Switch Maintenance
A railroad signal maintainer performs adjustments on a track switch during a routine inspection. A model 5H switch machine is used for this installation. The maintenance involves, among other things, a confirmation that the switch points and other components move within a relatively narrow tolerance. Too little pressure on the points, or misalignment of components by a fraction of an inch can result in a derailment.
The model 5H had previously been produced by General Railway Signal, but that company has since been acquired by Alstom Signals. The full operating and maintenance manual can be found here:
