This locomotive has been wired with a dcc sound ready plug. The decoder that was installed has melted the plastic coating when the original Rivorossi motor burnt out. It seems to run the new can motor but there is no sound, so ive taken it out for a "DC" plug. The decoder will be included. I've decided to upgrade to a brass engine anyways so this one gets the boot! Runs okay but it's noisy with the retrofit
