Centralen

Outside Central Station. (Say it with a Swedish accent and it's Swedish.) The tunnel under the street by Central Station. (Again, that's "sen-TRAHL stuh-HWOON".) Inside Central Station. (Not to be confused with T-Centralen, the connected-but-slightly-different subway stop.)

Swedish lesson of the day:
"tåg" = "train"
"buss" = "bus"
"tunnelbana" = "subway"
"Ett månadskort, tack." = "One month-long ticket to freedom of travel all over the greater Stockholm area, please."
