I thought this was a pretty neat video of a restored Steam Powered rotary snow plow pushed by two steam engines on the Cumbres and Toltec scenic railroad on the New Mexico and Colorado border.  The two pusher engines lose traction quite often pushing the plow up the 4% grade.   I have been on the trip a couple of times but it was during the summer and no snow.  Hope you enjoy it.  All the equipment is about 100 years old.

 
 

Thanks for posting that D4Jim. Excellent movie and well presented by the railroad.

GOOD JOB. THANK YOU FOR POSTING!!
