Southern says it will be returning to its normal timetable tomorrow.
But it says some services may run with fewer carriages because trains will be out of their normal position.
It says: "We also expect there will be cancellations caused by the issues with train crew availability that we have been experiencing recently. Passengers are urged to check our website, external in the morning.”

Two hugely disruptive strikes, two different train companies, same issue.
The unions want to draw a line in the sand over something called Driver-only-operation or DOO.
It's where the driver is asked to close the doors at stations, instead of the on-board conductor (guard). Drivers have CCTV in the cabs to check people are clear of the doors, but the unions say it's still not safe and passengers will get hurt.
They’re also worried it's a Trojan horse policy to phase out train conductors in future, to save money and cut staff. The companies say they'll keep the conductors on board, they'll just be helping passengers instead.
The dispute is over the introduction of driver-only trains on which guards will no longer open and close doors
We've had DOO trains on Britain's railways for decades. The regulator (ORR) says it's happy they are safe and so does the Rail Safety and Standards Board but the unions don't want any more.
It's Scotrail and Southern this time around but this issue could flare up on any number of different lines in future.
People are talking about a "war" on the trains, between the unions on one side, the companies and the government on the other. Neither side wants to budge, and passengers are stuck in the middle.
