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

      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.

      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
