This is an update for the Singapore MRT. I created a new logo that reflects the main line in the MRT that both includes an S and a hint at a yin-yang sign. 

 

The type is kept simple and legible, since read-abilty is the main priority. 

 

Along with the logo I have created a map, companion symbols, MRT cards, and placement of both the map and logo. 

 

Directly below are the current logo and map for the Singapore MRT.

The two photos below are not my original images but have been used as placeholders to show application of my map and logo.
