Battery Locomotives BEV
Zero-emission haulage built for the tight clearances, sharp curves, and constant maneuvering of tunnel construction and shunting work. No exhaust, no added ventilation load, no compromise on pulling power.

Why battery locomotives for tunnel & shunting work
-
Zero local emissions
no exhaust fumes to extract, meaning lower ventilation capacity and running cost in a tunnel where air quality is already a constrained resource
-
Compact, configurable dimensions
cabin height, width, and length adjust to fit your tunnel's clearance profile, not the other way around
-
Precise low-speed control
frequency-converter-driven motors give the fine, responsive handling shunting work demands: tight spotting, repeated coupling, careful positioning around TBM logistics and muck trains
-
Quiet operation
no combustion engine noise, easier on crews working in an enclosed, acoustically harsh environment
-
Tight curve capability
curve radii down to 10 m suit the confined geometry of tunnel sidings and portal areas
-
Manned or fully autonomous
run it with a driver during active construction phases, or automate repetitive shunting cycles once the route is fixed
Technical description
Every battery locomotive is built around maintenance-free, three-phase asynchronous motors from 12 to 110 kW, each with its own frequency converter — giving the precise, independent power control that tunnel shunting needs, where every meter of positioning counts. Power reaches the wheels through a two-axle chassis with interchangeable, rubber-suspended castors, built to handle the repeated start-stop cycles of shunting duty without excess wear.
Safety runs on two independent systems: electrodynamic braking as the primary system, backed by a friction brake for parking — critical in tunnel sections where gradients and limited sightlines leave no margin for error. Inside, a state-of-the-art lithium battery pack with a custom BMS keeps performance and safety in balance, while the driver gets real-time status on an onboard display.
Need it fully automated? Our locomotives are built to run with a driver onboard or completely autonomously — useful once a tunnel's shunting pattern becomes fixed and repeatable.
Basic parameters
We build to your operation, not the other way around. Total weight scales from 4 up to 30 t, with one or two cabins — fixed or removable, sized to fit your tunnel's loading gauge. Track gauge adjusts from 500 to 1,200 mm, handling gradients up to 35‰ and curve radii down to 10 m — tight enough for portal areas and tunnel sidings. Rated for -10°C to 40°C operation.
Low-maintenance by design: premium batteries and a sophisticated frequency converter mean less downtime and lower total cost of ownership — important when access for servicing is itself limited underground.

Our machines in the workshop and in operation
Locomotives & rolling stock for every underground and industrial route
Every tunnel has its own clearance profile, gradient, and shunting pattern. Tell us the constraints you're working within and we'll design a locomotive that fits — literally and operationally.
Need the wagons too? We design and build matching ore cars, passenger cars, and other rolling stock — so you get a complete transport system, not just the locomotive.
