Trains to Paris could soon get cheaper. Here’s why

• Double-decker trains are being considered for the London-Paris route through the Channel Tunnel.
• Alstom, the manufacturer of the Avelia Horizon, the world's only high-speed double-decker train, has confirmed discussions with several operators, including Eurostar and potentially Virgin Group.
• The move could significantly increase passenger capacity on the route.
• The Avelia Horizon can reach speeds of up to 200mph and would have a lower cost per seat than single-decker models, former Alstom CEO Henri Poupart-Lafarge said.
• While the trains would need regulatory approval, which could take years, they are compatible with the Channel Tunnel's infrastructure.
