How is a train defined in rail terminology?

A train in rail terminology is defined as one or more engines coupled with or without cars. This definition encompasses both freight trains and passenger trains, effectively capturing the various configurations a train can take. It is important because it acknowledges that a train can consist of just the locomotives without any attached cars or can include multiple cars, whether they are for transporting goods or passengers.

This broader definition highlights the versatility of trains in railway operations, as they can be assembled in different combinations depending on operational needs. Recognizing that trains can exist with just engines or with additional cars makes this definition comprehensive and practical for railway operations. It ultimately reflects the functional purpose of trains in the transport industry, accommodating various scenarios encountered during day-to-day rail operations.
