The control of the train is left entirely with the engineer as long as he obeys the requirements of the signal indications ; when he fails to do so, the automatic train control operates and brings the train to a stop. With train control, it is therefore possible to increase the safe running speed of trains and also to decrease the clearance between trains.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv style=\"text-align:left\"\u003e\u003cspan style=\"font-family:Calibri;font-size:1.0em;color:#000000;font-weight:normal;font-style:normal;text-decoration:none;\"\u003eElectric and Pneumatic Equipment.-The automatic train-control apparatus comprises two sets of equipment, the electric and the pneumatic. Under certain conditions the action of the electrical apparatus brings about the operation of the pneumatic apparatus, which then applies the brakes.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv style=\"text-align:left\"\u003e\u003cspan style=\"font-family:Calibri;font-size:1.0em;color:#000000;font-weight:normal;font-style:normal;text-decoration:none;\"\u003eExplanation of Types.-Automatic train control falls into two general types ; namely, continuous and intermittent. The distinction between these two types of control can be understood from the following: Assume that a train moving in the direction of the arrow, Fig. 1, approaches a caution signal; this implies that another train is occupying block 2. As the train passes the caution signal, the cab signal changes from clear to caution. \u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv style=\"text-align:left\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv style=\"text-align:left\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\n\u003cdiv style=\"text-align:left\"\u003e\u003cspan style=\"font-family:Arial;font-size:1.0em;color:#000000;font-weight:normal;font-style:normal;text-decoration:none;\"\u003eAll pictures are of the actual item.  If this is a railroad item, this material is obsolete and no longer in use by the railroad.  Please email with questions.
