my name is roger because of a stroke I am not able to drive so my wife and me are planning to do 4/5 countries by train with me in a wheelchair from Nottingham any ideas on tickets and trains or anything else welcome thanks roger

Welcome to Fodors -- there is just too much info out there to be able to give you useful advice without knowing which countries

But the bible re rail travel is https://www.seat61.com

Start there . . .

Even years ago all main train stations had lifts if needed to cross tracks, etc and special areas for chairs on trains. But I would email the national railway of each country and ask them about this. Stations have wheel chair services where needed - like getting n trains but may need to be told about that before the train.

Yet I've seen lots of chairs on trains all over - usually a designated empty spot and adjoining seat sometimes near entrance to trains. I have not traveled by train for seven years but even then this was all true - so it's very possible but you may have to go thru some hoops to use services offered.

thanks janis for alerting me of my mistake!

Pal -- they are traveling on the Continent . . . UK franchisees and nationalrail aren't all that relevant once they get to the Channel . . .

Or did you read 'countries' as 'counties"? . . .

Oh -- jeeze -- now editing to remove mistakes . . .

That wasn't an 'edit' it was a complete re-write

Of course because I did sloppily mistake OP that they were going around U.K. I thanked you for pointing out to me - thus a re-write. Now what possibly is wrong with that?

The Guardian travel section recently had a series of articles on train travel in Europe. You may enjoy reading them to get some ideas.
You may have to book wheelchair assistance at some stations. Once you have an idea of which countries you would like to visit you can visit their national railway site for further information.

In Britain you have a few dozen different rail franchises - independent rail systems so go to www.nationalrail.co.uk and see which franchises run trains you want and email the franchise for relevant info. On the Continent yes they all have national rail systems you can contact.

Before sending out dozens of e-mails, I'd check the websites of the respective railway companies for information on accessible rail travel.
Also on the "Continent", it's not uncommon that there is more than just the one or incumbant national railway company.
Once you know where you want to go, it may be easier to offer useful advice re. wheelchair travel by rail in the 4/5 countries you plan to visit.

Get a lightweight, fold-able transport chair like the one below, soooo much easier to store on a train. The Super Light Folding Transport Chair with Carry Bag by Drive Medical is really good
