The Green Corridor of Singapore was previously the KTM Railway Track now converted for public use. The track runs north to south of Singapore from Woodlands to Tanjong Pagar. Due to its strategic spinal connection, Public Utilities Board (PUB) has been laying huge water pipes under this track to supply for future needs in newly developed parts of the Marina Bay district. Sivasothi (@otterman) and I explore the pockets of tracks open for public to use, while works are ongoing for the next few years.
