Claims14
A railroad switch assembly for switching a pair of movable rails in relation to at least one running rail, said running rail having a field side, each of said movable rails having a point end and a heel end, comprising:
- a switch machine located on the field side of said running rail;
- a point end switch rod connected to the point ends of said pair of movable rails, said point end switch rod being housed in a first hollow tie;
- a heel end switch rod assembly connected to the heel ends of said pair of movable rails and comprising a heel end switch rod housed in a second hollow tie;
- a front basket associated with said point end switch rod for controlling the throw applied to said point end switch rod said front basket being at least partially housed in a portion of said first hollow tie;
- an assist rod assembly extending between said portion of said first hollow tie and said heel end switch rod assembly, said front basket being operatively connected to said assist rod assembly to actuate movement of said assist rod assembly upon displacement of said basket.
- wherein said front basket is located between said switch machine and said running rail;
- and
- wherein said movement of said assist rod assembly is rotation.
A railroad switch assembly for switching a movable rail or point in relation to at least one running rail, said running rail having a field side, comprising:
- a front basket operatively associated with a front switch rod assembly for controlling the throw applied to said front switch rod assembly;
- a rear basket operatively associated with a rear switch rod assembly for controlling the throw applied to said rear switch rod assembly;
- said front and rear baskets being at least partially housed within respective hollow ties and being located on said field side of said running rail;
- and,
- an assist rod assembly extending between said front basket and said rear basket, said assist rod assembly being rotatable by lateral displacement of said front basket.
A railroad switch assembly for switching a pair of movable rails in relation to at least one running rail, said running rail having a field side and a gauge side, each of said movable rails having a point end and a heel end, comprising:
- a switch machine located on the field side of said running rail;
- a point end switch rod assembly connected to the point ends of said pair of movable rails, and comprising a point end switch rod housed in a first hollow tie;
- a heel end switch rod connected to the heel ends of said pair of movable rails, said heel end switch rod being housed in a second hollow tie;
- a rear basket associated with said heel end switch rod for controlling the throw applied to said heel end switch rod wherein said rear basket is at least partially housed in a portion of said second hollow tie;
- an assist rod assembly extending between said portion of said second hollow tie and said front end switch rod assembly, said rear basket being operatively connected to said assist rod assembly such that said assist rod actuates movement of said rear basket;
- and
- wherein said rear basket is located on the field side of said running rail.
