D66 VARIO

NR drive units that provide the same tractive force regardless of the direction of travel
ULISSES – an innovative, intrinsically safe control system that monitors the locomotive’s parameters
- optional driving modes with intelligent system support
- Operator identification system with customer-specific authorisation levels
- display of error messages in text format
- recording of operating parameters for easy diagnosis
- Simple and robust design
Anti-slip systems to improve the traction of the friction wheels:
- Traction Control System TCS
- Pressure booster – friction pressure control of the drive wheels
- Single-rail rack-and-pinion combination drive system with automatic mode changeover
Compact design
20 hours continuous operation (at average load)
Locomotive configuration for different operating modes: personnel and material transport, shield removal units and shearer loaders

Redundant electromagnetic valve system in the control circuits for braking and motor cut-off.
Automatic fire protection system – also active in engine-off mode.
Mechanical overspeed governor – also active in engine-off mode.
Continuous methane measurement with two-stage detection system.
Drive units located outside the power unit, allowing any configuration of the traction with optimal distribution of traction/braking force.
Low exhaust, heat and noise emissions.
Robust and ergonomic driver’s cabins.
Lighting system with automatic light colour switching depending on the direction of travel.
Additional headlights that increase visibility on the railway line.
