Heathrow Express Celebrates its 15th Birthday by Making a Train Carriage Entirely of Cake

A Heathrow Express train carriage made entirely of cake has arrived at a platform in London’s Paddington station. A dedicated team of 15 specialist bakers and food artists were tasked with creating an edible train carriage, providing a sweet treat for passengers on their way to and from Heathrow. The cake celebrates the 15th anniversary of the Heathrow Express — the fastest way to travel to Heathrow.

The enormous cake — measuring a huge 1.5 x 4 x 2m — consists of 15 ingredients including approximately 80 large sheets of delicious Madeira sponge, which laid end to end would be longer than the length of an Olympic-size swimming pool. These were sandwiched together using 60kgs of traditional buttercream icing, 3kgs of royal icing and over 200kgs of smooth fondant icing. The exterior was held together using a litre of confectioners glue and decorated using half a dozen litres of airbrush paint and 5 litres of liquid chocolate, chosen especially to create the windscreen wipers and intricate carriage markings and signage.
