Are there gears in trains?

Trains do have gears, but they just have different names based on the type of engine used. A diesel locomotive has eight gears called notch. The gears work similar to those in cars or bikes where the speed of the locomotive increases with every gear change.

Modern locomotives use electric traction instead of gears as electric traction is much more flexible than gears. Diesel fuels generators from the combustion engine and transform the energy using an alternator, which runs the traction motors.

One locomotive weighs about as much as 108 hippos Tier 4 locomotives weigh a whopping 432,000 pounds — the same as 108 hippos weighing in at 4,000 pounds each. These 6-axle engines have 4,400 traction horsepower and can reach a maximum speed of 70 miles per hour pulling thousands of tons of freight.

Biodiesel & Renewable Fuels: Traditionally, locomotives have run on petroleum diesel fuel, but railroads are now using renewable diesel and biodiesel blends to power them. Both renewable diesel and biodiesel are made from renewable energy sources and don't rely on fossil fuels.
