A provider of many train services running between Sussex and London has apologised for planned serious disruption to travel on New Year's Eve.
Thameslink which provides some main-line services between Brighton and London, and between Three Bridges (Crawley) and London via Redhill, says a shortage of available train crew will bring problems for people planning to travel.
On Sunday 31 December, while there will be trains in the morning, there will be a significantly reduced service on Thameslink between Brighton and London (and north of London, too) in the afternoon and evening, and no Thameslink trains across the network at all overnight.
However, some alternative services are available.
Southern and Gatwick Express trains are not affected and Gatwick Airport will continue to be served.

Jenny Saunders, Customer Services Director, said:
"We’re very sorry that we’ve had to alter and reduce our service this weekend.
"As with train companies in other parts of the country, this is because of train crew shortages, with winter illnesses having a particular impact.
"We’re doing our best to limit the impact and spread services but, regrettably, we strongly advise passengers to check their journeys before setting out.
"On Sunday, the service will be particularly affected in the afternoon with no Thameslink trains overnight."
Already, the Thameslink website shows multiple London Bridge to Brighton services on New Year's Eve cancelled.
And the National Rail enquires website shows some services as running but, upon clicking "service updates", the reader is told "This service will not run".
Ticket acceptance is being arranged across other transport modes and routes, Thameslink staff said.
Passengers can claim for Delay Repay compensation if their journeys are delayed by 15 minutes or more.
