Also if you want the variants of this theoretical route, here's how to calculate the distances... assuming that at some point routes via Belarus or Ukraine, and into China open up again...

You need to use the geodisical distance calculator:
gps-coordinates.net/distance

You first need to define: what is a train?

Are we talking heavy rail? Or also trams and metros as well?

If it's heavy rail then starting point is Cascais station, west of Lisbon
Coordinates 38.7007835, -9.4207947

And end point Singapore Woodlands Checkpoint
Coordinates 1.44378, 103.7674213

11904.73 km

If you can use trams and metros you can extend it a little bit - you can use the Elétrico de Sintra from Praia das Maçãs
Coord 38.8258403, -9.4686851

And Singapore Metro Station Changji Airport
Coord 1.3576001, 103.9184495

11923.23 km

Both of these options need a bit of walking - between Elétrico de Sintra station and CP station, and between Woodlands Checkpoint and Marsiling Metro, and for the heavy rail between Alcantara Mar and Alcantara Terra - there may be other short walks too

But - as stated in the earlier thread - these are *theoretical* routes for the moment, as political problems and COVID restrictions mean you can't actually *do* this route currently
