Lionel Union Pacific #4520 LionChief Switcher Locomotive & Tender

Lionel Union Pacific #4520 LionChief Switcher Locomotive & Tender with Rail Sounds, Puffing Smoke, Crew Talk, and Bluetooth Remote. I recently purchased this off of eBay. It has the best whistle sound I've heard and operates beautifully. Originally it was part of set 6-1923040 that came with a tank car, boxcar and a caboose but I purchased this as a set take out with no box. The locomotive also works with the LionChief remote smart phone app. This is one of the early LionChief Locomotives and does not have the remote control couplers that can open and close with the remote. I miss that feature but for the price it's a nice buy.
