The clock, built by US manufacturer Electric Time Company, has a diameter of six meters and is decorated with only the number 9, in memory of King Rama IX.
The Bang Sue station, whose construction is underway, will replace the Bangkok railway station (Hua Lamphong) and will also be the biggest train station in Southeast Asia when completed. Construction began in 2013 and it is scheduled to open in 2021.
The station consists of 26 platforms, which includes 24 platforms of the State Railway of Thailand and two platforms of the Mass Rapid Transit Authority of Thailand.
