Introduction

This webpage explains how all parameters that are used to configure Rolling Stock in the Open Rails Trail Simulator are to be recorded in ENG and WAG files. For each parameter, the name, description, possible values, unit of measure and if useful an example is provided. It is also indicated if the parameter is a BASIC requirement to “make the stock roll” or an ADVANCED parameter that is used for locomotive tuning or to closely mirror real world physics. The ENG file parameters are presented per locomotive type (Steam, Diesel and Electric), as each locomotive type has a unique set of parameters in addition to parameters that are common across all locomotive types.

We would appreciate your feedback, so if you have any comments or suggestions regarding the content on this page, please use the contact form.

What are ENG and WAG Files

ENG and WAG files contain the parameters that define the physical characteristics and behaviour of each type of rolling stock that is used in the Open Rails simulator. Parameters for Steam, Diesel and Electric locomotives are captured in ENG files. Parameters that define non-powered rolling stock like passenger carriages and freight cars are recorded in WAG files.

Filename and Location

ENG files name and folder: ../Route/Trains/Trainset/locomotive-name/locomotive-name.eng
WAG files name and folder: ../Route/Trains/Trainset/wagon-name/wagon-name.wag

Index

Using Include files

An Open Rails INCLUDE (INC) file uses an "include" statement to insert the content of another (original) file. INCLUDE files can be used to streamline the ENG or WAG files as follows:

Separation of MSTS and OR parameters - the original ENG or WAG files are maintained in a form suitable for operation in MSTS. The file that contains the parameters required specifically for OR operation will include the original ENG or WAG file, which avoids the duplication of the original ENG or WAG file code.
Duplication of common elements - allows common elements used on multiple occassions by different rolling stock to be managed from a single source file. For example, brakes or couplers could be specified in a single source file, and then inserted (included) into multiple ENG or WAG files.

INCLUDE files can be used to add information to either rolling stock or routes.

To implement an INCLUDE file it is necessary to follow the following steps:

Create a folder called OpenRails that you wish to insert the INCLUDE file to, in one of the following locations:
- within the root folder of the route (eg. ../Routes/"my route"/OpenRails),
- in the folder of the rolling stock (eg. ../Trains/Trainset/"my train"/OpenRails), or
- anywhere in the OR file structure, but in this instance the full path name to the folder would be required to refer to the original file.
The INCLUDE filename must be the same as the "original" filename, for example, the statement:

      include ( filename ).

entered at the start of the Open Rails specific INCLUDE file:

      C://Open Rails - CTN Test Route/Trains/Trainset/AU_NSW_1905_Goods_Wagons/OpenRails/~CTN-PT5-Tender-FC.wag

will include "original" file:

      C://Open Rails - CTN Test Route/Trains/Trainset/AU_NSW_1905_Goods_Wagons/~CTN-PT5-Tender-FC.wag

Index

File Structure of ENG and WAG files

It is hightly recommended to organize the parameters in the ENG or WAG in the sections as shown on this page and the example files. This makes reading and checking the files easier and the structure acts as a checklist to ensure that parameters are not omitted or duplicated in different parts of the file.

Each section contains the following information:

A Comment statement with:
- Section Name: the topic to which the parameters in this section are reated, for instance "General Information", "Couples", "Brakes", "Lights", etc.
- Included in section: description of the type of information found in this section.
Code - the parameters that may appear in this section. The examples below show the syntax of parameters and ad the preferred formating.
Link - if available, a link is provided to the appropriate CTN Physics page with related detailed information on the topic in the section.

When building the ENG or WAG files, it is highly recommended to add Comment statements to the code, with an explanation and information for future reference.

ENG and WAG files can be configured from "BASIC" to "ADVANCED":

BASIC - Rolling stock can be customized using data and information that is readily available from the Internet. Open Rails uses default values for a number of parameters, that therefore can be excluded from the ENG and WAG files. Typically only the information that is relatively unique to the rolling stock is modelled. This configuration type is best suited for users who are more interested in the visual effects of OR without worrying about detailed physics, or where accurate physics information is not easily obtained.
ADVANCED -In Open Rails, rolling stock can be customized closely matching real life performance. Finding the ADVANCED parameter data often requires more in-dept research into information such as test reports, etc. This configuration type is best suited for users who want as accurate representation of train performance as possible.

Engine ENG File Structure

The ENG file has both a Wagon and an Engine section, as shown below. The engine file for a steam locomotive will have different sections when compared to a diesel or electric locomotive.

Examples of ENG and WAG files

A number of sample locomotives can be downloaded on the Test Stock and Activities page. Please note that not all the locomotives are up to date including the latest features. If you are searching for a particular feature as an example, you may need to look at a number of the models on this page to find a recent example.

Once the files have been built, make sure that they are tested using some of these performance tests
