The railway switching machine of claim 3 , wherein the processing unit is programmed to log a quantity of said movements of one or both of the first point detector bar and the second point detector bar between said first and second positions along with one or more of: a time duration required to compete each of said movements and a current draw of the switching machine during one or more of said movements.
7. The railway switching machine of claim 6 , wherein the processing unit is further programmed to compare one or more of the time duration and current draw to a predetermined value and provide a signal if the comparison satisfies a predetermined condition.
8. 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.
