The scene at Joo Koon MRT station on the first morning of suspension of train services between Joo Koon and Gul Circle stations. Following the train collision last week that was traced to a signaling glitch that struck as a train crossed over from the old signaling system on the East-West Line to a new one on the Tuas West Extension, the Land Transport Authority said train service between Joo Koon and Gul Circle stations will be cut for up to one month to allow for assurance checks. Commuters had to disembark at Joo Koon station and catch bus bridging services to Gul Circle station to continue their commute to Tuas Crescent, Tuas West Road and Tuas Link stations.
