Diesel Locomotives ICE
Proven, rugged haulage for tunnel and shunting work where grid power or charging infrastructure isn't an option. Built to run reliably in the harshest underground conditions — heavy load, low headroom, zero compromise.

Why diesel locomotives for tunnel & shunting work
-
Grid-independent from day one
ready to work before any electrical or charging infrastructure is in place, ideal for early-stage tunnel drives and temporary shunting setups
-
Dual independent braking
hydraulic (via the hydrostatic transmission) and mechanical (direct to the castors), with proportional, adjustable brake force for precise control on gradients and in confined sections
-
Built-in safety net
automatic engine shutdown on fault, over-temperature, or over-pressure, plus an automatic emergency brake as backup
-
Choice of engine brand
John Deere, Deutz, CAT, or another brand of your choice, so the locomotive fits your existing maintenance and parts-sourcing setup
-
Wide gauge and curve flexibility
from 500 to 1,435 mm gauge and curve radii down to 10 m, suited to both tight tunnel portals and wider-gauge sidings
Technical description
Every diesel locomotive runs on a 26 to 127 kW water-cooled engine (John Deere, CAT, or your preferred brand), with exhaust routed through a water-cooled exhaust pipe to manage heat in confined tunnel sections. A hydrostatic transmission carries torque smoothly from engine to axle, with a cardan drive shaft powering the second axle — a two-axle chassis built for the repeated positioning shunting work demands.
Braking runs on two independent systems working both axles: hydraulic braking through the hydrostatic transmission, and mechanical braking direct to the castors. Brake force is proportional and adjustable, with an automatic emergency brake as backup. If anything drifts out of range — temperature, pressure, a fault — the engine shuts down automatically. The driver keeps full visibility on locomotive and driving status through the onboard control panel display.
We're prepared to adjust the engine section to your requirements — the engine brand can be your call.
Basic parameters
We adapt the locomotive to your operation, not the other way around. Total weight scales from 4 up to 18 t, with one or two cabins — fixed or removable, sized to your tunnel's clearance. Track gauge adjusts from 500 to 1,435 mm, handling gradients up to 35‰ and curve radii from 10 to 25 m — flexible enough for tight portal geometry through to wider-gauge tunnel sidings. Rated for -10°C to 40°C operation.

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.
