 By developing the proposal further, Bulleid settled for a 0-6-0+0-6-0 design of bogied tank locomotive, which spread the weight more evenly over the rails and reduced the axle-loading.A series of initial ideas were presented to the Southern Railway management by Bulleid that incorporated double-ended running, giving the locomotive driver maximum visibility in either direction without a boiler or tender obscuring his view.The need for a turntable to turn the locomotive was therefore eliminated, although the initial designs were rejected by the operating department because of problems with welding technique.
