Positive Train Control
Positive train control systems can be overlaid onto cab signal systems or can replace them altogether. These include the Incremental Train Control System (ITCS) installed by GE on the Chicago-Detroit route in Michigan and the North American Joint Positive Train Control (NAJPTC) system being testing in Illinois on the Chicago-St. Louis route. The ITCS has been in revenue service since 2002 with speeds up to 90 miles per hour (140 km/h). Other systems include Alaska Railroad's CAS, CSX's CBTM, and BNSF's ETMS and V-ETMS manufactured and installed by Wabtec.
