Locomotives are the mighty machines that make trains go! From the earliest steam engines puffing smoke to today’s super-speedy electric trains, locomotives have been powering railways for over 200 years. They’re more than just engines… they’ve changed how people travel, how goods are delivered, and how the world works.

On 27th September, 2025 the 200th anniversary of modern railway will be celebrated! Find out more about Rail200 here!

We’re going on a journey through some of the coolest and most famous locomotives in history. You’ll learn about record-breaking trains like the Mallard, legendary engines like the Flying Scotsman and even hardworking machines that keep the tracks in tip-top shape. So, grab your ticket, and let’s dive into the fascinating world of locomotives!

1. Locomotives are the powerhouses of trains.

The locomotive is the engine that pulls (or pushes) the rest of the train, carrying people and goods to their destinations.

Locomotives can run on steam, diesel or electricity, and they’ve been powering trains for over 200 years.

2. The Rocket was the world’s first famous locomotive.

The Rocket, built in 1829 by George and Robert Stephenson, looked more like a kettle on wheels than today’s sleek trains. But it was a star!

It won a big race called the Rainhill Trials by going a whopping 30 mph, proving steam engines were the future of transport

3. Mallard is the fastest steam locomotive ever.

The Mallard is a record-breaking train that zoomed at 126 mph in 1938.

It was painted a shiny blue and had a streamlined shape that made it look like it was built for speed.

Even today, no other steam train has beaten its record!

4. Flying Scotsman was the first train to hit 100 miles per hour.

The Flying Scotsman is like the celebrity of trains. It was the first steam locomotive to officially go 100 mph back in 1934.

With its classic green paint and famous name, it’s traveled the world and is loved by train fans everywhere.

5. Deltic locomotives had unique triangular engines.

The Deltic diesel locomotives of the 1960s weren’t just powerful – they were cool!

Their engines were shaped like a triangle and they made a loud, roaring sound that made them hard to miss.

These trains were built to haul heavy loads at high speeds.

6. The InterCity 125 revolutionised train travel.

When the InterCity 125 hit the tracks in the 1970s, it changed train travel forever.

It was the fastest diesel-powered train in the world, zooming along at 125 mph. Its speed and comfort made it the favourite for passengers travelling long distances.

7. Azuma trains are the future of railways.

The Azuma is a sleek, modern train that’s making train travel faster and greener.

These new trains can switch between electric and diesel power, making them more eco-friendly.

Plus, they have Wi-Fi and comfy seats which are perfect for long journeys.

8. Thomas the Tank Engine is one of the most famous trains in the world!

Who doesn’t love Thomas?

This bright blue locomotive is the star of stories and TV shows where he learns to be a really useful engine on the Island of Sodor.

Thomas and his friends teach important lessons about friendship, teamwork and kindness.

9. 08 Shunters are train yard workhorses.

The 08 Shunter may not be as fast as other locomotives, but it’s incredibly strong!

These small diesel engines are used in train yards to push and pull carriages into place.

They’re like the forklifts of the railway world, always busy behind the scenes.

10. Tamping machines keep train tracks safe.

Tamping machines don’t pull trains, they take care of the tracks!

These clever machines lift and pack the gravel (called ballast) under the railway sleepers to keep the tracks level.

Without them, trains wouldn’t run as smoothly or safely.
