NOTES: Transit rail modes are measured in car-miles. Car-miles measure individual vehicle-miles in a train-the movement of 1 vehicle the distance of 1 mile. This differs from a train-mile which is the movement of a train, which can consist of multiple vehicles (cars), the distance of 1 mile. 2006 transit data are preliminary.
