Problem statement

Transport systems such as the London Underground move an enormous number of people in comfort and safety between a large number of stations.

 To achieve this, a knowledge of where trains are and how fast they are moving is vital to ensure that a reliable timetable is kept, and that trains are spread safely throughout the network. How can the equations of motion be used to plan such a transport system?
