Grimrail Depot is a 5-man dungeon in Gorgrond introduced with Warlords of Draenor. If you’ve ever wanted to enjoy the sights of Draenor by train, then this isn’t the ride for you. If you want fast paced action on a moving train, then we’ve got you covered. The Grimrail Depot is a level 100 dungeon and a vital hub in the Iron Horde war machine. Allowing for the transport of troops and materials produced in the Blackrock Foundry to the front lines of the war being waged across Draenor, the Depot’s namesake is the Grimrail itself. This massive train can bear entire battalions of troops and artillery. Fitted with a massive railgun powerful enough to shatter the shield protecting Shattrath, the train is about to depart. Do you have your boarding pass? It’s going to be a heck of a ride.
