ABSTRACT:
A railroad brake line shutoff valve assembly for connecting a car mounted railway brake line to a brake line air hose. The assembly includes a shutoff valve with a stationary valve portion and a moveable valve portion. The stationary valve portion has a first fluid line attachment site and a second fluid line attachment site. Movement of the moveable valve portion to one position opens a flowpath through the valve between the first fluid line attachment site and the second fluid line attachment site. Movement of the moveable valve protion to another position closes the flowpath through the valve. The assembly includes a junction box having a first set of electric line attachment sites for connection of a set of car mounted electrical trainline conductors mounted on the railway vehicle and a second set of electric line attachment sites for connection of a set of electrical line end segments which terminate in a multiple contact electrical trainline connector. The junction box also has a third set of electric line of at least one of an electronic system or an electrical system located on the railway vehicle. Each member of the first set of electric line attachment sites is electrically connected to a corresponding member of the second set of electric line attachment sites and also to a corresponding member of the third set of electric line attachment sites.
