PD CEN/TS 15427‑2‑2 is the second sub-part of the second part of the PD CEN/TS 15427 series of documents. PD CEN/TS 15427‑2‑2 specifies the requirements of materials intended to be applied to the interface between the wheel tread and the rail crown (active interface). PD CEN/TS 15427‑2‑2 can be applied either directly or indirectly to the wheel tread or rail.
PD CEN/TS 15427‑2‑2 outlines the information required for most approval procedures, the method of testing, and routine control/monitoring of the material.
NOTE: PD CEN/TS 15427‑2‑2 does not deal with adhesion materials, for example:
PD CEN/TS 15427‑2-2 on railway wheel tread is useful for:
Wheel/rail friction management is the systematic assessment and implementation of friction control, combined with the technology to monitor, maintain and manage friction to achieve short and long-term performance benefits.
PD CEN/TS 15427‑2‑2 provides the requirements for the top of rail materials and testing and routine control/monitoring of the material.
PD CEN/TS 15427‑2‑2 provides information about rail lubrication systems (train-borne or trackside) that delivers lubricant to the active interface.
The manufacturing process and routine tests of top of rail materials are also provided in PD CEN/TS 15427‑2‑2.
Overall, PD CEN/TS 15427‑2‑2 provides characteristics of grease type material, liquid type material, and solid type material to maintain rail wheel performance and ensure reliable braking performance.
