On the 100^th birthday of the locomotive itself, Marklin will be releasing the first HO Scale RTR Locomotive in over 30 years in both AC Sound and DCC Sound versions – the iconic Flying Scotsman.  This has been 3 years in the making and something that has been kept secret to ensure complete surprise when it was announced.

Model specifications

•  Controlled high-performance drive with a flywheel for a smooth ride
• Locomotive and tender largely made of metal for greater traction and high-quality appearance
• Factory-installed smoke unit with speed-dependent, dynamic smoke exhaust for a realistic effect
• Prototypical signaling on the front and tender for greater authenticity
• Adjustable close coupling with kinematics for better connection between the locomotive and tender
• Kinematics-guided close coupler with NEM pocket on the tender for easy coupling of all cars
• Buffer height on the locomotive and tender according to NEM standards for a prototypical display
• Brake hoses, imitation screw couplings, and closed cylinder covers for more detail on display or on large radii
• Maintenance-free warm white and red LEDs for long-lasting and energy-efficient lighting
• "World of operation" mfx+ decoder with extensive light and sound functions for more flexibility and variety during operation
• Particularly delicate metal construction with many separately applied details
• Cab and tender passageway lighting can be digitally controlled

Attention to detail is second to none, even the brass boiler bands are separately installed items. Finish and detail is nothing short of superb.

Marklin have also produced a video showcasing the development of the project:
