What is a "token"?
A token is a physical object, often a metal or paper piece, used in railway systems to control train movements on single-track lines. It serves as a form of authorization, given to train crews to signal that they are allowed to occupy a particular section of track. When a train operator receives the token, it ensures no other train can enter the same section at the same time, preventing accidents. After passing through the section, the operator returns the token to the station or dispatcher, allowing the track to be cleared for other trains. This system helps maintain safety and order on tracks with limited signaling equipment.
so small or minimal as to be merely symbolic or insignificant
