Underground Mining Locomotives, Built for Your Track
Not for a catalog.
AMAC underground mining locomotives move ore, materials, and crews across your mine on rail, quickly and safely. We design, build, repair, and rebuild custom mining locomotives for coal and potash operations across the US and Canada, engineered to your track gauge, grade, and haulage distances.

— The Lineup
Our Underground Mining Locomotives
AMAC builds underground mining locomotives in the 20 to 25-ton class for 42-inch gauge main-line haulage, and rebuilds or retrofits locomotives from any manufacturer. Every build starts from your track gauge, grade, weight class, and haulage distance rather than a standard platform.
Tier III Diesel Locomotive
HA Series Mining Locomotive
A 20 or 25-ton Tier III diesel rail locomotive with a Cummins QSB 4.5 engine, proprietary onboard diagnostics, and tether capability for heavier trains. Built for 42-inch gauge main-line haulage in coal and potash mines.

— The Difference
Built to your track
Backed by over 40 years of underground OEM engineering and ISO 9001:2015 certified operations.
Custom Engineering
We start from your track gauge, grade, weight class, and haulage distances and engineer the locomotive around them, not from a standard platform.
Rebuilds & Retrofits
We repair, rebuild, and retrofit virtually every type of underground locomotive on the market. HA Series systems can be added to an older locomotive as cost-saving upgrades, so you modernize what you already run.
Underground Safety
Every locomotive includes automatic and manual fire suppression, SCSR and first aid storage, automatic sanding, LED headlamps, and a proprietary onboard diagnostics and control system.
