London-Glasgow takes about 4h45m typically with about 7 stops. There's a train every hour between from 5am until about 6pm. Today the 5:30pm train is full, the 6:30 is £119 (€140) for a single ticket 2nd class. If you are more than 6'2" tall your knees will be wedged against the seat in front of you like on a budget airline, the ride quality on the train is too bumpy to be able to use a mouse or trackpad accurately with a laptop, you will struggle to select paragraphs of text. There is not really enough room to use a laptop anyway if you haven't booked a table. If you need to work, it will be necessary to upgrade to 1st class this costs £270 (€315). There is also a persistent fault with the toilets on this type of train that means sometimes there is a strong toilet smell.

Paris-Bordeaux takes 2h05m and is non-stop. If I go online now the next train is at 6:30pm and costs €60 2nd class. There is a non-stop train roughly every hour and there are also trains that stop 2-3 times that take about 3h but are a bit cheaper. The 2nd class seat is spacious your legs are about 5" from the seat in front and there is a table with enough space to comfortably use a laptop which has an individual socket and usb charging point per person. The ride quality is very smooth, you can easily use a laptop trackpad or mouse accurately enough to do CAD work, you wouldn't realise that you are travelling at 200mph. Edit: 1st class is available for €72 and did I mention that the train is double decker? it's just a lot cooler. Another edit: There are quite a few trains tomorrow with tickets for €29 and one train with a ticket for €12.50

Thanks for the reply. For what it's worth if you're ever in the US, Amtrak does offer very spacious seating and often enough you'll have your part of the row to yourself. Probably comparable to flying first class, I'd say.

Yes American trains are great, I've only used regional trains from New York but they were spacious and comfortable. Your Miami - Jacksonville pairing is interesting, I was thinking about it and I think the big difference between the US and the UK is that if you couldn't take the train in the UK all those people would be on the road and it would cause a traffic meltdown. Whereas in the US most people are going to either drive or fly between regional cities like that and the whole country is criss-crossed by freeways and flights that link cities together in a big mesh so you can drive or fly quite directly to your destination. I get the impression that most freeways outside of big cities have relatively predictable journey times in traffic. You can fly Glasgow/Edinburgh - London but it is also a busy route and there is no capacity in the London airports for more regional flights. Likewise pretty much all North-South car journeys in Britain are on two motorways which are very busy. The drive will currently take anywhere between 7-10+ hours depending on what time of day you travel.

Don't come across many Jacksonvillians around these parts. I use this train between Charleston and Jacksonville somewhat frequently and can second your experience with it.

That's not far off the same cost as to get to Glasgow from London, looking for tomorrow it's between £55 and £70. Significantly longer though for yourself, the train here is around 4 hours 45 mins (give or take). It's also generally close to on time, and we have delay repay for anything over 15 minutes.
