About This Site
Railway Technical Web Pages is a website designed to inform and educate about railway technology and operations around the world. This page gives some details about the site, how to use it and how it was constructed. We welcome feedback and suggestions for new subjects.
Although this site is written from the perspective of the UK based railway industry, most of the information is valid for railways internationally. Differences between UK practices and those in other countries are noted from time to time, if relevant. Much of the technology is the same, wherever it is used. What can differ from one system to another, is how the technology is used and how the industry is regulated.
Language and Measurements
British English is used on this site and metric measurements are the norm unless otherwise specified. On many pages, references are made to systems or technology used in different countries around the world. Imperial and US measurements are quoted where appropriate. A list of the more common variations between UK railway language and US railroad language is contained in US-UK Terminology.
This web site was first opened on 21 January 1998. It was developed from an Intranet site introduced for a company in South Africa in 1994 to provide a source of information to those interested in the technical aspects of the railway business. In January 1999, already too big for its original home, it moved to the Trainweb site. It is now based in its own domain at www.railway-technical.com.
The site covers modern systems and steam locomotives. There are some glossaries, with the contents arranged in alphabetical order, and many articles with diagrams and photos where appropriate. There are selected links to other technical pages. There is a word search facility to help you find the subjects which interest you. There are 60 separate pages covering a wide variety of subjects.
This site is the Internet version of the supermarket "no name" branding. It's plain and simple. It has no frills. It's here for those who are interested in railway technology as a hobby or professionally. Don't look for flashy graphics or frames. There aren't any. There are simple diagrams and some photos and more will be added as the pages develop.
There are regular updates, particularly when people contribute with additions, ideas, pictures, links and any useful suggestions. Contributions from professionals or transportation experts are welcomed. If you would like to comment or contribute, contact RTWP here.
