the outside of the train is almost the same as the older c830, with slight differences such as a larger smrt logo and the look of the train inside. the reserved seats are coloured red to make them more obvious. navy blue and yellow coloured seats are installed in the driving motor cars (end carriages) while the seats in the middle car are khaki. the train's system that allows it to move is louder than the c830's, and is identical the one found on the amsterdam metro m5 series.
