the line between East Williston and Mineola was electrified, with the remainder of the branch expected to be electrified soon after. However, the remainder of the work was not completed; as a result, the branch is served by diesel powered-locomotive trains, though in the past one AM peak train that originated at East Williston and ended at Penn Station utilized electric multiple units. In 2009, the LIRR replaced the bridge over West Shore Road between Locust Valley and Oyster Bay Stations. In the late 2010s, the LIRR replaced and raised the bridge over Buckram Road between Locust Valley and Oyster Bay Stations. In April 2021, then-President Phillip Eng announced that the LIRR entered into an agreement with Alstom to test battery-powered train cars along the Oyster Bay Branch. The branch was chosen due to the short 13-mile trip between East Williston and Oyster Bay. The project had the potential to improve service along the branch and across the LIRR's remaining diesel territory. However, after spending $850,000 on the project, in July 2022 the LIRR announced that retrofitting existing trains with the technology was proven to be unfeasible, but the technology could be added to future train cars. Environmental groups continue to pressure the state to include LIRR electrification in their plan to become carbon neutral by 2050.
