The locomotives in the runaway train themselves (the red units) are General Electric AC4400's. The Locomotives used by the protagonists (the blue units) are older Electro-Motive Division (GM) SD-40-2's.
the largest moving object is a train I believe the largest man made moving object is a oil tanker called the Jahre Viking which has a dead weight of 564,763 tons and is so big it can't navigate through the English Channel, it carries a cargo close to its own weight. The longest man made moving object was train making a one off train journey in Australia consisting of 8 AC6000 locomotives pulled 682 wagons loaded with iron ore, the train weighed circa 100,000 ton and the cargo weighed about 80% of this weight. The train was 4.6 miles long The largest manmade moving object on the earth is a oil and gas seismic survey vessel called the Ramform Viking and is produced by PetroGEO Services (PGS). And it collects more than 1.12 Terabytes of seismic survey data per day. The surveyor with its 10 streamers at 120 m separation is more than a kilometer wide and more than 8 km long covering a surface area of 8.75 km2 at any time. Moving at a speed of 4.3 knots it is covering a total surface area of 215 km2 per day in full production. It represents the largest moving object on the face of the earth, bigger than any seismic spread ever deployed and bigger than anything else moving on land or at sea.

The largest moving thing made by human hand is the International Space Station (ISS). It orbits Earth at around 28,000 kilometers per hour and acts as a research laboratory for scientific experiments conducted in microgravity.
The world's largest man-made monument is the Great Wall of China, which is, in fact, a series of great walls. It was built at various stages between the 6th century BC and the 16th century to protect the northern borders of the Chinese Empire. Including all the sections, the Great Wall extends for over 6,700 km in total.
