Foreword These pages contain notes and observations on the safe operation of Road Steam Engines (RSE), in particular traction engines, steam rollers and their various variants. There is quite often a significant difference between the operational characteristics of the various makes of RSE and even the various types within a specific make or type. These notes therefore should be seen as a guide only and not be construed as an operations manual for any specific engine. The general principles, however, apply to all RSE. The information herein has been drawn from numerous sources including, inter alia, personal experience and observation, interviews, non copy write historical notes, modern technical accounts etc. The work is divided in to a main body and eight information appendices and one appendix dealing with the assessment of competency. WARNING!! RSEs are potentially dangerous pieces of machinery, there are hot metal parts, scalding water and steam, and unguarded moving parts, extreme caution is needed at all times. BASIC OPERATING PROCEDURE FOR ROAD STEAM ENGINES Page 4 BASIC OPERATING PROCEDURE FOR ROAD STEAM ENGINES 2. Crew Most RSE will have a crew of two at any given time, nominally the driver and steersman. • This may vary given circumstances, e.g. when on static display • Note that the “driver” is the person controlling the engine, not steering it 3. Notes on Boiler Type RSE the subject of these notes, generally employ a “Locomotive Boiler”. That is a boiler which: • Is designed to be movable • has a single pass of gas from firebox to chimney • Uses many small tubes to allow the gas flow from firebox to smokebox • Has exhaust steam from the engine directed up the chimney to create a draft for the fire As far as boilers go, it is highly efficient and one of the only designs that automatically increases steam generation proportional with steam use due to the engine exhaust being used to create draught for the fire. The harder the engine works, the greater the draft, and providing the fire is in good order and well managed, the greater the steam production. • Key o A = Tubes o B = Fire box tube plate o C = Front tube plate o D = Stay bar o E = Fire box stay o F = Fire bar o G = Fire box girder stay o H = Girder stay bolt o I = Fire hole door o J = Throat plate o K = Front Plate (back head) o L = Outer fire box (wagon top) o M = Mud door (wash out door, hand hole door) o N= Smokebox door o O = Damper o P= Foundation ring (“Z” ring in

  • Guide to Off-Road Vehicle & Equipment Regulations
    Guide to Off-Road Vehicle & Equipment Regulations The California Air Resources Board (CARB) is actively enforcing off-road diesel and large spark-ignition engine vehicle and equipment regulations in support of California’s clean air goals. Enforcement of clean off-road vehicle rules provides a level playing field for those who have already done their part and are in compliance. If your fleet does not meet state clean air laws, you could be subject to fines. This booklet provides basic information and resources to help take the guesswork out of California’s clean off-road vehicle and equipment requirements. This booklet is not comprehensive of all CARB regulations that an off-road fleet may be subject to, but provides basic information specific to the following: • Regulation for In-Use Off-Road Diesel-Fueled Fleets • Large Spark-Ignition Engine Fleet Requirements Regulation • Portable Equipment Registration Program DISCLAIMER While this booklet is intended to assist vehicle owners with their compliance efforts, it is the sole responsibility of fleets to ensure compliance with applicable regulations. For more information or assistance with compliance options, visit arb.ca.gov/offroadzone, call the toll-free hotline at (877) 59DOORS (877-593-6677), or email at [email protected].

  • Steam Engine Collection
    STEAM ENGINE COLLECTION The New England Museum of Wireless And Steam Frenchtown Road ~ East Greenwich, R.I. International Mechanical Engineering Heritage Collection Designated September 12, 1992 The American Society of Mechanical Engineers INTRODUCTION It has been said that an operating steam engine is ‘visual music’. The New England Museum of Wireless and Steam provides the steam engine enthusiast, the mechanical engineer and the public at large with an opportunity to experience the ‘music’ when the engines are in steam. At the same time they can appreciate the engineering skills of those who designed the engines. The New England Museum of Wireless and Steam is unusual among museums in its focus on one aspect of mechanical engineering history, namely, the history of the steam engine. It is especially rich in engines manufactured in Rhode Island, a state which has had an influence on the history of the steam engine in the United States out of all proportion to its size and population. Many of the great names in the design and manufacture of steam engines received their training in Rhode Island, most particularly in the shops of the Corliss Steam Engine Co. in Providence. George H. Corliss, an important contributor to steam engine technology, founded his company in Providence in 1846. Engines that used his patent valve gear were built in large numbers by the Corliss company, and by others, both in the United States and abroad, either under license or in various modified forms once the Corliss patent expired in 1870. The New England Museum of Wireless and Steam is particularly fortunate in preserving an example of a Corliss engine built by the Corliss Steam Engine Company.

Introduction ”Stafford” is a large, robustly-engineered locomotive which, whilst not intended as a scale model, is based on typical industrial engine practice of the early twentieth century. Our aim has been to produce a powerful engine which is reliable and easy to maintain. The engine weighs 430 pounds and requires careful handling to avoid injury – mechanical handling, using a hydraulic lifting bench and ramps etc is highly recommended, the engine cannot easily be handled or lifted manually. Terms used in this manual Throughout this manual, right hand means the right hand side of the engine from the driver's point of view – so, for example, the reversing lever is on the right hand side, the brake handle on the left. 2. The new engine Your new engine will be delivered assembled, tested and ready to run. It will have been run on compressed air in our workshop to check valve setting then steamed prior to despatch to check operation of injectors and the safety valve. 3. Controls The engine controls are as follows: Regulator on right of fountain, opens counter-clockwise, closes clockwise Injector steam valves

  • Instruction Manual - D&RGW K-27 Live Steam
    Instruction Manual - D&RGW K-27 Live Steam ACCUCRAFT TRAINS 33268 Central Avenue Union City, CA 94587 Tel: (510) 324-3399 Fax: (510) 324-3366 [email protected] D&RGW K-27 2-8-2 #463 Instruction Manual - D&RGW K-27 Live Steam Introduction This locomotive is a model of a K-27, one of fifteen ordered by the Denver & Rio Grande Western Railroad in 1902 and delivered in 1903. The Rio Grande numbered them Nº 450 through Nº 464. The “K” designation was the Rio Grandeʼs code for a Mikado, or 2-8-2. The “27” referred to the locomotiveʼs tractive effort, in this case 27,000 pounds. Only two K-27s remain today, one in Michigan, running on the Huckleberry Railroad, and one running on the famous Cumbres & Toltec line in Northern New Mexico/Southern Colorado. Operating a model live-steam locomotive is much different from running an electrically powered engine. It is a more hands-on, interactive experience. The locomotive must be periodically fueled, oiled, and watered. As supplied, the K-27 is manually controlled, which means that you must actually drive the locomotive using the controls in the cab, just as you would a full-size engine. The performance of the engine is also unlike electric locomotives. The K-27 should pull a dozen or more standard-size freight cars on good, level track. Grades and sharp curves will diminish its capability. A good engineer will learn the engineʼs characteristics and idiosyncra- sies over time, to get the best performance and longest duration from it.
