I'm feeling like a total dunce here. I've been working on the logistics of visiting the Dalí Museum in Figueres. I have all the pieces of the puzzle in place except for getting from the Hotel Granvia to Barcelona Sants and the reverse.
I like to use Google Maps to find the best (for me) ways to get around using public transportation and my feet. Google Maps is telling me that the MD/RExpress options are the fastest. The little symbol looks like it's rail of some sort.
I tried to find out what that means. Above ground? Below ground? Train? Metro? Tram? I dug around on the websites for the different types and failed. One place I looked had something about M in tiny print, but it didn't make any sense to me.
The obvious question is what is MD/RExpress?
