How can a locomotive pull so much weight?

Why railroads are making freight trains longer and longer?

Transporting more freight on one train helps to maximize locomotives, crews, fuel and other resources, and trim labor and diesel expenses. It also enables the railroads to reduce the number of trains on their networks, creating more space on certain route segments for additional traffic.

By placing DPUs throughout the train rather than just at the rear—thus distributing power more evenly—railroads were able to enhance a train’s carrying capacity. Computers in both the lead unit and remote units also allow an engineer to coordinate braking and acceleration, as well as redistribute power as they see fit.
