Handbook For Railway Steam Locomotive Enginemen

The burgeoning of the railway preservation movement all across the United Kingdom in the last 50 years has meant that there are now a considerable amount of steam locomotives preserved, maintained and in full working order and being run in frequent public service by preservation societies on heritage lines. This means that there is a continuing need for a practical handbook to help drivers and those responsible for maintaining the locomotives in safe condition for public use, covering all the basics of steam locomotive construction, technology and operation - this book fulfils that need admirably.The book is a reprint of an official handbook issued for the education of and day-to-day use by British Railways enginemen in late 1957, when it was distributed to all members of the BR footplate grades concerned with steam power. In lucid terms, and with the aid of over 90 contemporary diagrams, many of which employ a variety of colours to distinguish, for example, saturated steam, superheated steam, exhaust steam, air, oil and water passages, the book provides an accessible guide to the basic principles of steam locomotive construction and operation.

Handbook for Railway Steam Locomotive Enginemen

Priming (foaming in North America) is a condition in the boiler of a steam locomotive in which water is carried over into the steam delivery. It may be caused by impurities in the water, which foams up as it boils, or simply too high a water level. It is harmful to the valves and pistons, as lubrication is washed away, and can be dangerous as any water collecting in the cylinders is not compressible and if trapped may fracture the cylinder head or piston.

The most frequent cause is running the locomotive with too high a level of water in the boiler and is most apparent when the regulator is opened sharply or steam demand is high. Thus, sensible locomotive management by the operators will help to prevent the occurrence. The phenomenon is particularly evident in areas of impure water, where boiled water creates a foam, or a mist of droplets, filling the space that collects steam at the top of the boiler, to be drawn down the steam collector pipe in the form of slugs of water. If boiler water is condensed and re-used, any oil or grease must be extracted as this form of contamination is particularly likely to give trouble. 041b061a72
