This is a close cousin of radio. It operates on the closed circuit principle which is so fundamental in railroad signaling, so that any failure of the apparatus, either wayside or on the engine, causes a restrictive indication and stops the train unless the engineman acknowledges.\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:bold;font-style:normal;text-decoration:none;\"\u003eTo obtain two indications on the engine, a clear and a restrictive, a series circuit is used. This is shown in the upper of our two sketches. A radio frequency current is fed into the rails at the head end of the block. If no train is in the block this current does not complete its circuit. If a train is in the block, as shown, the circuit is completed by the wheels and axles. If the signal ahead indicates danger the current is cut off at its source.\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:bold;font-style:normal;text-decoration:none;\"\u003eUnder the pilot of every locomotive running in cab signal territory are a pair of coils, one over each rail. These are wound in opposite directions, so that they pick up this radio frequency current from the rails. An amplifier brings it up to such strength as will work the locomotive apparatus, and as long as the current is received the cab signal indicates clear. A broken rail, an open switch, a train in the block ahead or in the same block, will all cause the current to stop and the signal will indicate stop.\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:bold;font-style:normal;text-decoration:none;\"\u003eIf a third indication is wanted, a parallel circuit through the rails is added as shown in the lower sketch.

There are bridges where ties are bolted directly to the bridge structure and grade crossings where the elevation is determined by the street or highway structure. When it comes to re-ballasting the track is not touched at these permanent locations, but for 100 ft. or so on each side of them the ballast is removed on each side of the tracks and between multiple tracks. Then the old ballast from between the ties is shoveled over into the ditches so formed. New ballast is added in such quantity that the track goes gradually up grade to the new elevation. This grade on each side of a permanent structure is called a runoff.\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\u003cbr\u003e\n\n\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003e\n\u003chr align=\"CENTER\" size=\"3\" width=\"100%\"\u003e\n\u003cfont face=\"Arial\" size=\"3\" color=\"#FFBBBB\"\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.
