Long-standing suggestions have included replacing the class 483 trains with newer London Transport stock which has also been retired, such as the 1972 stock and 1967 stock. A plan to reinstate the passing loop at Brading was suggested in 2007–8, because Network Rail believed the line's signalling system needed replacing imminently and thought this could happen during the 2012 London Olympics. In September 2019 it was confirmed that a passing loop will be installed alongside other works on track and the introduction of replacement rolling stock, allowing trains to run at even 30-minute intervals rather than a 20-minute then 40-minute gap. It is hoped that these improvements will encourage greater use.
