On weekends when there is a shutdown between Sydney and Wollongong, Steel train PW4 splits at Moss Vale, with PW4 continuing to Sydney and 2920 forming to run to Port Kembla.
The lead two units detach and prepare to stable next to NR31. The two lead units are planned for 2920 (the rear portion of the train).
NR31 has suffered a radio failure, and as such, ended up pulling the Sydney portion of PW4 into the refuge siding (and was subsequently hauled by an 81 to Sydney).
