for the Victorian Railways Y Class and RY Class Locomotive built Pheonix Foundry and Robison Bros South Melbourne after reboilering to 175PSI Larger Boilers between 1904 to 1908. During 1924 some where equiped with Duel Westinghouse Pumps with Larger diamter air pipes and Shunter's Boards on both Locomotive and Tender, some that where used on Suburban goods/passenger only had Tender Shunter's Boards.

This e-spec is setup with the Duel C & CC Class Westinghouse Pump, This physic is set to keep the boiler pressure high as the locomotive was mostly used on heavy goods around Melbourne, Newport, Geelong, Ballarat, Ararat and where sometimes used for banking on the 1in52 to 1in48 Grades as the reboilering gave them 25% more tractive effort compared to the earlier 140 PSI rated at 17,472lbs tractive effort, they where also used on extra passenger trains till early 1920s as the Surburban lines had rather steep grades. The newer Tait Cars and Swing Doors being too heavy for the 2-4-2 and 4-4-2 Tanks leaving only the DDE and Y Class.

UPDATED 07-01-2015: 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 70%, 60% will slowly raise the boiler pressure, 70% will slowly lower the boiler pressure, Do not use 100% regulator unless you are climbing grades at a speed of 9-13mph and using cut-off 25%, The cylinder settings have been set to produce correct Tractive Effort at 65% boiler pressure (112PSI), trainz is over powered between 30PSI to 110 PSI Cylinder Pressure, however when you pass 112PSI the tractive effort drops and doesn't quite match the prototype for 80% boiler pressure (140PSI), so it is okay to run between 125PSI to 140PSI boiler pressure.
