Heljan 25/3 fitted with a Zimo sound decoder test

Hi there think it would be more realistic if the fan on the 25 was spinning as it went into shutdown, still sounds good though!.🙂👍.

Great sound!! Is this OO gauge or O

[@jintysvideos5015]

Thanks. This is all O gauge on my channel. Zimo decoder with Paul Chetter project through two bass reflex speakers.
