Light-rail passenger trains that provide transportation within and between cities are capable of modest accelerations. The magnitude of the maximum acceleration is typically 1.3 m/s ^2, but the driver will usually maintain a constant acceleration that is less than the maximum. A train travels through a congested part of town at 6.0m/s . Once free of this area, it speeds up to 14m/s in 8.0 seconds. At the edge of town, the driver again accelerates, with the same acceleration, for another 16 seconds to reach a higher cruising speed.
