I own one Legacy base/remote. I have a layout at home and I also have a fast track loop at my school. I have found that playing with trains is a powerful motivator for my students! Plus, selfishly, I get the biggest kick watching them play! (I am continually amazed at how quickly they figure out how to use the legacy remote.) So, when a kiddo earns it via a contract or when a classroom does something great I let them run an engine around the loop. I bring my legacy base to work. I want a second chord because to plug it into the wall I have to crawl under the table. So, I am basically being lazy and just want to plug the base into the pigtailed chord. I could use an extension chord, but then I still have to unplug it from my home layout. At home I would like to have the chord wire stapled-neat and tidy! Anyway, long winded explanation for convenience.
