On a number of occasions during the 1990's the C&TS chose to fire up the OY rotary snow plow to open the line over Cumbres in the Spring.  These events turned into dramatic photo ops, drawing hundreds of on lookers, and generating lots of TV news coverage (and free nationwide publicity) for the railroad.  But plowing Spring snow, much of which turns to ice, was not only tough on men and equipment, but also not cost effective.  Moreover, when 484 derailed on ice and almost ended up on its side in 1999, C&TS management became concerned about the safety of snow clearing operations. So the OM and OY  sat cold and silent for 23 years    But in 2019 the C&TS decided it was time to run the rotary again, only this time for demonstration and training purposes, and in the winter when the snow was lighter. So preparations began and on February 29 and March 1, 2020 OY once again plowed snow to Cumbres.  This album is a collection of photographs from four different rotary events: 1991, 1995, 1997, and 2020.
