CrossCounty passengers are being asked to reserve their seat before travelling to ensure trains are not overcrowded.
The request to book a seat in advance is to ensure that social distancing measures can be adhered to on trains and reduce coronavirus transmission.
Travellers have already been asked to stay apart and to sit at least one row away from other passengers.
Now, with numbers set to increase as the lockdown begins to ease, all passengers are now being asked to reserve a seat.
Seats can be reserved when purchasing a ticket in advance.
For on the day travel or people with season tickets, bookings can be made through CrossCountry’s social media pages or via their Customer Relations teams.
Due to the fact that only around one-quarter of seats can be used to maintain social distancing, specific seat numbers will not be provided.
Instead, passengers can use any available seat in standard or first class depending on their choice of ticket.
However, when all spaces have been booked, train travellers are asked to use an alternative service as they will be unable to buy a ticket without a reservation.
Speaking on the changes, CrossCountry’s managing director, Tom Joyner, said: “As more people resume travelling it’s important we maintain a safe environment for their journeys.
"With fewer seats than normally available, we are asking people to book a seat so we can manage the number of people on each train and help everyone keep a safe distance from others.”
