Real trains are manufactured in a multi-stage process, starting with design and contract signing, followed by material procurement, manufacturing, assembly, testing, and finally, delivery into service. Trains work by converting energy (from sources like electricity, diesel, or steam) into mechanical power, which then drives the wheels along the tracks, allowing the train to move forward. Train speeds vary greatly depending on the type of train, track infrastructure, and location, ranging from around 40-50 mph for freight trains to over 200 mph for high-speed trains like bullet trains. Bullet trains, also known as Shinkansen in Japan, typically operate at speeds of around 320 kilometers per hour (200 mph), though some test runs have reached even higher speed.
Trains, including both their tracks and bodies, are primarily made of steel and steel alloys, with aluminum increasingly used for lighter and faster train cars. Trains can achieve high speeds due to a combination of factors, including streamlined designs that minimize air resistance, dedicated tracks that allow for smoother travel, and powerful engines that can maintain high speeds efficiently.
