Abstract

In 1995, General Electric began development of the incremental train control system (ITCS) for Amtrak to use on its Michigan corridor between Detroit and Chicago. The main aim for ITCS was to allow Amtrak passenger trains to operate at 110 mph intermixed with freight traffic. To achieve this goal, the traditional wayside signal system would be enhanced with a positive train control (PTC) system to enforce the wayside signal indications (train movement authorities) and operating speed limits. Additionally, the highway-rail grade crossings had to provide the required warning time for trains operating at higher speeds than for what the crossings had originally been designed for. This article provides an overview of ITCS, a failsafe PTC system that overlays the existing signal system for improved safety and provides a cost-effective solution for high-speed train operation.
