During May 2010, ground was broken at the site, marking the official commencement of the construction phase of the new project. By the end of September 2010, a temporary train station had been opened to accommodate the diversion of passenger services; the old station concourse was closed on 1 October 2010. The first phase of construction was focused on the main station building itself, which is features a one-story hall featuring multiple ticketing counters and information desks, along with 31 retail outlets and trade points, a spacious waiting area for passengers, and compressive closed-circuit television coverage across the complex. As designed, it is to be suited for being simultaneously used by up to 5,000 passengers at any one time, and serve an estimated 12 million visitors per year. The demolition of the old main hall was performed between 22 December 2010 and 11 January 2011. The main station hall was originally scheduled for completion by May 2012; however, the new one-level station hall was eventually opened during October 2012, several months behind schedule.
