Introduction

Special locomotive types such as Rack locomotive are able to be configured within OR. This page describes some typical setups for them.

Rack Railway Locomotives

For a detailed description of Rack Railways and their operation see Rack Railways.

In broad terms, Rack locomotives will need to be configured with an appropriate combination of Steam Engines and Axle types.

The standard defining parameters are:

AxleRailTractionType ( x ), where x = Rack, Rack_Adhesion or Adhesion, should be added to the Axles code section.

AuxiliarySteamEngineType ( x ), where x = Adhesion, Rack or Booster, should be added to the Steam Engines code section.

ORTSRackShape () added to all relevant track pieces in the TSECTION.DAT.

ORTSRackRailGearFactor ( x ), where x = the ratio of the Cog Wheel radius to the Adhesion wheel radius. It is included in the Engine section of the ENG file.

BrakingCogWheelFitted ( true ) to be included in the Wagon section of either the ENG or WAG file.

As suggested in this information there are potentially three different types steam rack locomotives, as follows:

Riggenbach Braked Locomotives

For a detailed description of Rack Railways and their operation see Counter Pressure Brakes.

Currently only the Riggenbach brake system is modelled in OR, and in broad terms, the locomotives will need to be configured either with one or multiple Steam Engines.

For single engine steam locomotives ORTSCounterPressureBraking will need to be set to true, and added to the engine section of the ENG file.

For multiple engine steam locomotives CounterPressureBraking will need to be set to true, and needs to be added to the relevant Steam Engines section of the code within the ENG file.

Visual steam effects for the exhaust steam out of the brakes can be added as described on the Visual Effects page.

Similarly sound effects can be added by using the relevant sound triggers shown on Sound Event Parameters page.

A sample configuration of a Riggenbach locomotive can be found here.
