Rail Expansion Formula at Ryan Knight blog

Rail Expansion Formula. Railroads deal with thermal expansion by heating the rail prior to installation. Multiply the difference in starting and ending temperatures by a coefficient of thermal expansion that’s easy to look up in a table. Additionally, various technologies utilizing wayside devices are implemented to detect rail faults. And, engineers can predict the change in length from most materials with a pretty simple formula. Introduction the role of the rail connections (rail joints) is to ensure the continuity of rails without vertical and horizontal ‘step’, as well as directional break. If the temperature is increasing then the rail will. In this formula, α is the steel expansion coefficient = 11.5·10 −6 mm/mm°c. The maximum expansion gap gmax can be computed as: This method involves heating the rails using a special machine that blows hot air onto the rails. In laying track, provision must be made for expansion and contraction of the rails, due to changes of temperature. Therefore, the rail is heated to its rail neutral temperature, being heated, then cooled as the rail is laid.
