When using the European train network you'll find each country has their own set of trains. Some are better than others, but for the most part they're all pretty good. Some have sleeper cars, some have seat that recline, or seats that pullout. Some even have tv's!
You'll also find that some trains move painfully slow, stopping at each little town while others fly by at speeds of over 300 KM/H taking you half way across a country in a matter of a few hours.
Soon, I'll add a list of each of these trains, and explain a little bit about them.
