Anti-rollback click faster/louder at top?

[Screaming Coasters]

If you listen closely, there is a separate interfering bang which is the sound of the chain dog. You'll notice this more on older coasters with unprotected setup. Old Arrows, Vekomas and Intamins, etc.

I'm only hearing the lift motor and the anti-rollback.

If they are making a sound, it's not the loud clanks that I was talking about.
