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.

Famous quotes containing the words positive, train and/or control:
“As for the terms good and bad, they indicate no positive quality in things regarded in themselves, but are merely modes of thinking, or notions which we form from the comparison of things with one another. Thus one and the same thing can be at the same time good, bad, and indifferent. For instance music is good for him that is melancholy, bad for him who mourns; for him who is deaf, it is neither good nor bad.”
—Baruch (Benedict)
“Children must eventually train their own children, and any impoverishment of their impulse life, for the sake of avoiding friction, must be considered a possible liability affecting more than one lifetime”
—Erik H. Erikson (20th century)
“Surrealism, n. Pure psychic automatism, by which it is intended to express, whether verbally or in writing, or in any other way, the real process of thought. Thought’s dictation, free from any control by the reason, independent of any aesthetic or moral preoccupation.”
—André Breton (1896–1966)
