Bachmann class 66 with Original GM recorded from Euro class 66 GM locos V3.5 loksound chip with Bass reflex 20mm x 40mm speaker fitted to the fuel tank facing the rail. Note there is no Interference from the body shell, which dramatically improves the sound quality from the speaker. I have added another two videos of the same Title showing the difference between the SWD (66111 EWS) and the Factory fitted SWD (66407 DRS) sounds.
