Using data pulled from Twitter, user @danielongz has created an interactive graphic that allows anyone to check on the performance of each MRT line since 2011.

It parses everything from sources of delay to mean distance travelled between delays, with a focus on the frequency of delays.

Try toggling around and have some fun with it (wait a while for it to load though):

How accurate?

The graphic states upfront that there could be gaps in the data.

This is so as the results were assembled using tweets about delays.

In other words, if the delay happened but there were no tweets or the tweets did not state the origin or destination of the delay, this means the delay would not be registered.

But hey, that's the nature of statistics.

Interestingly, the data does correspond to the Land Transport Authority's claim that trains are getting more reliable, as it shows an increment in mean distance before the next major delay (more than 30 minutes) occurs, especially so for the North-East (Purple) Line.

Another fun fact we learned (maybe not very fun for the people living in Bukit Panjang): Bukit Panjang LRT has had more than 18 delays that lasted for more than 30 minutes in 2016.

Note that the top half of the graphic reflects only major delays, while the lower half reflects data for all lengths of delays, except for those on SBS Transit lines.
