These can be used by Track Engineers for a better understanding of the physics behind the rails’ behaviour when subjected to temperature variations and can also help understanding the specifications and requirements mandated in the current standards covering the management of jointed respectively CWR track. Multiple thermal force diagrams will be presented for both jointed track and CWR applications. This first article is presenting general principles and theoretical considerations on the rails affected by thermal variation.

This article presents a classic calculation model of the thermal forces for jointed track, used to define the joint gap variation due to rail temperature variations. It presents the calculation of the joint resistance (clamping) force and discusses the influence of different parameters on the way the forces and joint gap vary.

The Journal, Vol 135 Part 2, April 2017. Permanent Way Institution. It presents the calculation of the joint resistance force for British rail joints, based on the bolt tightening torque and on the rail joint dimensional parameters. It is extensively based on the calculation method presented by Prof Dr Eng Constantin Radu in the Railway Track Courses at the Technical University of Civil Engineering Bucharest (TUCEB).
