After several years of storage and irregular use, L277 was sold to Southern Shorthaul Railroad in 2020 and was transferred to Cootamundra for reactivation work, which was completed in September 2020.

LZ3111 hauled three sister units as well as flatbed and well wagons to Avon Yard on 12 January that year before returning light engine back to Forrestfield.

Nearly a month prior to this, LZ3109 and LZ3114 were shipped by road to Progress Rail's workshops in Port Augusta for rebuilding and return to service.

As of 2 November 2024, LZ3119 (formerly L253) is located at Nowra under lease to the Manildra Group, where it will serve as the onsite shunt locomotive at their manufacturing plant in Bomaderry.
