Singapore North East MRT Line (NEL) and Golden Rectangles

The North East MRT Line (NEL) is the third Mass Rapid Transit line in Singapore and the world's first fully-underground, automated and driverless rapid transit line. The line is 20 km long with 16 stations and operated by SBS Transit. Travelling from one end of this line to the other end takes around half an hour. Photo credit: Wikipedia. Post a comment.

A golden rectangle is a rectangle whose side lengths are in the golden ratio, one-to-phi, that is, approximately 1:1.618. A distinctive feature of this shape is that when a square section is removed, the remainder is another golden rectangle, that is, with the same proportions as the first. Square removal can be repeated infinitely, which leads to an approximation of the golden or Fibonacci spiral.
