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:
“It is easy and dismally enervating to think of opposition as merely perverse or actually evil—far more invigorating to see it as essential for honing the mind, and as a positive good in itself. For the day that moral issues cease to be fought over is the day the word “human” disappears from the race.”
—Jill Tweedie (b. 1936)
“Anyone who has a child today should train him to be either a physicist or a ballet dancer. Then he’ll escape.”
—W.H. (Wystan Hugh)
“To try to control a nine-month-old’s clinginess by forcing him away is a mistake, because it counteracts a normal part of the child’s development. To think that the child is clinging to you because he is spoiled is nonsense. Clinginess is not a discipline issue, at least not in the sense of correcting a wrongdoing.”
—Lawrence Balter (20th century)
