Train operator Connex says passengers in Sussex should have no problems reaching their destinations over Christmas, despite cuts in services.
Unlike other rail operators in the country, the company is not taking advance bookings on services during the festive period.
A Connex spokesman said: "Judging from past experience, we believe we are running sufficient services for the number of people expected to be travelling.
"We can't predict the weather but the majority of speed restrictions have been lifted."
Rail passengers faced more delays this week after a landslide at Merstham in Surrey and flooding in the Patcham Tunnel, between Hassocks and Preston Park.
