Sandbox (locomotive)

Index Sandbox (locomotive)

A sandbox is a container on most locomotives, multiple units and trams that holds sand, which is dropped on the rail in front of the driving wheels in wet and slippery conditions and on steep grades to improve traction. [1]

Sandite is a substance used on railways in the UK, Ireland, US, the Netherlands and Belgium to combat leaves on the line,http://www.agrri.org.uk/BRR/docs/TM-TRIB-14%20_A_.pdf which can cause train wheels to slip and become damaged with flat spots.

Slippery rail

Slippery rail or low railhead adhesion, is a condition of railways (railroads) where contamination of the railhead causes trains to experience less adhesion (grip).

Steam locomotive

A steam locomotive is a type of railway locomotive that produces its pulling power through a steam engine.

A tram (also tramcar; and in North America streetcar, trolley or trolley car) is a rail vehicle which runs on tramway tracks along public urban streets, and also sometimes on a segregated right of way.

Wheel slide protection

Wheel slide protection and wheel slip protection are railway terms used to describe automatic systems used to detect and prevent wheel-slide during braking or wheel-slip during acceleration.
