To all,
I miswrote when I referred to the poor performance with a 90 Watt transformer. I looked again this morning under the Christmas Tree, and see that it is a large 175 Watt transformer running the Santa Fe diesel on 027 gauge track. The engine runs fine, although reversing of the A-B-A + 3 passenger cars is pretty slow!
However, the 175 Watt Transformer really powers my Steam engines and Milwaukee diesel with a full set of freight cars very well!!
