Abstract
A railway switching machine includes a housing, a first point detector bar slidably coupled to the housing and structured to be directly coupled to a first switch point, and a second point detector bar slidably coupled to the housing and structured to be directly coupled to a second switch point.
Claims14
A railway switching machine comprising:
- a housing;
- a first point detector bar slidably coupled to the housing and structured to be directly coupled to a first switch point;
- and
- a second point detector bar slidably coupled to the housing and structured to be directly coupled to a second switch point,
- wherein the housing includes a first number of proximity sensors positioned to detect a target provided on the first point detector bar and a second number of proximity sensors positioned to detect a target provided on the second point detector bar, and
- wherein each of the first point detector bar and the second point detector bar are moveable from between a first position wherein the target disposed thereon is positioned at or about a first proximity sensor of the number of proximity sensors and a second position wherein the target disposed thereon is disposed about a second proximity sensor.

A railway switching system comprising:
- a first switch point;
- a second switch point;
- and
- a railway switching machine comprising:
- a housing;
- and
- a first point detector bar slidably coupled to the housing and directly coupled to only one of the first switch point or the second switch point,
- wherein the railway switching machine further comprises a second point detector bar slidably coupled to the housing and directly coupled to the other one of the first switch point or the second switch point,
- wherein the housing of the railway switching machine includes a first number of proximity sensors positioned to detect a target provided on the first point detector bar and a second number of proximity sensors positioned to detect a target provided on the second point detector bar, and
- wherein each of the first point detector bar and the second point detector bar are moveable from between a first position wherein the target disposed thereon is positioned at or about a first proximity sensor of the number of proximity sensors and a second position wherein the target disposed thereon is disposed about a second proximity sensor.
