Page "Wagonway" Paragraph 22

The transition from a wagonway to a fully steam powered railway was a gradual evolution.

Railways up to 1835 that were steam powered often made runs with horses when the steam locomotive were unavailable.

The Baltimore and Ohio Railroad, which initially opened in 1830 with of track, was horse powered.

Railroads powered by stationary engines and cables ( San Francisco cable cars ) and horse-drawn trams ( Isle of Man, Douglas Bay Horse Tramway ) are still in use today.
