Our system of train transport is known as MRT short for Mass Rapid Transit. It is cheap, efficient, clean, and fast, albeit some recent glitches over the last 2 years after running very well for the last 10 over years. If you avoid traveling during the rush hours, you will find yourself lotsa of personal space in the train, even though all the seats would already be taken up, thus it is quite comfortable to sketch. Noone would bother you when you sketch because everyone would be too engrossed with their business; watching Youtube videos, playing games and surfing the net. Once in a while you would see someone reading a book, something very rare here. Anyway these 2 sketches were done standing up. I did the inked lines first and painted later at home. I will try painting on location next time but I have to bring a small setup to do so.
Will bring you more train sketches soon. :D
