Line 2 
Construction on Line 2 began on December 25, 2009. From Suzhou High-Speed Rail Station (other sources refer to it as "Suzhou North Railway Station") it will run southward to Yingchunnanlu (迎春南路) at the South Outer Ring Road in Wuzhong Economic Development Zone. According to updated traffic maps of Suzhou city, at least a part of line 2 will be opened in July 2013. This will be the part from Suzhou Railway Station (苏州火车站 / Suzhou Huochezhan) to Guangjinan Lu (广济南路 / Guangjinanlu). The rational being that in this way Line 1 will finally be connected to the railway station. Line 2 will be 27 km long and have 22 stations.
Line 3 
The main line of Line 3 is planned to run from Xinquchengtie station next to Suzhou New District Railway Station in the northwest, via Wuzhong District in south Suzhou to Weiting in the east, with a total of 31 stations. A branch line is also planned to serve Suzhou New District better. Unlike the main line, the branch line will head westwards from Huashan Road station onwards. According to current plans construction will start in 2012, opening is scheduled for late 2015 or 2016. At the planned interchange stations with Line 1 and Line 2, which are currently under construction, platforms for Line 3 will already be prepared. Furthermore on some streets along the main line of Line 3 in Suzhou New District some simple preparation works are conducted. This might indicate an intention for an earlier construction start.
Line 4 
Line 4 will start in the north of Suzhou, west of Line 2. It will travel from Wanggengshang station via Wangshan road in the southwest of Suzhou. After reaching Suzhou railway station, it will almost exactly follow Renmin road and Dongwubei road to the south and at Shihu road turn southwest towards its (planned) end destination. Line 4 is planned to have 22 stations. According to current plans construction will start in 2012, while opening is scheduled for late 2015 or 2016.. At the planned interchange stations with Line 1 and Line 2 which are currently under construction, platforms for Line 4 will already be prepared.
Lines under planning 
Extension of Line 2 
According to network maps published on the website of the future operator, Line 2 will in future be extended into both directions behind its currently planned terminal stops. Behind Beijing–Shanghai High-Speed Railway Station (苏州高铁站 / Suzhou Gaotie Zhan - at the Suzhou North Railway Station) an extension is planned into north-eastern direction. Behind the currently planned terminal stop Yingchunnanlu (迎春南路) an extension in almost straight eastward direction is planned. 
Alteration of the south part of Line 4 
In addition to the extension of Line 2, a change of line management of Line 4 seems to be planned in the medium term. According to the line planning information on the operator's website, in future the layout of Line 4 will be changed. At that time it will not turn west after Shihulu (石湖路) station but instead will be extended southwards to Wujiang City and then turn sharply east, in order to better connect this city with its currently about 1.5 million people to Suzhou. The original part of Line 4 after Shihulu (石湖路) station (via Chenghuxilu (澄湖西路) station to Wangshanlu (旺山路) station) will be separated and operated as another Line.
Line 8 
According to those plans the old part of Line 4 between Shihulu (石湖路) station and Wangshanlu (旺山路) station will be operated as Line 8. The line planning maps already carry signs of a planned south western extension of this line.
Other lines 
The allocation of a number 8 suggests that there is an intention to build at least eight lines in total. Nevertheless, up to now there are no reliable information about layouts for Lines 5, 6 and 7.
