I sympathise with the maker of this map.
I’m sure if a train lover visits Tokyo, he’ll like this map too
after that.
Shinjuku station has about 10 lines running through it. I doubt
Singapore will ever have so many lines running through one
interchange though.
There are some imperfections to the map. Bukit Gombak area is
not covered properly and the area around Still Road has not very
good access either.
An airport express line might be beneficial instead of the
Changi Airport branch line. But that would be hard to make unless
they are going to share the railroad with the East West line which
may cause problems since the line may be overcongested by the time
Singapore reaches such a high development of train lines.
