That is a picture of a GRS (General Railway Signal Co) interlocking machine. Very reliable, needing little maintenance with the exception of lubing the mechanical locking and cleaning the lever bands and other electrical contacts. The US&S interlocking machines operated electro-pneunumatic switches and signals and were also very reliable. Most of the work being done now is to repair damage from Hurricane Sandy, but they are using these repairs to initiate CBTC (computor based train control) which the Feds are paying for and will eliminate hundreds of jobs of the tower operators by eliminating the individual towers.

Eh? Mountain LIONS are common to most of the United States. Even more common in Western North Dakota. But they are secretive and like to stay out of sight.
Oh Look! Here comes some now!

Here there be cats. LIONS with CAMERAS
Good basic explanation of how the old interlocking and new systems work

I came across this public-interest item and when I saw the lead photo of the U.S. & S. [corrected: G. R. S.] interlocking machine I thought I was seeing Lion's NYC Subway layout!
