VTM-compact: The mini powerpack for hot-spots

Tremendous removal rate

  • Up to 2 mm per machining pass
  • Improved cutting process & more precision when removing material thanks to up-cut milling method
  • Rails are laser-scanned for pinpoint accuracy when lowering the tool onto the rail
  • Milling zone:+5° and -70° depending on the milling tool

Universally applicable

  • Ideal for short track sections, light rail or industrial rail facilities
  • Perfect for smaller areas requiring intensive machining such as level crossings, tight curves and start/stop areas
  • Suitable for the most diverse range of track construction types and all the common loading gauges thanks to its compact design
  • Variably adjustable to all the common track gauges and rail cants
  • Does not interfere with level crossings, and no dismantling of track signaling and switching equipment is required

100% free of dust and sparks

  • Currently not equipped with a downstream grinding unit
  • Reaons for “milling only”:
    • Rails machined completely spark-free in high-fire risk areas (e.g. In the petrochemical or wood-processing industries as well as tunnels and bridges, or during extremely dry periods)
    • Improved traction when starting form a standstill and braking

Simple logistics

  • Dimensions of a 20-foot container (TEU)
  • Numerous transport and loading options:
    Either by truck to the work site or by rail using any kind of traction vehicle
  • Easy on-railing at the site using a crane or a ramp
  • Height-adjustable coupling

Corrective applications

Road-rail milling truck: The universal genius

  • Transport truck and machine in one
    • Simple logistics & ideal for small-scale works and tram networks
    • Transfer via road or rail
    • Maximum mobility and flexibility
  • Simple on-railing & off-railing – right at the work site where possible
  • Short tooling times
  • Entire profile machined in just a single pass
  • Finish grinding thanks to integrated grinding equipment
  • Minimal dust and sparks produced
  • Dismantling of trackside switching and signaling equipment is not required

Track gauge correction

Milling grooved rails to reduce noise

  • Significant reduction in noise emissions through the removal of corrugations
  • Grooved rails fully reprofiled for the first time thanks to new milling wheel – and without removing the gap sealant
  • Removes larger amounts of metal including from the bottom of the groove towards the gauge corner
  • Milling of grooved rails with hardened rail heads and gap sealant

Side gouging in curves

  • The damage to rails that have always been replaced because of deep gouging can now be milled out.
  • A specially developed millling wheel relocates the critical zone approx. 4 mm below the side gouging.
  • Applications: side gouging in curves
  • The lower rails of curves can sometimes have severe burring, which is also removed

Switch machining (Vignole rails)

  • Complete reprofiling of the mainline and the turnout including frog, wing rails and points down to 20 mm
  • Minimal time required for machining
  • Reprofiling returns the switch to near-new condition
  • All switches with spring-action frogs can be machined
  • Not recommended for economic reasons: single-slip switches, double-slip switches and crossings

Thanks to a specially constructed tool and some adjustment of the software for the machining process, its possible to mill more than 95% of a switch including its wing rails, the frog and the points. Grinding with the Flexis System, specifically designed for the maintenance of switches, is then only required for the alignment work in the transition zones.

Milling level crossings

  • The tool on the SF02 road-rail milling truck has the same dimensions as a rail wheel, which allows it to machine rails all the way through a level crossing.
  • Clearance at the gauge corner complies with the European standard for wheel flanges: 38 mm laterally and a width of 42 mm
  • Ideally, the adjacent material should be 2 mm lower than the top of the rail.
  • The rail that has been damaged by the grit put down in winter is completely reprofiled.

Track gauge correction

  • Avoids having to close tracks to traffic
  • Prevents premature wear of the vehicles’ rail tyres
  • Reduces noise emissions and improves operational safety
  • Applicable wherever burring or flexural fatigue in the sleepers can cause gauge narrowing
