Terminology for a Group of Trains

In the realm of rail transportation, the term "fleet" is commonly used to describe a group of trains operated by a particular railroad company or organization. This collection of trains, often consisting of multiple locomotives and passenger or freight cars, serves a specific purpose within the railway system, such as transporting passengers, hauling freight, or performing maintenance and repair tasks.

The size and composition of a train fleet can vary significantly depending on the railroad's operations and the specific services it provides. Some railroads may operate large fleets of hundreds or even thousands of trains, while others may have relatively small fleets tailored to their specific needs. The type of trains included in a fleet can also vary, with some railroads specializing in passenger transportation, while others focus on freight hauling or a combination of both.
