Travel blogger James Clark has created a subway-style map of southeast Asia that shows every rail line that currently exists, is under construction, or proposed.

What would Southeast Asia look like if it had a fully functioning railway network? I have thought about this many times, usually while on a bus ride from hell (Huay Xai to Luang Prabang springs to mind). […]

Over the years I’ve bookmarked news articles reporting railway lines that are under construction, or have been proposed to be built. Compiling all this data I have created a map of what Southeast Asia could look like if all of those lines were built, combined with current railways.

James warns that he’s included every proposed line, “no matter how ridiculous,” so bear that in mind. It’s also available as a poster. [CityLab]
