I know it's been ages I've been away from almost all sorts of social media (including the fediverse! blame the cold) but...
a relation of a lengthy bus route?!
Dear me, I should have mapped one too (the Kuala Lumpur to Alor Setar bus route, ~450km)

This was the time when (diesel) trains were slower than anything on the road.
Now if I have to get to Kuala Lumpur... it's definitely electric trains! Choo choooooooooooooo!
