No trains are running across the county today amid the latest round of rail strikes.
Members of Aslef at Southern, Thameslink and Gatwick Express, who provide rail services across Sussex, will walk out for the day in a dispute over pay.
The dispute is now the longest ever in the rail industry.
There is a glimmer of hope that negotiations will start in a bid to resolve the row after the Rail Delivery Group (RDG) invited Aslef to talks about exploring any common ground which could break the deadlock.
No formal talks between the operators and the union have been held for a year and for longer involving a transport minister.
Business groups have warned of the impact on the economy of the strikes, especially for hospitality firms.
Muniya Barua, deputy chief executive at BusinessLDN, said: “Yet another round of industrial action across the rail network will cause disruption for businesses and commuters up and down the country.
“Amid weak economic growth, and as we head into a summer trading period which is crucial for retail, leisure and hospitality firms, we urge all parties to work together to resolve these long-running talks and keep the city moving. The impact of these walkouts will be felt even more acutely by many owing to a shorter working week.”
Strikes will be held on Wednesday and Thursday at different operators, while drivers are also banning overtime until Saturday which is also causing disruption.
Passengers are being urged to check before attempting to travel by train this week.
Aslef said its members have not had a pay rise for five years and has accused the Government of “giving up” trying to resolve the dispute.
A spokesman for the RDG said: “The rail industry is working hard to keep trains running but it is likely that services on some lines will be affected on the evening before and morning after each strike between May 7 and May 9 because many trains will not be in the right depots to start services the following day.
“We can only apologise to our customers for this wholly unnecessary strike action called by the Aslef leadership which will sadly disrupt journeys once again."
