Indian Railways is fastening the Rails on Concrete Sleepers over its entire network with the so-called MARK III Elastic Rail Clip (ERC), which had been evolved with a modified spatial bend by RDSO from the left-handed Pandrol 401 Series with an anti-clockwise bend of the rod.
The MARK III ERC is far away from being “fit-and-forget”. Each and everywhere on the IR network one can detect loose or fallen off ERCs. Regular controlling by a patrolling key-man is needed to push back loose or fallen off Elastic Rail Clips into the tunnel of the shoulder plate/housing.
To increase the Speed of Passenger-Trains to 160 kmph on existing Routes is a long-term corporate objective in India based on policy initiative. The risk of patrolling key-men on duty increases over-linear with the train-speed. Rails on tracks envisaged for 160 kmph “Semi High-Speed” routes demand a “fit-and-forget” attendance-free Fastening System without the regular need of a patrolling key-man pushing back loose or fallen off Elastic Rail Clips (ERC).
Worldwide the Pandrol Fast-Clips are increasingly superseding the right-handed Pandrol Brand e-Clips resp. left-handed 400 Series Clips. This Fast-Clip takes a trumped around the globe especially in England, Germany, France, Poland, Sweden, Estonia, Georgia, Lithuania, Russia, Serbia, Hungary, Corsica, Sri Lanka, Cambodia, Malaysia, Saudis, Australia, China and USA.
With Fast-Clips no patrolling key-man will be needed. This ERC is an advisable solution when it comes to a track renewal or upgrade for envisaged “Semi High-Speed” routes.
