I have a Lionel ZW trainsformer which I operate with 2 135 and 2 180 watt power packs. If I measure the voltage at the track with five lighted passengenr cars and a Lionel ALCo PA A-A Diesel set on the track I get a reading of 14.5 volts with the transformer control set at maxium voltage. If I connect a Throtlepack 027 transformer to the track I get a 16.5 volt reading under the same circumstances.
I did this test because I find that the maxium speed of the PA A-A set is very slow (using TMCC).
Is the ZW ok and is the PA A-A diesel just that slow?
