Transport union, RMT union, have announced the suspension of planned strike action on Merseyrail, Northern rail and Southern rail, following the bombing at a music concert in Manchester.
The 24-hour strike was due to take place on Tuesday, 30 May.
Rail workers in Carlisle participated in a Union "day of action" between 7am and 9am this morning.
They are joining staff across the north in a campaign to have a publicly owned system in the region.
The RMT Union claims jobs, services, and safety are at risk if franchises are awarded to companies outside the UK.
In the wake of the cancelled franchise for the West Coast Main Line, one leading rail union claims almost half of the existing franchises are now receiving public bailouts.
The RMT claim 8 of the 19 franchises are being subsidised by the taxpayer and are calling for the full renationalisation of the railways.
The union also claims that revenue support payments made to train companies has increased from £290 million a year to more than £450 million.
The Department for Transport has suspended 3 members of staff over flaws in the franchise bidding process for the West Coast Main Line. A full investigation is now taking place and department officials are declining to make any other comments.
