The company say the coronavirus outbreak has made keeping a service going 'unsustainable'.
Train operator Grand Central is suspending all services between Bradford Interchange and London for two months from the end of today (Friday 3rd April).
The company had kept a reduced timetable going for the past two weeks, but say continuing this is now 'unsustainable'.
Grand Central's trains also call at Low Moor, Halifax, Brighouse and Mirfield, and normally run four times a day in each direction to and from London King's Cross.
Anyone who has already purchased a ticket for the next two months can claim a full refund from wherever they bought it.
Grand Central have released this statement:
"Over the past two weeks Grand Central has operated a rail service, under a reduced timetable, in order to keep key-workers moving at a time of crisis. As an Open Access rail operator, this came with all the costs of running a train service, while bringing in no revenue to our business and with no Government support. This situation is unsustainable and, following several days of discussion with the Department for Transport, Grand Central has decided to suspend all its services, for an initial two months, from the end of service on Friday 3rd April.
"Customers who have a ticket to travel with Grand Central over the next two months can claim a full refund from the place they bought their ticket.
"Customers who absolutely need to travel can use their Grand Central ticket to travel on other train companies’ services.The Grand Central website and app will remain available, and show live train running information for all operators’ services and can be used to buy tickets for any train company’s revised timetable services."
