Train drivers are set to stage more strikes in October as part of a long-running dispute over pay, the BBC is reporting.
Drivers at 12 train companies are expected to strike on 1 and 5 October.
Aslef, the train drivers' union, has not commented on the proposed industrial action out of respect ahead of Queen Elizabeth II's funeral.
A strike had been planned for 15 September, but was postponed following the announcement of the Queen's death.
Aslef will not be making any public statements or comments on further strike action until Tuesday.
But the managing director of rail operator LNER, David Horne, tweeted that the trade union Aslef had indeed notified it of strike action on Saturday 1 October and Wednesday 5 October.
Mr Horne said LNER had already suspended ticket sales for these dates and it would confirm as soon as possible which services will be running.
A rail industry source told the BBC that they found it "incredible" and "utterly disrespectful" that the Aslef leadership announced fresh strike action on Friday.
A series of large-scale rail strikes has already happened in recent months, causing disruption for millions, with unions wanting pay increases in line with the rising cost of living.
Rail bosses say they want to give workers a pay rise. But they and the government insist changes are needed to "modernise" the railway, end some outdated working practices and save money.
