Thanks, guys. Good to know about the difference between wattages at which a transformer might be 'rated' and what it is actually capable of delivering. My question had less to do with the actual absolute values of the wattages, and more to do with whether the watts available from the KW could ALL go to one track (assuming the other 'channel' remained empty) - or if the total available watts from the KW would be split in half, irrespective of whether one or two trains were operating.
I had considered buying a ZW-L to run both loops on the new layout, but since the ZW-L delivers a chopped sine wave it won't be compatible with my BL-2 - and it seems like having a ZW-L to run just one loop would be overkill.
So my current thinking is to use the GW-180 to power one loop, and look for a reconditioned KW, or possibly a ZW (275 watt) unit - in order to get a smooth sine wave with which the BL-2 should be happy on the other loop.
Hi-Ho,
Sam
