How to take the a rail journey from London to Perth in Scotland

This train service, which is also known as 'The Highland Chieftain', usually departs from London daily at noon (12:00).

Final Destination: Inverness

The train also calls at: Falkirk Grahamston and Stirling

The alternative overnight train:

This daytime train is scheduled to arrive in Perth at 18;00, but the overnight train is scheduled to arrive at the awkwardly early time of 05:40.
The overall journey time will be around 2hr 30mins longer, but you will be travelling on Europe's newest overnight train service.

Though note that the overnight train departs from Euston station and not from King's Cross station.

If you want to travel at the cheapest possible price, look for the 'Advance tickets', though the two key things worth knowing about booking and using 'Advance' tickets are:

(1) This type of ticket can't be refunded if you subsequently change your travel plans, or miss the train in circumstances not to do with a connecting train.

(2) A £10 admin fee will be payable if you want to exchange your ticket to a different departure to the same destination, to that which you selected when making your booking PLUS you will ALSO be charged any price difference with the new ticket you'll then have to purchase.

Also what is unusual about booking with LNER is that Advance tickets are now available online up to only 5 mins before departure.
They will have sold out sooner on the most popular trains, and the earlier you can book the cheaper they will be - but before buying walk-up Off Peak or Anytime tickets at a station, just prior to departure, it's worth checking on your phone to see whether Advance tickets are still available, before heading to the ticket counter or machines.

Travelling on Monday - Friday:

Tickets are usually available 12 weeks ahead of the travel date.

However, when you look up a journey you may see dates further ahead on the calendar, but you'll be informed that tickets aren't yet available for those dates.
On the LNER website you'll be prompted to sign up to a Ticket Alert service - if you will be using a PC, over on the right on the screen you'll be taken to, you'll see the furthest date ahead that tickets can be booked for.

Travelling on Saturday-Sunday

Tickets are usually available 12 weeks ahead of the travel date, but maintenance work on the route is periodically undertaken at weekends and if it is scheduled on your travel date, it can affect when tickets will be released for sale.

If you're looking up a journey less than 12 weeks ahead and tickets aren't available, it can be a good indication that works will be impacting on your travel date.
It can be worth checking this on the National Rail website - enter LNER as the operator.

Making an end-to-end journey will still be possible, so it can be worth signing up to LNER's ticket alert service, though you MAY ultimately have to take a substitution bus service for part of the trip.
It's the confirmation of these alternative travel arrangements which can hold up the release of the tickets for sale.

Reservations:

When you book an Advance ticket for a London to Aberdeen train journey, you will be automatically assigned a seat(s), but if you book the other types of ticket ahead, you can request a complimentary reservation - more info on this

Seat reservations aren't automatically included when booking Off Peak or Anytime tickets online, but you can add the complimentary reservation, once you've made choice of departure, either when booking or afterwards.
When booking walk-up tickets at a station ticket counter, if the Advance tickets aren't available for the next departure, confirm whether a seat reservation has been added to the booking of an Anytime or Off Peak ticket, in theory reservations will be available until around 5 mins pre-departure.

If you will be using a rail pass, including a Britrail or Eurail pass, you should be able to obtain a reservation, at no charge, from a ticket counter up until 5 mins before the departure; keep this in mind as it is not the norm when using rail passes in Britain.

Receiving Your Ticket(s) booked with LNER

The four options for receiving your ticket(s) are:

(1) You will receive a booking reference number on your order confirmation email and you can use this reference number to collect ticket(s) from a ticket machine.
Some stations will have dedicated ticket collection machines, but standard ticket machines will also have an option for collecting pre-booked tickets.

You will need to enter your reference number into the machine, so make sure you'll have easy access to it when you are using the machine.
You will also need to insert the specific credit or debit card you used when making the booking, so have that with you too.

Showing the email you have received to staff at the ticket gates won't get you on to the train, nor will this be valid if you can only show the email to the conductor when you are on the train.

If you forget to bring your ticket(s) with you to the station, but do have the card with you that you used when booking, you can use the machines to collect your ticket(s).

Take your time and take care that you have picked up all your ticket(s) and seat reservations.

(2) Print off the tickets you receive before heading to the station - the instructions for doing this are available here.

(3) Opt to pay an additional charge to have your tickets posted to you; not available when booking tickets from outside the UK.

(4) Mobile tickets - if you select this option when making a booking you will need to download the LNER Travel Buddy app so that you can 'Activate' your ticket.

The LNER website states that 'Advance' tickets will be automatically activated, but there's no suggestion on the LNER website that it will be OK to save the ticket(s) you will receive as a PDF to your mobile device.
So download the app to be sure that you can use a mobile ticket.

The potential to save by splitting tickets on Trainline

It can be worth looking up this journey on Trainline.

It can be possible to save money by using split ticketing, with the booking process being no more complicated than booking conventional tickets - find out more.

All trains also depart from: Watford Junction, Crewe and Preston (between London and Scotland these trains take a different route to the day trains).

This train is usually scheduled to arrive in Perth at the awkwardly early time of 05:40, while the daytime train is due into the city at 18:00.

Unusually for UK train tickets, you can book journeys on the Caledonian Sleeper up to twelve months ahead.
If you want a full choice of accommodation in the summer months or around holiday times, it's best to book at least a month in advance.

When making a journey by these Caledonian Sleeper trains, you can choose from three types of sleeping cabin, or you can opt to travel in reclining seats - If you want to travel in the reclining seats, you will in effect only be paying the journey costs.

In common with how tickets are sold to travel in sleeping cabins on other European night train services, there are two elements to the total cost of the sleeping cabin ticket price;
(1) the cost of making the journey, and
(2) the more expensive accommodation costs of travelling in the cabin.

On these Caledonian Sleeper trains the sleeping cabins  have a fixed price, regardless of how many people are using them, so how the total costs per traveller are calculated, is dependent on how the cabins will be occupied.

If you will be making an individual booking you will have sole occupancy of a Club Room or Classic Room - booking a Caledonian Double isn't an option for solo travellers.
The total cost per person is more expensive if you will be travelling individually, because if you travel solo you pay the full cost for the Club Room or Classic Room, plus a cost for making the journey.
But two people travelling together, can in effect split the cost of travelling in the Club rooms and Classic rooms between them, and the additional cost comes from having to purchase two journey tickets.

Paying a higher price for single occupancy of a sleeping cabin is the norm on European night trains, but this particular pricing methodology makes the sleeping cabins on a Caledonian Sleeper service, a comparatively expensive option for solo travellers.

Travelling as a family group:

The costs of adults and children travelling together will be calculated during the booking process - here is the relevant information.

Using Rail Passes:

If you will be using a valid rail pass you can travel in a reclining seat at no additional charge, but you must reserve a place prior to boarding, by calling the Guest Service Centre on 0330 060 0500.

If you want to travel in a bed in a Club Room sleeping cabin, you need to pay a 'Room only supplement' of £170 if you will be travelling solo, or £200 if two people will be travelling together.
If you want to travel in a Classic Room sleeping cabin, the supplement is £120 for solo travellers and £140 if two people are travelling together.

These 'Room only supplements' can be booked online.
