there have been provided actuating rods 49 which extend from the same towards the front and rear yendsof the engine andv have" their freeends bent to form handles 50, oneof Vwhich will be disposed where it may be easily reached by the engineer or fireman while seated in the cab of theengine and the other of which will be accessible to a member of the engine crew who may be riding near the front of the engine; A `similar abutment may be f mounted upon the rear car of a train, such as f the switch has been set.

the caboose of a freight train, so that trainj men riding in the rear car may move it to an operative position and allow the switch to be v returned to its normalposition from an abutment at the rear end of a train instead of upon the engine after the rear car has passed over the switch. By this arrangement there will be no danger of a switch being returned to the position shown in Fig.V l before all of the cars of a train had passed the switch atthe entrance to a side track. We have,

therefore, provided switch controlmeans whereby a switch at the entrance to a side track may be adjusted inorder to control movement of a train without it being necessary for the train to stop and a trainman leave the train and then again board the train after claim: g i
