Crossing Mexico in a home-made 'spacecraft'
In the second half of the 19th Century, the Mexican government partnered with British companies to build the railway line that would connect Mexico City with the Atlantic Ocean.
But over the past few decades, Mexico's railways have fallen out of use, leaving hundreds of miles of disused track snaking across the country and cutting rural communities off from the large cities.
Artists Ivan Puig and Andres Padilla Domene decided to build a car capable of travelling on train tracks and explored the country's abandoned railway lines.
Along the way they photographed hundreds of ruins and recorded the stories of the people that they met.
BBC News went to meet the pair as they brought an exhibition about their journey to the UK.
