Many modern diesels have a snow/rock plow equipped pilot. Seems like a good idea.
Why don't all of them have plows? What criteria decides whether or not to equip?
I could imagine that units assigned to yard duty might not need them.
Thanks

They also work extremely well when involved in grade crossing accidents, i.e. deflecting vehicles off to one side many times.

They are expensive.

Whether or not to spend the money for them.

Correct.
Thanks
Thanks. As a modeler I just like the way they look with a "cowcatcher" 
The Western Maryland RWY. used several different plows on their diesels, especially useful considering the rugged territory their trains passed through.
