NOT the USUAL Fahrenstock clip
Photo is Stock. Yours will be similar in ready to use condition.
Here is an American Flyer track terminal to hook up your transformer (power pack) to the two rail American Flyer track. These are also used for some accessories.
This is NOT the standard version with the Fahrernstock Clips. THIS ONE is the EZ style where you just have to put the wire in the middle of the clip. Often it just slides in--MUCH easier than the usual type.
This one is clean but does have some use and some oxidation and signs of use. Ready to use.
OPERATING TIP: USE TWO of these to spread power equally around the loop. Put them at opposite ends, and be sure the same wires are going to the same rails, and you are good to go! Especially helpful if you notice it slowing down on one end.
Photo is our Stock shot of one of this style. Yours will be similar in ready to use condition.
