The longest train route in the world starts in southern Portugal in Lagos, making its way through Spain on towards Paris.

The Lisbon-Hendaye route is currently suspended due to Covid-19 and doesn’t seem to be coming back anytime soon. There are alternate routes to get to Paris. e

After Paris, you’ll head through the rest of Western Europe until the journey reaches Eastern Europe and Russia with the famous “Trans-Siberian” railway line taking around 6 days from Moscow to Beijing and covering Mongolia on the way.

Next, you’ll go from Boten to Vientiane, Laos after a long journey through China. The new railroad just opened on Dec 3, 2021.

Before this, you would have had to take a train to Saigon, but no railroad connects Vietnam and Thailand. The old way to make this journey is from a bus through Cambodia and on to Thailand.
