Few days ago I bought 29811 when removed from box and launched my locomotive on track everything was ok I mean drive, light work and sound was available as well. Today when I tryed play locomotive not working only lubrication sound from speaker can be heard and after that nothing happens. Address set on chip inside locomotive is 21 and this is original manufacturer setting, but when trying find address on central station, address is 15. Do you have any idea what is going on?
