BR18

BR18 is a type of British railway brake shoe, commonly used on steam locomotives and diesel locomotives. The designation "BR18" refers to the British Railways standard for brake shoes, which were manufactured and supplied by the British Railways Engineering Division. These brake shoes are characterized by their rectangular shape and the use of a friction material, typically cast iron, to provide braking force. The BR18 brake shoe is designed to be easily replaceable and to fit a variety of brake shoe holders found on British locomotives. It is a critical component in the braking system of a locomotive, ensuring safe and efficient operation. The BR18 brake shoe has been in use since the early 20th century and remains a standard component in the maintenance and operation of British railway locomotives.
