Pandrol is a British company, which manufactures clips used on rail tracks.
[edit] Overview
The Pandrol clip was patented in 1957 by a Norwegian railways engineer, Per Pande Rolfsen. Nowadays it is common worldwide. Pandrol has manufacturing plants in 12 countries and 82 markets. Over 240 railway systems in 91 countries adopted its products. The original clip is now called the "PR-clip". The clip has to be manufactured with the right amount of tempering (or springiness) so that it exerts the right amount of force on the rail foot to hold it in place, but not so much force that the clip cannot be inserted or withdrawn.[citation needed]
[edit] Fastclip
The Pandrol "Fastclip" was introduced in 2000 to overcome some of the limitations of the original E-clip. In particular, the Fastclip is captive to the concrete sleeper to which it is attached and is more suitable for automatic insertion and extraction.[1]
