Atmospheric Traction Recommended to South Devon
Brunel recommends atmospheric propulsion for the South Devon Railway, expecting savings and greater freedom in gradients and curves.

Historical context
South Devon Atmospheric Railway: overview and significance
What happened?
Brunel adopted atmospheric traction on part of the South Devon Railway. Stationary engines created a vacuum in a pipe between the rails, with a piston connected to the train through a longitudinal seal.
Why was it important?
The system promised quiet, powerful traction without locomotive weight but suffered from reliability and operating-cost problems. Its failure is an important part of Brunel's engineering history because it shows the risks of ambitious technological experimentation.
