Train travel

Hi everyone!

Does anyone have suggestions for how to research prices for train travel?  My husband uses the Renfe website, but it won't let you search out more than a few weeks and we like to plan months in advance.  We took the train last summer around Spain and it was fantastic, so we'd like to do more traveling this way.

Thanks for any tips!

My wife says seat61 is cracking. I've never tried it myself.
