HOW WIDE THE TRAIN IS MAKES A DIFFERENCE
Unlike air traffic controllers, train dispatchers are responsible for the safety of excessive dimension shipments. Train dispatchers must protect opposing wide loads from each other. The 1000 foot 5 mile buffer is constant for airplanes of all sizes but often the spacing of adjacent tracks precludes the meeting or passing of excess width cars. In some cases, dispatchers must issue instructions to prevent collision of excessive dimension loads with stationary objects such as bridges or tunnels while in others the train crew informs the dispatcher of restricted routes of travel. Regardless, the train dispatcher must remember to keep the train with excessive dimension cars off of the restricted tracks and to include that information in strategic and tactical planning.
