I have made the following discovery regarding smoke production in my Lionchief+ B&O locomotive.
After its repair, it did produce smoke but a bit meager; but, that was using the supplied wall power supply.
Today, I connected its track to the ZW-L and ran it.
Big differences:
It used to take about 4 minutes to get some whisps of smoke; but now, less than a minute.
When I throttled up, smoke production decreased and you only got some smoke when at a slow speed; but now, she produces nice smoke at moderate speed.
So the ZW-L is supplying the necessary amperage for the smoke unit.
