Longest possible train journey in the world now covers over 11,653 miles in total

During a train journey it can be great to look out the interview and take in the sights and you’ll have plenty of opportunities for that on the longest possible train journey.

Sometimes when you are on the train, it feels like the longest journey in the world. But the actual longest possible train journey is probably a lot longer than you might think and will take you further than you would have imagined.

As the trains go across multiple continents, through more than 10 countries and through a ridiculous number of cities, you can see quite a lot of different places.

The trip would see you travel about 11,653 miles and go through 13 countries so things can get quite complicated. The trip takes a total of three weeks and requires seven different visas.

So it's not really something you do on a whim. In fact, to make the most of things and have the most flawless travel experience it probably makes sense to the most amount of planning.

The first train leaves Lagos, in Portugal not Nigeria, and then you are off deeper west into Europe.

From Portugal you head to Spain, France, Russia, China, Vietnam and Thailand before landing in Singapore. Now, getting back I guess you can fly or do the same journey in reverse.

Thankfully it isn’t a non-stop journey, so travelers actually have the opportunity to stop off in some of the cities and explore for the day/night. And amazingly the trip isn’t that expensive, all things considered. It would set you about €1,186.65 ($1,350).

Unfortunately, this isn’t just one train that takes you the entire distance.

When people on social media heard of this trip, they were equally baffled and half excited about the possibilities.

One Twitter user wrote: “As a man I must claim to be able to complete this trip without going pee once.”

Another added: “Imagine realizing halfway through that you left your stove on," as a third wrote: “It could actually be a little bit longer if you continued on the trans Siberian railway and entered China in Manchuria.”

And someone else joked: "Don’t think at the current world affairs one can go via train from Berlin into Moscow anymore…otherwise all correct. Nice route."

Would you consider tackling this mammoth of a trip?
