in the US often had steps (called "footboard pilots") to allow yard workers to ride with the locomotive. In some countries, footboard pilots are outlawed for safety reasons, and have been removed. Modern locomotives often have front and rear platforms with safety rails, or deeply recessed steps,

Early on, cowcatchers were normally fabricated of bars mounted on a frame; later on, sheet metal cowcatchers were often used for their additional smoothness, and some cast steel cowcatchers were employed for their mass and smooth shape. Early diesel locomotives followed the same plan.
230:. Objects lying on the tram track come in contact with a sensor bracket, which triggers the lowering of a basket-shaped device to the ground, preventing the overrunning of the obstacles and dragging them along the road surface in front of the wheels.

On a mainline locomotive, the cowcatcher has to successfully deflect an obstacle hit at speed. The design principle is to push the object upwards and sideways out of the way and not to lift the locomotive on impact.

Babbage suggested to
Hodgson of the railway company what was later to be called a 'cow-catcher' for sweeping obstacles off the line.
