I recently purchased the MTH 20-21583-1 B&O F-3 diesel and am not happy with the fog horn sounding horn that came with the engine.I looked on line and in 2016 MTH came out with 20-20605-1 B&O F-7 engine that has passenger station sounds.Does anyone have this engine and does it have the better sounding 5 chime sounding horn? Can this better sounding file uploaded to my engine without causing any operational problems.Both engines are Proto3 board locomotives.Any advice would be much appreciated.
