How to get Cable Component to stay in initial position at beginning of simulation?

Hello. I am trying to use Cable Component to make loose cables in the back of a Subway station bounce as the train passes by them.

The issue I am having is that the cables bounce at the beginning of the simulation.

The video is here: Subway Cable Test - YouTube

I have the cables keyed to bounce after the train passes them in the Sequencer, but not at the beginning of the simulation.

How can I get the cables to sit still in all the beginning frames and only bounce after the subway train passes them?

Thanks!
