Services became disrupted again as soon as the lockdown caused by the COVID-19 pandemic took effect mid-March 2020.

In January 2022, the steel stairs was dismantled by PNR Crew along with DEL 5007 to be repurposed for the upcoming Inter-Provincial Commuter Train Service between San Pablo City in the province of Laguna and Lucena City in the province of Quezon.

Philippine National Railways inaugurated the Calamba-Lucena Line on October 6, 2022 in addition to the current San Pablo-Lucena route of Inter-Provincial Commuter Line which runs between the provinces of Laguna and Quezon.

The additional stops included in the extension are IRRI Flag stop, College, Los Baños, Masili, Pansol, and Calamba, which was also formerly served by the Metro South Commuter IRRI extension way back 2019.

A new Los Baños station will be built further south of IRRI station at barangay Putho-Tuntungin under the PNR South Long Haul project, a reconstruction of the existing narrow-gauge rail line to standard gauge.
