Apart from the city center, there are shopping precincts around the city, with the strongest presence in East, North and Yongkang districts. 'Dream Mall' is a joint development project between Uni-President Corp. and Tainan Spinning Ltd. It was the largest shopping center in the city when it opened Feb 12, 2015 and the precinct will host the new headquarters of Tainan Spinning and a new five-star hotel. The precinct is in the designated East Tainan second CBD near the border of the East and Yongkang districts. Tainan Station is a major stop on the Taiwan Railways Administration (TRA) Western Line, with direct connections to Taipei, Kaohsiung, Taichung, Hsinchu, and Keelung. There are also local trains to reach closer destinations. Taiwan High Speed Rail's Tainan Station is located just outside the city center, in Gueiren District. The service is accessible to the city center via TRA Shalun Line and two THSR Shuttle Bus Lines. Using the High Speed Rail system passengers can reach Taipei in under ninety minutes. Original plan for system is muted due to the construction cost and the question of insufficient ridership. Upgrading current railway and buses are now considered as alternative citywide modern public transport options. Tainan has three major bus operators. They are Singing Bus Co., Shinan Buses and Kaohsiung Buses, operating in river north region, intercity routes and metropolitan routes respectively. In 2012, the city government called to restructure Singing Bus and Shinan Buses route to form a Tainan City Bus System. This new system, which set to start operation in 2013, has six main routes connecting the city and eight main interchanges. From the main routes 66 branch routes then spread out to service local communities. City government hope this new system will boost the public transports ridership and progress into metro-bus system in the future. A project to transform the railway in the city center into an underground is underway as part of the National wide "TRA Rapid Transit Systematization in the Metropolitan Areas Project". This project will help increase service frequency by eliminate potential disruption between road and rail traffic. Further to underground transformation, two new stations are planned to serve East district commuters. Together with the Shalun HSR link, this section of TRA corridor will become the backbone of the rail transit system in Tainan. National Highway Nos. 1 and 3 run close by and connect via local highways to the city itself.
