AC86 Scotsman: A Revolutionary Steam Locomotive

The AC86 Scotsman is an iconic steam locomotive that has captured the imagination of railway enthusiasts worldwide. Built in 1923, it is one of the most powerful steam locomotives ever constructed and holds the record for the longest non-stop run by a steam locomotive.

Key Features and Specifications

The AC86 Scotsman is a Pacific class locomotive, meaning it has four leading wheels, six driving wheels, and two trailing wheels. It weighs 145 tons and has a maximum speed of 90 mph. The locomotives boiler is capable of generating 2,500 horsepower and can produce up to 35,000 pounds of tractive effort.

Innovative Design

The AC86 Scotsman was designed by Sir Nigel Gresley, Chief Mechanical Engineer of the London and North Eastern Railway (LNER). Gresley incorporated several innovative design features into the locomotive, including a high-pressure boiler, a superheater, and a mechanical stoker. These features significantly increased the locomotives efficiency and power.

Record-Breaking Journey

In 1934, the AC86 Scotsman made history by completing a non-stop run from London to Edinburgh, a distance of 392 miles. The journey took 8 hours and 3 minutes, setting a world record that has never been broken.
