Train

A train is a series of connected railway vehicles that travel on tracks and are used to transport passengers or freight.

Updated September 11, 20261 min readCited sources

A train is a series of connected railway vehicles that travel on tracks to move passengers or freight. Most trains are pulled by a locomotive, though some are self-propelled.

What it is

A train consists of coupled vehicles running on steel rails with a fixed gauge. The low friction of steel wheels on steel rails makes trains efficient for moving large loads. The word comes from Old French *trahiner*, meaning 'to pull'.

Types and uses

Trains are classified by purpose: passenger trains carry people, freight trains carry goods. Propulsion varies—steam, diesel, electric, or self-propelled multiple units. Regional terminology differs; in Canada, 'train' also historically refers to a long sleigh for hauling goods in winter.

Why it matters

Rail transport is a key part of Canada’s transportation network. Trains offer an energy-efficient way to move goods and people across long distances, reducing road congestion and emissions.

In short

  • Trains are connected vehicles on railway tracks for passengers or freight.
  • Most use steel wheels on steel rails for low friction and efficiency.
  • Passenger and freight trains serve different purposes.
  • Rail transport is important in Canada’s infrastructure.
Canadian angle

Rail transport is part of Canada’s transportation network, and the term 'train' is also used in Canadian English for long connected rail vehicles and, historically, for a long sleigh used to haul goods in winter.

Quick questions

What is a train?
A train is a connected series of railway vehicles that travels on tracks to carry passengers or freight.
How are trains powered?
Many are pulled or pushed by locomotives, while others are self-propelled, such as multiple units or railcars.
Why are trains efficient?
Most use steel wheels on steel rails, which produces low friction and helps reduce energy loss.
