I might have lied when I said interestingly.
Can you illustrate the various types of power controllers in use, and traction motor technologies? I'm quite good at picking them out by sound, and can put a dinner party to sleep recounting them.
Errr, I might have used the same way you did, actually.
You might see the knob move when the brakes are functional as the pressure increases.
They are evident so that the driver can inspect them in a hurry if there is a snag with the brakes -- as the hand would show pressure where perhaps there shouldn't be any.

If you maintain it relatively well, an electric train will nominally keep going forever. (The Buenos Aires metro has just completed phasing out the last of the original rolling stock from Line A, which, at its withdrawal, was 100 years old in standard revenue service.)
