Test Stock and Activities

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'.

BR "B1" Class Locomotive

The LNER B1 was the LNER's equivalent to the highly successful GWR Hall Class and the LMS Stanier Black Five, two-cylinder mixed traffic 4-6-0s. However, it had the additional requirement of having to be cheap because, due to wartime and post-war economies, the LNER, never the richest railway company, had to make savings.

With the change in the policies of British Railways, the B1s were withdrawn long before their projected economic working life. Excepting No. 61057, which was destroyed in an accident in 1950, the first normal withdrawal was No. 61085 in November 1961. The remaining locomotives were withdrawn between 1962 and 1967.

The B1 was classified as BR Class 5MT. Tractive Effort at 85% Boiler Pressure - 26,878 lbf.

In 1951 BR undertook "Performance and Efficiency Tests" on the B1 locomotive. These tests included a series of stationary plant tests at the BR Swindon Locomotive Testing Plant, and a number of controlled road tests on the Appelby to Dent section of Settle and Carlisle line of the BR. The test locomotive available on this page has been configured based upon the information provided in the BR test report titled 'Performance and Efficiency Tests with Exhaust Steam Injector - Eastern and Northern Regions - "B1" Class 2 Cyl 4-6-0 Mixed Traffic Locomotive - 1951'. This report describes a number of tests undertaken on the B1 class locomotive.

The test locomotive has been configured with the following OR features:

Physics by Mick Clarke

Extras for this locomotive if desired - B1 Class Cabview and Locomotive Sounds.

Two test configurations have been built for this locomotive to demonstrate the alternate means of configuring the locomotive. BASIC features contains information about the locomotive that is readily obtainable from INTERNET sources. ADVANCED features have been included in the ENG file to replicate the known parameters of the locomotive in the real world as far as is possible, based upon information available from the test report. In particular the Boiler Evaporation rate was reduced to the reported 25,000lb/hr steam rate and the burn rate from the report was added.The ADVANCED version produces results close to the reported values from the report. The loco achieves 70.4mph with a trailing load of 342 tons (uk). This is exactly in line with the prediction from the balance point on the calculated graph of Drawbar TE at 25,000lb/hr steam rate against Trailing Load Resistance.

BR "V2" Class Locomotive

The V2 2-6-2 locomotive was designed by Sir Nigel Gresley in 1935, the LNER V2 went on to become a highly successful design, working both freight and passenger services throughout the region until withdrawal in 1960. 184 in total were built, the first, Green Arrow, was presented to the National Railway Museum and has, until recently, run on the main line. Coming nearly ten years after the first A3s, the V2s had the same three cylinders and conjugated valve gear layout of the Pacifics and similar lines.

The V2's swansong came on the Edinburgh - Aberdeen run, working alongside the last LNER A2s and A4s. The entire class was withdrawn from service between 1962 and 1966.

The V2 was classified as BR Class 6MT and later as 7P6F. Tractive Effort at 85% Boiler Pressure - 33730 lb.

In 1953 BR undertook "Performance and Efficiency Tests" on the V2 locomotive. These tests included a series of stationary plant tests at the BR Swindon Locomotive Testing Plant, and a number of controlled road tests on the Reading to Filton section of line in the Western Region of the BR. The test locomotive available on this page has been configured based upon the information provided in the BR test report titled 'Performance and Efficiency Tests with Exhaust Steam Injector - Eastern and Northern Regions - "V2" Class 3 Cyl 2-6-2 Mixed Traffic Locomotive - 1953'.

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.
