These are so simple and yet so clever. When i noticed them the first time i started noticing them everywhere (on all rail infrastructure).

I as well. Seattle transit, NEC Amtrak and NJ transit live off of these. If these systems work for them, they'll work for us all

Is it simple? It looks quite complicated, but maybe that's just me forgetting how to compute forces.

simple in that it's just a clever series of wires and pulleys, not some sort of digital adjustment device, i suppose

Also, you are looking at a few different wires at once here. Each separate wire is tensioned with a mechanism with a few moving parts.
