I have traditional o gauge and one of the operating tracks is acting funny.  The operate button works fine but when I press uncouple it doesn't seem to work and it causes my lighting to dim on my layout (that is hooked up to the same accessory power post).   I have tried multiple controllers and switched and they all demonstrate the same behavior.  Now the train starting stalling on that spot as well.

The magnetic coil creates almost, but no quite, a dead short and pulls almost all the current available when the button is pushed. If powered directly, rather than using track power, it should be on it's own power supply.

 

That's why the instructions for the newer FasTrack uncouplers/control tracks specifically say not to use the 'Accessory' output on the CW-80. There's a good chance the current load would fry the output.

The reason for the caution on the CW-80 from this 2008 manual excerpt is because of the improper orientation/relationship of the "A" post(s) to the "B" post(s) on early transformers.  The first versions of the CW had "A" common to "B", and the "U" posts were variable.  The later versions with "U" posts common, with a "G" prefix date code, will work fine with the uncoupling sections wired for constant voltage from the accessory "B" post.  Program the accessory voltage to give satisfactory operation.

 

When the manual was printed, Lionel was aware of issue with the binding posts, but was in the midst of a fix for it, which resulted in the modified CW.

 

Continue to heed the warning about extended operation - the wiring for the Fastrack section heats up pretty fast in addition to the plastic on the track itself, and the new controllers, while looking like the old original 1938 style RCS versions, are not nearly as robust.

i’ve been running my 6-12020 uncoupler track off the CW 80 with no problems at all but that may be cause it is the “G” series no lights dim train does not change speed when I operate the uncoupler track and I have the accessory voltage set at almost 14 volts
