Helios is an inflated sculpture suspended from the ceiling of the Churchill Connector station.
It consists of three white horses inspired by depictions of Helios, the personification of the sun god who daily races his fiery chariot across the sky. The horses are made of a coated polyester material that glows in the sun and changes throughout the day with the shifting light.
