From information signboard:
Rotary snow-plough Xrot m No 100 Rotary Gotthard Railway GB 1895
The snow-plough body contains the boiler and a twin-cylinder steam engine driving the bucket wheel, which is nearly 3 metres in diameter. The cutting blades were adjustable to cope with the varying hardness of the drifts. The jet of snow that was hurled away could be directed as far as 90 m sideways and up to 18 m in height. This patent was developed by Leslie Brothers for the Rocky Mountains in North America, and was superior to competitive products available there.
What a beautiful old train, and that plough is fascinating! I need one for our laneway.
It is huge, I was quite intrigued by it.
I grew up in a railroad family and never seen anything like that.
Coffee is on
It was a new one on me too!!
I think this will give a grand sight when this snowplough is doing its job
I never saw a thing like this, what a great design 
I was fascinated by it, the photo doesn’t give justice to how big it was!!
Wouldn’t want to be caught in that thing.
Nor me!!
Wow, I have never seen anything like this before!
Like a time machine.
That thought adds intriguing possibilities
must have been a brute of a steam engine. i like the bull head up there.
The bulls head seems to be making a statement
What an interesting snow plow.
I meant plough!!
I found it a fascinating bit of equipment
