Despite tomorrow's rail strike being suspended, many trains will not run.
Govia Thameslink Railway, in charge of Thameslink, Southern and other lines which run from Brighton station, has confirmed that many smaller coastal lines will not run tomorrow.
"Our advice is as it was. We recommend that people do not travel by rail tomorrow," said a spokeswoman for GTR.
The company said that main routes from Brighton would go ahead, but it would be unable to reinstate services such as Brighton to Lewes due to short notice.
"We will work hard to see what we can do for Monday and Wednesday's cancelled strikes, but for tomorrow there is not enough notice," said the spokeswoman.
