Ah, you’re clever. You’re thinking, “Can I take a boat? A bus? A magic carpet?” Well, yes. You can take a Thames Clipper river bus. It drops you at the Battersea Power Station Pier. But that’s cheating. Real tube lovers stay underground.
Also, don’t confuse this with the Overground. There’s a station called Battersea Park on the Overground, but that’s a different Battersea. That one has a park. This one has a giant, iconic power station. Very different vibes.
So, to answer your burning question: it’s the Northern Line. Specifically, the Kennington-to-Battersea extension. Memorize that. You’ll sound like a genius at the pub when someone asks.
A quick reality check
Is it always that simple? No. Sometimes, the train decides to play hide-and-seek. You might wait six minutes instead of three. That’s still better than the Hammersmith & City Line (which, let’s be honest, is a mythological creature at this point).

And if you’re coming from Zone 1? Good news: Battersea Power Station is in Zone 1. Wait, what? Yes, it’s technically Zone 1. But your wallet won’t cry too much because it’s a new station. TFL tried to be nice. It didn’t last.
