Reply to "Lionel KW transformer - is wattage (per track) dependent on number of tracks?"

Note that the KW doesn't actually deliver anything close to 190 watts.  Postwar transformer are rated on input power, considering an efficiency of maybe 70-80%, the actual output power is around 140 watts.

Modern transformers like the Lionel ZW-L or the PowerHouse 180 are rated on output power.
