Much like many of the Menards upcoming product posts, this will turn into a guessing game about what this could be.
Lionel recently filed with the FCC on 1/18/2019 for a new Bluetooth based device. Unfortunately the Functional operation guide, the User Manual and other revealing documents have been requested to be kept confidential. Whatever this thing is, it was tested by Shenzhen Alpha Product Testing Co., Ltd. on 12/18/2018 to ensure it will pass FCC requirements.
Could be something big or maybe a new Bluetooth accessory? Thoughts... Wishes?!?!
