METHOD AND APPARATUS FOR OPTIMIZING A TRAIN TRIP USING SIGNAL INFORMATION
First Claim
1. A system for operating a railway network comprising a first railway vehicle during a trip along track segments, the system comprising:
- a first element for determining travel parameters of the first railway vehicle;
a second element for determining travel parameters of a second railway vehicle relative to the track segments to be traversed by the first vehicle during the trip;
a processor for receiving information from the first and the second elements and for determining a relationship between occupation of a track segment by the second vehicle and later occupation of the same track segment by the first vehicle; and
an algorithm embodied within the processor having access to the information to create a trip plan that determines a speed trajectory for the first vehicle, wherein the speed trajectory is responsive to the relationship and further in accordance with one or more operational criteria for the first vehicle.

Abstract
One embodiment of the invention includes a system for operating a railway network comprising a first railway vehicle (400) during a trip along track segments (401/412/420). The system comprises a first element (65) for determining travel parameters of the first railway vehicle (400), a second element (65) for determining travel parameters of a second railway vehicle (418) relative to the track segments to be traversed by the first vehicle during the trip, a processor (62) for receiving information from the first (65) and the second (65) elements and for determining a relationship between occupation of a track segment (401/412/420) by the second vehicle (418) and later occupation of the same track segment by the first vehicle (400) and an algorithm embodied within the processor (62) having access to the information to create a trip plan that determines a speed trajectory for the first vehicle (400), wherein the speed trajectory is responsive to the relationship and further in accordance with one or more operational criteria for the first vehicle (400).
