136RE R10 (TR68) Rail — AREMA
Product Overview
136RE R10 (TR68) Rail is the R10 profile variant of the AREMA 136 lb/yd heavy-rail family, engineered for ultra-heavy haul, ports, mining and industrial crane applications. Supplied with profile drawings and full MTC; turnkey options (cut-to-length, drilling, heat treatment/head hardening and third-party inspection) minimize procurement risk and speed installation.

Engineering & compatibility notes
Do not assume interchangeability. R10 indicates a specific head/local profile variant within the 136RE family — local head radii, head-center width and straight segments differ and affect wheel–rail contact and turnout/frog fit. Always run a CAD overlay of the supplier DXF against your existing profile before acceptance.
Jointing & transitions: use matched joint bars or approved transition rails. Confirm bolt/hole patterns and clip/seat interfaces from the supplied drilling drawing.
Welding / thermit work: declare any HT/head-hardened rails in the RFQ — welding procedures, pre/post-heat and post-weld testing depend on rail heat-treatment.
Maintenance & grinding: head curvature differences may require adapted grinding programs and tooling — factor into lifecycle cost estimates.
