The longest continuous train journey in the world stretches 19,000 kilometres and takes 21 days

The opening of a new line in Laos means Portugal to Singapore by rail is theoretically possible

Train buffs have crowned Portugal to Singapore the longest continuous train journey in the World after a new line in Laos made the connection theoretically possible. Setting off from Lagos those barmy enough to make the journey would pass through 13 different countries on the way, from Spain, Poland and Belarus in Europe to Mongolia, Thailand and Malaysia on the Asian leg of the journey. The opening of a new train line in Laos has made the trip possible. A high-speed rail line connecting Kunming in China to Vientiane, the capital of Laos, means there is now a connection between Beijing and Bangkok with transfers on to Singapore. Travelling from Southern Portugal to Singapore will see you cover 18,755km of the planet. Experts estimate completing the full journey would take 21 days and cost around €1,200. https://twitter.com/Loca1ion/status/1572512982260936708 However, those conscious about their carbon footprint might want to consider it. A one-way flight from Lisbon Portugal to Changi Airport in Singapore would emit an estimated 1.67 tonnes of CO2 equivalents. In comparison, making the long journey by either train would emit roughly 0.08 tonnes. Would you be prepared to do your bit for the environment? Related links:
