I'm sure this has been discussed, but what's your favorite station and why?

I think mine is the Haarlem station, with what might be called art nuveau stylings.

Probably least favorite is the Rome termini, only because I was a bit overwhelmed by it.

My favorite is Atocha in Madrid. It even has a little tropical rain forest in the middle of it. It is below street level, has been re-created from a huge old station, and is really exciting.

My favorite train station is Venezia Santa Lucia, because when I come out the front door I'm in . . . Venezia!

I'm also partial to Grand Central Terminal.

I like the one in Leipzig -- least favorite so far was probably the one in Wroclaw, Poland (felt like I was in another time/place, either a 3rd world country and/or 100 years ago). Leipzig is just very large and modern and attractive, easy to get around. The one in Wroclaw might be okay or expected in a small town, but that's a fairly large city.

I don't remember if it was Brussels main station or Bruge that seemed kind of heavy and brooding and reminded me of some kind of Italian fascist architecture.

Favorites-
Grand Central Station,NYC
St. Pancras,London
Strasbourg,France
Least favorite- Budapest

Well I like the answer about Venezia S.L. as a favorite. I think I vote for Napoli Centrale as least favorite - too many scammers lurking.

Same as Bitter - Haarlem, for much the same reasons. TAhe station in Antwerp is a strong contender too.

Venezia S.L is nothing special inside the station, but the panorama that hits you as you step out is jaw dropping, particulary for first time visitors.

Bitter, I think it must be Brussels - Bruges station is quite small.

Like ellenem, my favorite is my favorite because it is in my favorite place - any London station.

Most favorite: Chatapatri Shivaji, Mumbai

Least favorite: Limoges

I think the Frankfurt station is beautiful. It is 121 years old and they just finished cleaning it all up a year ago. Looks fabulous.

Least favorite is Brussels. Have been there a number of times and it is just so ugly and cold and dark. Like they don't have enough money for good lights or something.

Another vote for Leipzig as favourite railway station.

Prague's train stations are awful, especially Holesovice. Hlavni Nadrazi needs a thorough reconstruction (I think it's in progress) and then it might come out as a beautiful station. So far it is ugly and navigation is a pain.

I am with Ingo re Holesovice, love Atocha in Madrid

Köln (Cologne) is really gorgeous, esp. when you approach from eatern direction, over the Rhine, with that view of the cathedral.

There are many other impressive buildings: Leipzig, Hamburg, Frankfurt, Stuttgart, Dresden..

For modern train stations, Berlin and Frankfurt Flughafen.

Atocha, Madrid. Number one hands down. Beautiful.
Haarlem architecture is classic but the facilities are weak.
Antwerp has been redone and they retained the old main hall. Very nice.
St. Pancras is modern and very good.

Constanta is poor. Prague is horrible. Warsaw is worse. Give them time.

Dresden will probably be good when they finish the reconstruction. Maybe it's done. I haven't been there in 3 years. The new tram system is one of the best in Europe.

Amsterdam is also under reconstruction.

Another vote for Leipzig. A newer train station that I like a lot is the Avignon TGV station -- very modern, light and airy (and car rental is a breeze).

The worst train station I have ever been in is Prague -- it's the pits.

Re: Avignon
I wish that would have stayed at the old location just outside the walls. The buses are there I hope still ?

Another vote for Venezia S.L., again not for the station, but for the view when you step out...wow. My least favorite so far has to be Prague Holsevic, yuck!

As much as I don't like the city of Frankfurt, the train station is kind of cool.

Favorites: Helsinki, Milano Centrale, Grand Central. (And Orsay if former ones count).

Ugliest: Termini and NY Penn Station.
