It's a beautiful locomotive and runs like a charm. I removed it from the track with the intent on packing it away for a bit. The tether will not come out from the slot at the back of the engine. I wrote to Bachmann about this and didn't get much of a response. Maybe I didn't address the problem clearly enough. In either case, I had to put engine and tender back in the box still tethered. Yep, I know there's a a small tab to push that is supposed to release the tether from the engine. It isn't working. This type of issue makes me regret my purchase.
