Most rail applied compound systems used an LP receiver between the HP and LP, and there were also various systems used to admit small amounts of HP steam to the LP cylinder/s while starting, usually switched off after a couple of turns on the driving wheels. The Woolfe system operates by direct admission from the HP cylinder/s to the LP cylinder/s. While the Woolfe system is a simple one to model, it was not used by most engineers who dallied with compounding. I have at last been able to devote some time to testing the steam compound model. That's fantastic to hear you guys have developed such an advanced steam model that this is possible!!!! Looking forward to seeing where this leads to, for sure! To demonstrate the operation of the compound locomotive, test model can be found here. This is simulated by pressing the "P" key which toggles the valve open and closed to alter the steam flow. To operate in simple mode a steam valve was used to change the steam flow to the cylinders so that it bypassed the HP cylinders and only used the LP cylinders. The LP cylinders use the new parameters below.Ī compound locomotive could typically be operated in compound mode, or simple mode. The HP Cylinder details are entered into the ENG file in the current cylinder parameters. It is highly recommended that the above parameters be included in all steam ENG files regardless of the type of steam locomotive with the appropriate values above to ensure the selection of the correct model.Ĭompound locomotives normally had a set of High Pressure cylinders and a set of Low Pressure cylinders. To allow this the following new ENG file parameters have been added:Īllowable values are: Simple, Compound, GearedĪllowable values are: Saturated, Superheated Given the number of different steam locomotive models now supported by Open Rails, it is now necessary to definitively define which steam model is required. It is modeled on a balanced 4 cylinder balanced Vulcain model similar to that manufactured by Baldwin. The OR steam model now is able to simulate a compound type steam locomotive.
