Predicting Locomotive Performance
PREDICTING LOCOMOTIVE PERFORMANCE . W. B. Hall. F R Eng., F.I.Mech.E. The more efficient locomotives tested towards the end of the ‘steam era’ had overall thermal efficiencies of around 7 or 8 percent when working at optimum conditions; that is, the work done at the drawbar was 7 or 8 percent of the calorific value of the coal burned. When account is taken of the energy losses from the boiler (mainly unburned fuel and heat carried away by the products of combustion) and of mechanical losses between the cylinders and the drawbar, the residual thermal efficiency referred to the cylinders could be as high as 14% or 15 %. By comparison, the efficiency of a perfect heat engine operating with similar steam conditions and exhausting to the atmosphere would be around 20%. The evolution of designs capable of the above performance had proceeded against a background of considerable mechanical ingenuity and engineering insight, but with an almost total lack of a theoretical framework for some of the more important processes involved. Mechanics and to some extent properties of materials were exceptions, but until the early part of the 20 th century the theoretical understanding of fluid mechanics, heat transfer and irreversible thermodynamics was not adequate to provide a theoretical framework for crucial aspects of design. Design ‘rules’ there were in abundance, but many were limited to only small variations from the test data from which they had been derived; most were purely empirical, and some were dimensionally unsound. The situation in the 1930s is well illustrated in a series of articles in the Railway Gazette by E.L.Diamond 1 which reviews both the nature of the problem and the many attempts to produce theoretical guidelines for design purposes. -

A Brief History of Front-End Research and Latest Developments
A Brief History of Front-End Research and Latest Developments Ir. J.J.G. Koopmans Ph.D. Paper presented during the conference on “Developments in modern Steam Traction” in the National Railway Museum in York, 11th of December 2006. 1 Introduction This paper will cover some of the historic highlights of the development of front-ends during the last 200 years. It is also intended to give a phenomenal description of the functioning of a front-end. Illustration and proof of the examples is provided by some of the results of the tests with the RTM 54 steam locomotive. Notion The discussion is about the use of exhausted steam to create artificial draught in the boiler of steam locomotives. Figure 1 Terence Cuneo's painting of the first steam locomotive The history of the front-end started with Richard Trevithick, who mounted a blast pipe from the cylinders to the chimney, and turned its orifice upwards. The 20th century painting by Terence Cuneo, present in the Welsh National Museum, shows this detail together with the feedwater heater around the blast pipe. The picture shows the joyous moment it represents, but this author has some reservations about the way Trevithick is represented, walking with a spanner in his hand. Locomotive owners and engineers have a common and lasting tendency to be on the locomotive themselves! Some 60- years later the first serious research on the subject was started by Prof. Zeuner1. He used a simplified model of a front-end. During the tests he found that certain dimensional ratios in the front-end gave an asymptotic limit to its performance. -

Born out of Tragedy and Riddles, his lineage traceable, unerasable, back through the great houses of Chapelon, Giffard, Stephenson, Belpaire and Watt, the Duke was laid to rust by the sea, a few meagre miles from the mills that shaped the steel that formed the frames that bore the machine that Crewe built. Time passed and the Duke was made well again by kindly strangers. -

Buses That We Don't Have Current Details For
Check List - buses that we don't have current details for The main lists on our website show the details of the many thousands of open top buses that currently exist throughout the world, and those that are listed as either scrapped or for scrap. However, there are a number of buses in our database that we don’t have current details for, that could still exist or have been scrapped. The buses listed on this page are those that we need to confirm the location and status of. These buses do not appear on any of our other lists, so if you're looking for a particular vehicle, it could be here. Please have a look at this page and if you can update any of it, even if only a small piece of information that helps to determine where a bus is now, then please contact us using the link button on the Front Page. The buses are divided into lists in Chassis manufacturer order. ? REG NO / LICENCE PLATE CHASSIS BODY STATUS/LAST KNOWN OWNER J2374 ? ?

We had a should be retained. The rest of the hanger fascinating tour of the site. We started at has items from the Museum of the library and archives, where we were Photography, and the BBC historical treated to a sample of the rare books and collection. Some of the other hangers, manuscripts. These included a collection which hold Science Museum items, are in of early Bradshaw guides and timetables, a poor condition, with holes in the side a collection of Bourne paintings, and cladding, although the roofs appear technical drawings. Other items displayed water-tight. Inside are aircraft, including for us were a copy of Charles Darwin's a De Havilland Rapide in Railway Air manuscript, and a portfolio of superb Services Livery, steam traction engines, hand-coloured prints of Egyptian bicycles, cars, buses, trams, missiles, and monuments commissioned by Napoleon the world's first hovercraft. The hangers during his Egyptian campaign. will need re-cladding or replacing in due We then moved on to visit four of the course, possibly with a view to providing storage hangers, including the one a (chargeable) storage service to other FOR CONTACTS IN FNRM SOUTH OF ENGLAND housing the reserves from the NRM. -
Press Information
12 February 2019 PRESS INFORMATION For immediate publication A BUMPER YEAR FOR HRA AWARDS Saturday February 9th saw the celebrations surrounding the Heritage Railway Association’s 2019 annual awards. At a gala dinner in the Burlington Hotel, Birmingham, attendees were entertained by guest speaker Pete Waterman, prior to an awards ceremony that recognised the very best of the UK’s heritage rail industry. The HRA Awards recognise a wide range of achievements and distinctions across the entire heritage railway industry, and the awards acknowledge individuals and institutions as well as railways, tramways and cliff railways. The February 9th event saw the presentation of awards in record 15 categories, which includes one completely new award. Several categories saw a record number of nominees, and in one case, joint winners. The Statfold Barn Railway won the Morton’s Media (Heritage Railways) Interpretation Award, for their outstanding museum of international narrow gauge railways, and repository of information and artefacts relating to the Hunslet engine. The Railway Magazine Annual Award for Services to Railway Preservation was won by John Bate of the Talyllyn Railway, quite possibly the world’s longest-serving heritage rail volunteer, and whose skills have made a unique contribution to railway preservation. The NER 1903 Electric Autocar Trust won double honours. The Trust took the Morton’s Media (Rail Express) Modern Traction Award, for their restoration of the pioneering 1903 NER Autocar, the first railway vehicle to combine an internal combustion engine with a generator and traction motors, and thus the forerunner of all modern trains. Underlining their achievement, the Trust also won the Heritage Railway Association Manisty Award, one of the heritage rail industry’s most prestigious awards, which acknowledges an outstanding contribution to railway preservation. -

Thank you. Now, next year’s diary (see back page). I’m sure everyone will agree – our Secretary Peter Holden has put together a terrific programme of talks for the year. On April 26th, we have Alan Whitaker and Jan Rapacz covering the second volume of the GN lines west of Bradford, and after the great article about Deltics and train songs by Spencer Vignes in the last Circular, Spencer is now booked to give us a show on November 22nd. Thanks to our two stalwart contributors Gary Hayhurst and Peter Holden for the main issues in this issue – if they didn’t manage to get out and about so much, and submit accounts of their adventures (and photos), there wouldn’t be much for you to read. Let’s give them a chance to rest – you other members, please send in your articles! By the way, I have spread out these two articles, so that their photos accompany them in the right place. 1 Statfold Barn Gary Hayhurst The National Railway Museum for narrow gauge? On the 4th June 2016 along with three other friends I paid a return visit to Statfold Barn. -
