Re: High-voltage track circuits

["Robd" <robd74@hotmail.com>]

The Steam Ranger line is a low budget tourist rail, maintained and operated
by volunteers, so no the rail would not have maintenance moves over it, the
drivers just approach all crossings with caution. However on our
metropolitan system, we run railcars after a strike to clean the corroded
rail, the old Red Hens were perfect for this task but there are no more in
service. The 2000 & 3000 classes are used, although they cause there own
problems with lack of weight and too good a movement on the track (rides
perfectly on track, whereas older trains would crab walk and shake). We have
wrong side failures on a normal day due to the new design of trains. Hence
the importance of rail grinding or track profiling. Anyway I hope this
trivia could be of use to you.
