Irish Rail safely secured with Nord-Lock washers

Safety is everything for the Irish Rail. When they noticed that the bolts on their axle boxes were loosening due to vibration, they decided to replace the locking-wire mechanism on the wheel sets with Nord-Lock washers.

“Since the introduction of the Nord-Lock washers we have not had one instance of a bolt coming loose which give us a lot of comfort from a safety point of view”, says Conor Doyle, Senior Fleet Technical Support at Irish Rail.

Two years on since the first installation of Nord-Lock washers and Irish Rail has been more than satisfied with the outcome.
