How much pressure to trip arm

[NJTransitFan 0]

How much pressure it takes to move the tripper arm on the subway? I'm assuming the weight of a subway car. Would a human have the force to move or engage the trip arm?

Its definitely the force of a train to move that thing I believe.

What happens is, usually anything in the way of the shoe I guess, cause I think that trips the train, would, could, and will trip the train. Usually happens when a train passes a red signal and hits the trip arm. I would imagine you asked this because of the recent incident in the subway.....

A human can step on the stop arm to make it go down. We do it all the time when we have signal problems with permition from Rail Control Center.

Do you have to put all your weight on it or a casual step would do the trick?

The Automatic is less force but a homeball you need a lot of pressure. The trick is when it don't retain you have to keep presure on the stop arm with you foot and bend down and hook the stop arm down.

Good information there. Not that I'm going to jump down onto the tracks and try it out for myself.

Even if you did and I know you won't the signal will stay at danger until its un hooked.

As a kid I always used to wait for a train to pass so I can see the arm go up I used to get a kick out of it. I was a kid.
