Thanks for the picture!
Questions:
Where did this piece of equipment start its career? Nowadays, what with global warming and all, it's hard to imagine a railroad in Connecticut needing this serious a plow (though maybe in places where, because of the way the wind blows around the landscape, snow accumulates...), but in an old-fashioned winter...
And thanks for including the data panel with the plow's weight? When it was built (I'm guessing early 20th C), 40 tones on four axles was quite respectable, and you want a plow to be heavy enough not to derail easily. Were any plows built with space to accommodate temporary ballast, so they could be run light on poor track but heavier on main lines? (How about building the plow onto the end of a hopper car?)
