RFI approves WEGH under-sleeper pads
ITALY: Infrastructure manager RFI has approved the use of WEGH Group’s concrete sleepers with under-sleeper pads on the national network.
The USP has two surfaces, one attached to the underside of the sleeper using a machine built by WEGH’s Olmi division to ensure consistency, and a resilient portion which is in contact with the ballast. This improves the distribution of the load, reducing ballast degradation and extending the interval between tamping and ballast replacement.
The testing required for the approvals process was carried out in collaboration with certification body RINA.
