While the UK does not use the specific term "bullet train" (which refers to Japan's Shinkansen), London is the hub for High Speed 1 (HS1), the country's first and only true high-speed rail line. This service operates out of St. Pancras International Station. From here, you can catch the Eurostar, which reaches speeds of 186 mph (300 km/h) as it travels through the Channel Tunnel to Paris, Brussels, and Amsterdam. Additionally, the Southeastern High Speed "Javelin" trains use this line to connect London to Kent at speeds of up to 140 mph. For the future, London is also the starting point for High Speed 2 (HS2), which is currently under construction at Euston Station. HS2 is designed to eventually connect London to Birmingham with state-of-the-art trains capable of reaching 225 mph. So, while you won't find a Japanese-made bullet train in the UK, St. Pancras is your destination for the "closest equivalent"—a high-speed, international rail experience that significantly outpaces the standard 125 mph "InterCity" trains found elsewhere in the British rail network.
