You cannot reserve seats on Northern trains.
You can reserve seats on many other train operators' services and, if available, we will automatically try to reserve a seat free of charge.
If a seat cannot be reserved at the time of booking, it will be because of one of the following reasons:
- the train operator does not offer seat reservations (usually shorter routes)
- the train operator has not made seat reservations available
- the seats that are reservable are fully booked.
