help with trains from London to Edinburgh

What kind of thoughts are you expecting?

Nice for you, I hope you have a great vacation!

you should, it's a great way to travel. And the internet happens to chock full of info on how to do it.

First, read Rick's guidebook. Second, check with the Man in Seat 61.

LNER is the train operating company that covers the east coast main line and the route between London and Edinburgh.

It's way too far out to buy tickets, but you can set up a ticket alert to let you know when tickets are available on the LNER site. Advance tickets are usually released 12 weeks prior to date of travel. Though LNER does at times release advance tickets a couple/few weeks earlier than 12.

Lumo also operates some trains between London and Edinburgh as well. https://www.lumo.co.uk/

Easy to do. About 5 hour journey from Kings Cross station to Edinburgh Waverly station.

You don’t need a guidebook - just look on the LNER website about 10 weeks out for booking. Let’s hope the train strikes have ended by then.

Thoughts about what? Multi trains everyday. Lots of people do it. It is fairly cheap if purchased early.

Just hope that the strikes are over by then !

Jennifer is of course right. That 10 weeks out is an ideal time to check ticket prices. Which is one of the oddities of LNER in that they release tickets early -- right now for example tickets are available for travel 14 weeks 2 days out from today. Sometimes even earlier, and these early releases can be dirt cheap tickets. So do sign up for a ticket alert to be notified when tickets are actually available for your desired day of travel.

Also if you sign up for LNER's perks program you'll get a £5 credit that can be applied to your ticket purchase.

We took that train last June (to Fort Williams, not to Edinburgh). I'll do it again if I get the chance; I'm not sure of my wife though.

wondering about the post just above by rog - what relevance does it have to the question? What point are you making?

It's just nonsense spam. Reported (along with all his other equally inappropriate spam). Gone by Monday at 10 am PST.

I took the train last January to Edinburgh and back from London. I took the sleeper on the way back, which i probably wouldn't do again. It is such a short trip that you barely have time to sleep. Particularly if you plan on eating on the train. Plus, I had to stay up so late in Edinburgh without a hotel waiting for the train with my luggage. Check out Seat61's pages and videos. I found them very helpful. Sit on the East side of the train (right going up, left going back) for the most dramatic views.

I had a second-class BritRail Pass when I boarded the London-Edinburgh train at Ely after enjoying "Sunday roast" with some friends.

The display at the station indicated that all the second-class cars were SRO, and I didn't relish the thought of standing all the way to Durham (my destination for the evening) with my bad knees, so I asked about first class. It turned out that I could just take a seat in first class and pay a surcharge on my second-class BritRail Pass when the conductor came by.

I braced myself for a hefty charge on my credit card, but it turned out to be only £25, and it was well worth it. Free beverages and snacks were included, and while I didn't need any food, I did appreciate the excellent coffee.

It was midweek when I proceeded to Edinburgh, and second class was uncrowded. so I didn't bother to upgrade, but it's worth knowing that the option is available to second class BritRail Pass holders.

Book as early as you possibly can. Schedules don't usually come out any earlier than 90 days in advance though. But the fares can vary by A LOT if you don't.

My son and I took the trip this past September.

It was very enjoyable with lots of pretty scenes and I believe it was in the neighborhood of 5 hours. I believe we booked our seats facing each other with a table in between, which was also nice.

We happened to plan it and had purchased tickets on a day that was later announced as a strike date, but we were reprieved by the observance of the Queen's passing, which resulted in cancellation of strikes. I would just keep a backup plan in mind and, having scrambled for a plan myself, I suggest the plan be an idea of last minute accommodations as opposed to an attempt to get alternate transportation. You could fly, but if there is a strike, it may be a little more complicated to reach the airport and a bit more busy there as well.

I suggest arriving at the train station early as they are busy and large and no refunds or replacements are given for missing your trip. It's not for everyone, but I quite enjoy a bustling train station and a nice train trip.

The previous poster is right on. It will be far more economical to book flights a couple weeks out if you wait til the last minute to book train tickets.
