The transport secretary, Grant Shapps warned commuters on Monday that due to the rapid decline in people using trains, they could be shut down.
Shapps said if demand falls further then there is a risk trains being cancelled as there is “no point in running ghost trains.”
Last week railways saw a “big drop off” by up to 20% in passenger numbers, Shapps told the BBC’s Today show.
The MP told Radio 4, “A lot of them are in different situations because some, a couple now are effectively run by me, and some are companies.
“We’re working with them all to see what we need to do to sustain them.
“Obviously people still need to be able to travel to an extent.
“Some of that actually is about how many trains are put on the line at any one time.
“It’s quite clearly an exceptional international moment in time, we need to be flexible as a country to react to that.
“We’ll be driven, amongst other things, by the demand.
“There’s no point running ghost trains anymore than running ghost planes.
“Those are conversations, which I said, are ongoing.”
Speaking on flights Shapps said, “This week I’ll be having aviation summits with the airlines.
“I’ll be taking their collective thoughts on the economic and business response committee to work out which measures can and should be taken.
“They’re are clearly right at the forefront of this because global travel has come close to a halt in many areas.”
