In the subsequent decades, it focused on the development and manufacture of such fastenings for securing rails to railway sleepers, being awarded numerous patents for this work.

[8][9] During 2023, Pandrol launched a Common Interface System for ballastless track; it is designed to accept a variety of different screwed and non-screwed rail fastening assemblies so that they can be adapted quickly and affordably to suit different requirements and restrictions.

[13] In 1958, Sanson was approached by a young Norwegian engineer named Per Pande-Rolfsen, who had invented a new type of indirect fastening which was fully resilient and did not transmit vibrations from passing trains.

[14] The self-tensioning spring clip was far more adaptable than any other product on the market, and ERS registered international licensing rights on behalf of Rolfsen.

In 1992, Pandrol trialled an innovative new fastening, the Fastclip; it was quickly adopted by multiple heavy freight railways in North America.

[citation needed] During late 2003, Réseau Ferré de France (RFF) mandated the use of the Fastclip as its standard fastening for both new lines and renewal activities.

[16] In early 1999, the British engineering conglomerate Charter plc announced that it was seeking to spin out its Pandrol Rail Fastenings subsidiary.

[21] During the late 2010s, Pandrol Rahee Technologies was contracted to design, manufacture and supply a bespoke rail fastening system for the Mumbai Naval Dockyard.

[25] Following the sale of KLK Electro Materiales in 2021, the engineering, development and trading of rigid and tramway catenaries was carried out by Pandrol instead.

[26] During December 2020, Pandrol opened a new Centre of Excellence in Raismes, France as a part of the expansion and improvement of the company's training facilities.
