@Richie C. posted:Also, the LW transformer is a little quirky in that post A goes to the outer rail of your track (post 2 on a Lionel CTC lockon) and post U goes to the center rail (post 1 on the lockon),
Actually, it's not quirky, it's the norm for most transformers.
Only multiple throttle transformers use "U" as the common, outside rail connection.
