Discover what’s hiding under Sheffield Train Station as we explore the Megatron – a vast underground Victorian storm drain system. Follow us beneath the city streets into a hidden world of culverted rivers, echoing tunnels, and abandoned urban infrastructure.

In this deep dive, we trace the River Sheaf and Porter Brook from the surface at Pocket Park into the eerie subterranean chambers below Sheffield’s city centre.
