Even if noted as running well, it is always advisable to do a proper clean and lube before extensive running as dust, old lube, aged rubber, etc all need attention. Specific comments for this item follow below. Tested and running very well, very, very smooth too. With full dcc sound, lights etc. Beautiful locomotive, looks amazing! In very good condition, very little use. It has an MRC decoder and tested out with gaugemaster and ztc DCC controllers, all functions are working. Note: The sound is fully working but it could likely use a better speaker – the ones nowadays are 10x better, and around 5-10 GBP. You will get what you see, if you don’t see it then it isn’t included. If not sure, please ask me. In particular, if I don’t show or state there is a box, or battery, etc then there isn’t. Please don’t assume there is.
