Therefore, an agreement was struck between Singapore and Malaysia for the extension of a railroad line from the Bukit Timah railway station on the main KTM-operated railroad line between Malaysia and the Tanjong Pagar railway station near the city-district of Singapore towards the newly established industrial estate and Jurong Port.

Despite the significant investment in the establishment of the "Jurong Line" with its relevant infrastructure and the general notion amongst the population at large that it would play an important role in serving Jurong's industrial estate and the port through freight-based railroad transportation, there was not much true worth in the "Jurong Line" (only a few industrial operators based in the surrounding area made use of the railway line for its original (and sole) purpose of transporting freight; these included the Sugar Industries of Singapore (SIS) Ltd., Asia Cement (Malaysia) Ltd., the Pan Malaysian Cement Works Ltd. and Exxon Mobil Asia Pacific Pte Ltd).

In 2010, some remains of the tracks of the "Jurong Line" were dismantled by the KTM to replace the damaged rails in Bukit Timah railway station where a significant derailment accident occurred.

The same year saw the Jurong station's destination signboard removed and lost and most of the remaining tracks were dismantled by the Singapore Land Authority (SLA) between August and September 2011 after the Tanjong Pagar railway station closed on 1 July that year.

Only the old bridges atop the Ulu Pandan River, above a road at Sunset Way, beside Jalan Ahmad Ibrahim, before and after the Shipyard Road railroad crossing and above a river at Tanjong Kling along with tunnel crossings through Clementi (between an estate at Sunset Way and Maju Camp), the Teban Flyover and a major roundabout under the Jurong Island Bridge still exist.
