ransformers were issued by Lionel thoughout the Post War period. From 25 Watts to 275 Watts, a Lionel transformer could be found for every power requirment from simple circles of track to extensive railroads. The larger transformers could operate up to four trains independently. The higher powered units would not meet todays’ safety standards as issued by Underwriters Laboratories.

Early issues used a Bakelite case while later releases had a case made out of plastic. All of the transformers that have more than 90 Watts are in great demand today as more collectors are operating retro-layouts.
