Directional MRT maps inside the trains of Taipei

Inside the supremely efficient MRT train on the right hand side was a map showing the stations along this route (blue line), and also the interconnecting red and green lines. All seemed straightforward until I turned around to face the left side of the train where I was puzzled by a somewhat different looking map. Was it the same map? Was it a mirror image or rotated 180 degrees? Actually, it was something quite different.

The confusion was caused by the fact that the both maps faced each other and yet still showed the direction that each line crossed. E.g. travelling along the blue line from Shandao Temple, when the train crossed the red line the map correctly showed that the Zhongshan would be found if you headed right. For the maps to work, each had to show this correctly. Unfortunately this didn’t do much for my mental map of the Taipei MRT system.
