Rail commuters have faced further travel disruption after the weather forced First Capital Connect to run a reduced service into London.
The firm said it had been running a reduced timetable on the Thameslink Bedford to Brighton route due to ice damage to 17 of its trains.
Last week's snow damaged motors on the trains, which First Capital Connect said it was working to repair.
The reduced timetable will operate on the Thameslink on Tuesday as well.
A spokesman said: "The recent cold weather has had a significant impact on our Thameslink route train fleet causing damage to key components meaning we have operated a reduced service.
"We have engineers working around the clock to repair the trains which are unavailable and we will be adding additional services in this evening's peak.
"Customers are advised to check our website before they travel for tonight and tomorrow's service."
