Rosecroft Raceway, which had been shuttered since last year, will re-open for simulcast races on Thursday.
Under a new ownership, the Prince George's County harness track will open seven days a week to accept bets on harness and quarterhorse races from across the country.
The track will resume live racing on Oct. 21 after a nearly three-year absence.
Casino operator Penn National Gaming bought Rosecroft for $11 million earlier this year in a bankruptcy auction.
An earlier version of this article misstated the amount of money for which Rosecroft sold at auction. The Baltimore Sun regrets the error.
