Would it be a good idea to make a reservation?

• You are travelling in Britain...and decide to take the train.
• You are asking for train information.
• Sometimes, on some routes, at certain times of the day, the trains are packed (completely full.)
• Making a reservation is sometimes a good idea to ensure you get a seat.
• It is a seat reservation.
• It's pretty miserable (and annoying) to pay £40 for a train ticket and then have to stand up for 3 hours.
• It's free to reserve a seat, but you may need to book the ticket in advance.
• You have to reserve the ticket for each section of the journey. So, if you have to change trains twice on a journey, then that means you'll have to make reservations on three trains.
