Manganese Crossing EHZ CENTRO MN13

The managanese crossing "EHZ CENTRO MN13" is a common monoblock crossing.

The complete central part of the crossing is cast in one block from high-manganese steel. This part corresponds to a monoblock crossing, with the only exception of the length of the fishing table. Closure rails are flash-butt welded to the four ends of the central block using a special flash-butt welding technique (intermediate piece welding). The bearing surfaces (seat of the plates) as well as the complete area of the running and head surfaces are milled and/or planed. The thus achieved manufacturing accuracy facilitates optimal wheel overrun and interchangeability of crossings on existing sets of plates.

Materials and quality inspection:

  • Rail in line with rails steel within turnout
  • Crossing: High-manganese steel (13% Mn) according to EN 15689
  • Visual and geometric check
  • Penetration test: Flash-butt weld
  • Radiography test: Prototypes
  • Mn13 casting according to EN 15689

Benefits:

  • Can be thermit welded into the track
  • Requires low maintenance (no bolting)
  • Excellent wear resistance through work-hardening process of the high-manganese steel during operation
  • Optimised wheel overrun
  • Guaranteed interchangeability
  • Can be used for curved turnouts
  • Repair and built-up welding possible without preheating
  • Suitable for all types of rail fastenings
  • Reduced maintenance expenditure, particular in case of high axle loads because of the possibility of pre-hardening the running surfaces
