Magnetic bosses 525 are provided on an interface plate 517 which can be permanently or semi-permanently attached to the tensioner chain or track, and they are received in corresponding recesses 529 on a base plate 527 of the tensioner pad 511.The magnetic bosses 525 can comprise permanent or rare earth magnets 531, such as neodymium or samarium-cobalt magnets. The magnets 531 are used to attach the tensioner pad 511 to a track or train. The magnets 531 can be retained in the bosses with use of a resin and/or a cap which may be bolted to the boss 525 through the magnet 531.
