Test Stock

Aim - to provide suitably configured test rolling stock for Open Rails, and also provide some templates that may assist Open Rails model developers.

The primary purpose of these locomotive is to demonstrate the Open Rails steam functionality, and therefore some of the locomotives may not be visually correct. For example the Climax is a narrow guage version, but will perform satisfactorily. Additionally some of the locomotives do not have the cabviews or sounds included, so these may need to be downloaded and installed separately. The absence of cabviews or sounds will not impact the physical operation of the locomotive.

Introduction

If you don't have Open Rails installed, or are not familiar with it, try reviewing this page first OR Installation.

This stock can be run on the test route to perform Steam Model performance testing. By default rolling stock and activities from this page will be installed in the folder C:\Open Rails - CTN Test Route. You may wish to change the folder if you wish, or have installed the test route in a different location.

Example ENG and WAG files are provide on the examples page.

It is recommended that you read the following pages to provide relevant background and context to the operation of steam locomotives - Introduction to Steam Train Physics and OR Steam Locomotive model. For those interested in advanced physics configurations refer to Open Rails Steam Parameters for Advanced Modellers.

The locomotives on this page usually have two configuration levels provided in the installation pack:

Where possible these models have all the known functions and features available for steam locomotives, and which can be configured in OR, that were known to be fitted to the locomotive.

When configuring the physics of a locomotive the various functions and features of OR can be tested with the different tests described on the Open Rails Function Testing and the Steam Locomotive Performance Testing pages.

Test locomotives - Type = Simple, Superheated

These locomotives are classified as superheated steam, simple type of steam locomotives.

Superheated locomotives used steam that was heated well above the normal (saturated) temperatutre of steam. Typically this could be as much as an additional 250-300 degrees Fahrenheit. The main benefit of this increased temperature was that the steam was more "efficient" when it was injected into the cylinder. Because of the extra heat in superheated steam condensation in the cylinder was less likely to occur, this resulted in a reduced steam consumption and consequently reduced coal consumption. Despite the fact that the other performance parameters were very similar to the saturated locomotive, the steam and coal reduction significantly improved the efficiency of the steam locomotive.

BR "Merchant Navy" - #35009

The following test locomotive is configured with the same parameters as described in the BR test report titled 'Performance and Efficiency Tests - Southern Region Modified Merchant Navy Class 3 Cyl 4-6-2 Express Passenger Steam Locomotive 35020'.

Geared Locomotives

Geared steam locomotives were developed for use on light industrial type railways that might typically have sharp curves or steep grades. For a fuller description see here.

The mjaority of geared steam locomotives had fixed gearing, and these included all the Shay classes and the Climax classes except for the A class which had two gears that could be changed whislt in operation. Open Rails has been set up to allow for both the Fixed and Selectable gear type steam locomotive.

The gearing on these locomotive typically increased their tractive effort by a factor of 2-3 times.

Compound Locomotives - Type = Compound, Saturated

Compound locomotives were developed to increase the efficiency of steam usage. A wide variety of compound locomotives were develped in the 1800s, but became less popular in the early 1900s. They were generally found to be more difficult to maintain, and they were generally replaced by superheated locomotives. The current OR model is based upon a Woolfe type engine without a receiver between the HP and LP steam cylinders.

Rainhill Test - small locomotive

In the late 1820s, a new railway was being built between Liverpool and Manchester in the UK. The directors of the railway line were uncertain as to whether to use stationary steam engines spaced at equal distances along the line or a steam lcomotive. They decided to hold a competition with a £500 prize to decide. The competion was held on a flat section of the railway at Rainhill, thus the Rainhill Trials took place, and frimly established the place of the locomotive on the railways.

Competition rules were established, and one of the key requirements were for the boiler pressure not to exceed 50 psi.

Five locomotives were entered into the competition, and after the trial was complete, George Stephenson's Rocket locomotive was announced as the winner. The Rocket, with a boiler pressure of 50 psi, and cylinders of 8 in x 17 in was extremely small by modern standards, and only produced a maximum tractive effort in the order of 820 lbf.

Thus the Rocket with its low tractive effort it is a good test for the OR Steam Model and has also been used to check the OR performance. It can be downloaded from the link below and trialled.
