YES!!!
The train goes via Düsseldorf-Flughafen, Duisburg, Mülheim ( near Oberhausen ), Essen, Bochum to Dortmund.
When you arrive in Dortmund, you leave the station and visit ( 5-10 min. to march, you can ask everbody to show you the way ) "Alter Markt, Hansaplatz" ( Weihnachtsmarkt with the largest christmas-tree of the world ). Afterwards you enter - after a few beers or "Glühwein" - the underground at "Stadtgarten" or "Reinoldikirche" with the destination "Stadion" or "Westfalenhallen".
Who likes, marches from the city along "Hohe Strasse" directly to the stadium ( about 25 min., if you do not visit the many pubs along the way to the stadium, by the way: guests are welcome! )
I was very pleased by the atmosphere in Manchester and I think you should be too in Dortmund.
Thanks, looking forward to it
