Interestingly, and very relevant to this thread, this afternoon I went to a Garden Open Day hosted by our local (Essex) G Scale Society area co-ordinator - and one of the locos he had was an early "growler" tram EXACTLY like Henri's new acquisition, including the gold embossed lettering. He did say that he hardly ever ran it, but we put it on the track and although it WAS definitely noisier than either a clamshell or modern sandwich gearbox, it wasn't anything like as unpleasant and screamy to the ears as the one in the video that is attached to one of the other recent threads on "growler" locos..... so maybe they are not all as bad as they are made out to be....?
