Kranji is located in Singapore Postal District 24.
The Kranji MRT Station serves the workers of the surrounding industrial estates such as Sungei Kadut. There was an initial plan for this station to serve a future KTM Railway Station which Singapore had proposed to be sited in its vicinity. That plan has since been shelved indefinitely due to disagreement with malaysia over the relocation of the KTM Railway Station from Tanjong Pagar.
The Kranji MRT Station is prone to sudden high influx of commuters, especially during racing days, as it is located near the Singapore Turf Club. To facilitate quite passenger processing, the station is installed with a high number of fare gates.
