You can buy TEC bus tickets here too. We bought train tickets to Charleroi (6.4€ with discount) and bus tickets to airport (6€, no discount). Both were punctual.
Built in the late twenties this station was a modernistic pearl of pure international style. It still looks gorgeous in some aspects but you have to have an eye for detail.
Exit out of the centrum side. This is the nicer side of town, the other side has a peep show and a bit raunchier... Well may not be bad if you're into those kind of things.
Not really the cutest of all stations, although the view from platform 1 is OK. It's not as unsafe as people claim, but to be sure, try to avoid the bathrooms!
Direction Bourse / Beurs or Grande Place / Grote Markt take tramline 3 to Churchill / or line 4 to Stalle, both on level -2. Finance Tower take bus 351 or 358 on level -1.
Looks like a rather old train station they desperately try to make better but always failed. Sad. Intrigued by the former museum there though. Would love to get a closer look.
