It should be possible to find a map of the longdistance rail routes - I know there's one for the TGV and the Eurostar.
ThanksTa da

There's a map link on that page which shows it. I went to Madrid by train earlier this year and wanted to know the same thing

If you can afford it, I'd really recommend having a meal in the restaurant car. It's properly like a posh meal in a really nice restaurant, but not ridiculously expensive. And you get to watch the world go by as you eat. We met a few really interesting people in the bar and restaurant (including an American guy having a midlife crisis who'd never been to Europe but got divorced and sold his house to go travelling 
). ). But we've done loads as we both hate planes through France, Italy, Spain, Turkey, Serbia, Croatia etc etc . Tbf anything is better than sleepers through Eastern Europe where you get woken up by 3am by stroppy border guards shining a torch in your face wanting to see your passport 
Bulgaria totally needs to sort out it's customer service skills
We've already decided we are eating in the restaurant car
The journey out is really a part of the short holiday and I'm planning treats from as soon as we get on the first of the trains from home.
Unfortunately we can't afford the train both ways so it's a cheapo flight back at the end of it.
We both hate flying, so tend to do a "proper" holiday in Europe every 2-3 years cos the cost is so much more. I reckon we could have gone to New York for a week for the same price that we paid to get the train to Malaga and back for 10 days earlier this year
