How long does it take to get from the Ouigo station at Tourcoing to the centre of Lille
Take the métro M2 at station Sebastopol (Tourcoing) in the direction St. Philibert (Lille)
Exit at the station Mairie De Lille (Lille)
Duration: 28 minutes
This is what was offered on the local transport web site. [original link]
It's in French but pretty easy to figure out.
Have a great trip.
If you prefer to visit the city you should take the tram from Tourcoing to Lille ..it is much better and you would visit the city. Get of at the last station.
Thank you both
