Suspended high above the Grand Terrace of St Pancras International, Thought of Train of Thought plays with movement, perception, and reflection. This 18-meter twisted blade of polished aluminum rotates slowly, creating an optical illusion of continuous motion—suggesting the rhythm of passing trains, yet free from tracks and gravity. Minimal and monolithic, yet ever-shifting, the work transforms with light and perspective, offering a moment of stillness in one of London’s busiest transit hubs.
