Tested and running very well, very, very smooth too. Note it only starts to noticeably move after speed step 9 on my gaugemaster prodigy express. With full dcc sound, lights etc. Beautiful locomotive, looks amazing! In very good condition, some loose pieces. Note: The sound is fully working etc, but it could likely use a better speaker – the ones nowadays are 10x better, and are only like 5GBP.
