Compatibility & Engineering Notes
Although part of the 115RE/TR57 family, R10 is a profile variant. Local parameters (head width, arc radii, straight segments) affect wheel-rail contact, clip fit and turnout/frog compatibility. Perform CAD overlay checks and confirm hole/clip dimensions before substitution.
Engineering recommendations
Submit existing profile → we perform overlay comparison and compatibility report.
Use the same profile for precision components (turnouts, frogs).
Use milling or short welded transition if required to ensure smooth transition.
FAQs
Q: What is 115RE R10?
A: 115RE R10 is an R10-profile variant of the AREMA/TR57 (115 lb/yd) heavy-rail section.
Q: Can you provide HT/hardening?
A: Yes — Available on request; quote includes process and inspection requirements.
Q:What differs between 115RE and 115RE R10?
A: Both belong to TR57 family; the difference is in head/local profile details (head-center width, arc radii, straight segment lengths), producing small differences in contact geometry and mass distribution (hence 56.80 vs 56.90 kg/m reported).
Product Highlights
