Train breakdown along CCL on Saturday evening, massive confusion for passengers affected by service disruption

Train service was disrupted along the Circle Line (CCL)  on Saturday evening due to signaling fault, starting with trains being stuck between Tai Seng - Mac Pherson stations, and Paya Lebar - Dakota stations.

About 6pm tweets from affected and worried passengers started to post questions about their stalled trains on the social media platform:

Not long after, TYH complained why trains not serving the affected stations were also not moving; and Mark Zuckervurg explained it was a domino effect:
