What is the AUTECH AT VM 8000?
The AT VM 8000 combines a Viktor Meili road-rail chassis with a multi-stone grinding system for corrective and preventive treatment on tight-radius urban rail networks. Four-wheel steering and a compact body help it reach constrained work sites where large production grinders are unsuitable.
Published references describe operation on Vignole (flat-bottom) and grooved rails, with automated stone positioning through the RML 9000 controller. Dust extraction, spark protection and optional water curtains support work in sensitive urban environments.
Short answer: choose the AT VM 8000 for flexible road access, quick on-tracking and controlled grinding on tram, metro and suburban infrastructure—including curves, switches and short possession windows.
AT VM 8000-8 and AT VM 8000-12E
Eight grinding stones, arranged as two pairs per rail side. This compact configuration is suited to targeted maintenance and constrained urban work.
Twelve grinding stones, arranged as three pairs per rail side. The additional stones support broader grinding patterns and higher treatment capacity.
Exact equipment packages, emissions configuration and homologation depend on build year and operator specification. Confirm the machine serial number before using variant data for procurement.
What work can the AT VM 8000 perform?
Multi-stone passes reduce short-pitch rail corrugation and improve wheel-rail contact conditions.
Controlled metal removal can address early head checks before deeper rolling contact fatigue develops.
The compact road-rail platform and adjustable heads support work through suitable switch geometry.
The machine can remove mill scale and blend suitable rail joints or local surface irregularities.

How does the AT VM 8000 work?
The controller positions grinding stones across the rail head to build the required treatment pattern.
Grinding units cover the gauge corner, running surface and field side within the published angular envelope.
Dust extraction, spark shields and optional water curtains help manage debris and sparks near platforms and streets.
Four-wheel steering and rapid on-tracking allow the grinder to reach multiple work sites without a dedicated rail consist.

120 × 110 × M20L rail grinding wheel
This is the specified wheel reference for the AUTECH AT VM 8000. The product designation uses 120 × 110 × M20L, while the current product-page technical table lists 100 mm thickness; verify the installed wheel marking and approved drawing before ordering.
- Product designation
- 120 × 110 × M20L

Dimensional check required: the product name indicates 110 mm, but the product-page technical table currently states 100 mm thickness. Do not select the wheel from the name alone. Confirm the wheel label, usable thickness, M20L thread direction and engagement, machine RPM and operator-approved drawing.
