Introduction

Open Rails is an open source train simulator that is currently being developed, and new features are continually being added to it. Open Rails have set as one of its aims that train performance should mirror real life operation as closely as possible. Thus a way of comparing the train's performance in the simulator, and in real life is critical to achieve this outcome. In addition, when a problem is identified, it is important to be able identify the problem, or if necessary communicate it in a way that makes it easy for different people to compare outcomes and provide suggested remedies.

The guidelines and methodology in the following pages describe a common and consistent test environment that allows all users to test locomotives and rolling stock against real life scenarios. They allow the testing of the locomotive, under 'controlled' conditions, which eliminates as many unknowns as possible.

This site guide covers the type of information that is available on this site, should be considered by the tester. It is suggested that the background information is read throughly first, and then the tester can review each of the relevant sections of the ENG/WAG file as appropriate.

OR Operation

Some simple converters are located on this page to assist in moving between imperial and metric units of measure.

Note: Information currently provided is, to the best of my knowledge correct at the time of writing. Full responsibility is on the user for any problems created by using this information.

Physics Setting Philosophy - only key configuration parameters will be changed between individual units, this may not achieve a true realistic response, but will allow comparitive response between different units.

Text Legend

Text used in wag and eng files will be colour coded as below:
Green - text that stays the same and does not need to be altered.
Red - text that needs to be altered to suit stock unit.
Blue - text that provides explanations about code.
