Engineering works will affect Island Line services this weekend (Saturday 18 and Sunday 19 May).
Trains will be suspended between 11pm on Saturday and 9am on Sunday.
Operator South Western Railway says it means there will be no early trains between Shanklin and Ryde St Johns on Sunday morning.
That day, the first services will run at 0907 from Ryde Pier Head and 0938 from Shanklin.
If you have to catch the 0747, 0847 and 0947 catamarans from Ryde Pier Head, you are warned to make alternative arrangements.
