Also, even granting that a can't be improved, there must be many factors other than L/V and V/a involved in current train intervals.Say L is 500 feet, V is 50 feet per second, and a is 5 ft/sec^2. Then L/V + V/a is 20 seconds, and yet the interval between trains is 120 seconds. So a little more increase in V/a wouldn't be that harmful. |
