Next loco in this series is WDG 3B. It was a experiment didn’t work out because there is no record of any locomotives of this class today and no confirmed sightings of any of WDG3Bs except for a 2004 account by a railfan reporting a Gooty WDG3B #14796 (pictured here). This loco is now a WDG3A with SWR KJM.
