A quick side track down to a dropshaft that feeds the power station infrastructure around here. More of a short detour than somewhere you'd set out for, but worth the few minutes if you're already in the area.

Pull over and have a look inside the concrete building. There's a fair bit of water moving through, so it's an interesting stop and a chance to see the engineering up close.

The track itself is short and easy, good to tack onto a longer day exploring the tracks nearby.
