On Monday July 8, 2013 Sabino SP970 was cut in. Two Main tracks now extend from Marana SP961 to the east end of Kino SP976
The west end of Kino SP974 was retired. The old Main track was realigned to the new track 1 and the old siding was lined with the old Main track.
New signals were put in service at both ends of Rillito.
Interesting observation, with Sabino having 50 MPH movable point frog switches and Kino with a slow ridged frog 30 MPH switch, unless traffic decrees something else most traffic uses Sabino as the end of two tracks.
