Isle of Wight train services will be completely suspended over the weekend.
Island Line is shut for maintenance work.
A bus replacement service will run between Ryde Esplanade and Shanklin, while a mini-bus shuttle will be in place between Ryde Pier Head and Ryde Esplanade.
Island Line only reopened in November 2021, following a £26 million upgrade.
Since then the service has been blighted by staff shortages.
In September trains will be unable to serve Ryde Pier Head for at least three months. It's to finish what Network Rail are calling 'safety-critical maintenance' on Ryde Pier.
Network Rail said it wasn't possible to carry out works to Ryde Pier during its upgrade in September.
