What rail fasteners does IR use?
IR uses various kinds of Pandrol design fasteners, ERC Mark III (850-1100kg toe load), and ERC Mark V (1200-1500kg toe load) (the latter developed by RDSO). Pandrol ‘J’ clips, often yellow in colour, which have a lower profile and lower toe load), are used where they need to be removed and reinserted easily and where ordinary clips might interfere with the fastening of fishplate bolts.
