The Natur-Park Schöneberger Südgelände is what happens when a railway yard is abandoned and nobody tidies up for thirty years. The trains stopped, the birch moved in, and someone had the sense to let it stay wild rather than build on it. Now it's a park where the conservation idea is the whole point: machinery losing, slowly and deliberately, to the woods.
From Priesterweg, pay the small gate fee and walk in. The brick water tower marks the old working yard; past it, the canopy closes over and a rusting steam locomotive sits half-swallowed by bramble — the photograph everyone takes, and rightly. A raised steel walkway lifts you above the meadow so the grass below is left alone, rail-themed sculptures set along it.
Then just wander. Birch over the old sidings, rails in the grass, the city muffled. Leave by the south and walk the Priesterweg to Südkreuz — wild yard one minute, glass interchange the next. That jolt is the ending.
