The Lionel 6-2162 O Gauge Automatic Crossing Gate & Signal is a realistic accessory designed for model railroads. This signal is specifically made for O gauge model trains and is suitable for hobbyists aged 17 years and up. With its automatic crossing gate and signal functions, this product adds an extra element of authenticity to train layouts, making it an essential part of the model railroad enthusiast's collection. The Lionel brand ensures quality and attention to detail, making this accessory a must-have for any train layout. I believe this item has never been used.
