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:
“Success goes thus invariably with a certain plus or positive power: an ounce of power must balance an ounce of weight.”
—Ralph Waldo Emerson (1803–1882)
“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)
“The inability to control our children’s behavior feels the same as not being able to control it in ourselves. And the fact is that primitive behavior in children does unleash primitive behavior in mothers. That’s what frightens mothers most. For young children, even when out of control, do not have the power to destroy their mothers, but mothers who are out of control feel that they may destroy their children.”
—Elaine Heffner (20th century)
