Check out the first testrun with the Z-scale AZL Challenger equipped with a ESU LokSound micro V 3.5 decoder.
The decoder and the 2 speakers are placed in the tender. Some adjustment are needed; like light intensity and to turn off the coal showling in this oilfired monster. This first testrun was to see how the instrallation and the engine worked. I am satisfied and look forward to to use it in some real action on a bigger layout.
