Core Viewpoint - The opening of Metro Line 18 and two other lines has significantly improved commuting convenience for residents along the routes, with particular attention on the interchange between Line 13 and Line 18 at Longze West Station [1][5]. Group 1: Line Operations and Interchange - Residents are concerned about the interchange between Line 13 and Line 18 at Longze West Station, questioning whether Line 13 will still stop there and when the interchange will be operational [1][3]. - The relevant authorities confirmed that the expansion of Line 13 will allow for a direct interchange with Line 18 at Longze West Station, although there is currently no notification regarding the addition of virtual transfers at this station [2][5]. - The original plan involved splitting Line 13 into two lines (13A and 13B), with the interchange at Longze West Station, which has raised questions among residents about the current operational status [3][5]. Group 2: Construction and Future Plans - There are suggestions from residents to expedite the construction of Line 13 at Longze West Station to enable early interchange; however, the authorities noted that the complexity of the project and the nature of linear transportation systems prevent independent opening of stations [5][6]. - The construction of Line 13 is a unique case due to the new station at Longze West, which is not an existing station on Line 13, making it impossible to open the interchange independently [5][6].
