Taltal No. 61 Engine Spec

Taltal No. 61 Engine Spec

This engine spec is based on a maximum tractive effort of 27615 lbs and a max hp of 650@ 28 mph at rail head. Max speed is set at 20 mph for DCC operation - with CAB mode speeds above 40 mph are possible. The power curve used as a basis for setting this spec was developed with the tzSTEC program and should represent a realistic approximation of the locomotive's performance. The parameters used above are in some cases changed from actual values for use in Trainz to give a more prototypical performance within the limitations of the Trainz steam physics system. In particular piston area has been reduce based on piston-max-vol (cylinder vol) and boiler-to-piston-flow to obain a starting TE consistent with the prototype. Piston-min/max-volumes have been increased to obtain prototypical water consumption rates.

For use in TRS2004 the TE at starting is set to 120% of the prototype's rated performance - to compensate for the TRS2004's incorrect effect of gravity on grades - and reduces to 100% at 28+ mph. In TRS2006 the included steam-power curve will give 100% at starting.

No of axles has been increased form 6 to 53 to account for increased resistance of steam locomotives - approx 20lbs resistence/ton of weight on drivers.
