Now if i may ask, what is this (inside yellow circle) for

Thats a wheel slip detector.Seems like high pressure rail cleaner.
But the dark image within yellow circles hampers me.
What part is it?
For example I depicted the hose and asked for the hose.
If you describe me item or part albeit vaguely, I will tell you.
Thats a wheel slip detector.
i asked the question as its functioning precedes that of sander. It measures ground speed and wheel speed and in case tractive effort exceeds the net adhesive weight, leading to heating damage on wheels and rail, it initiates corrective action. whenever such a condition is detected, sanding is initiated which increases coefficient of friction (f). Since mass of locomotive is fixed, increase in f, increases Adhesive weight (Weight of locomotive x f), thereby reducing or elimination of slippage.
Head, Web and Foot (respectively) of a rail section.
Don't know about these days, but back in my days this used to be a part of engineering drawing lessons.
