This HO scale motherboard (Part # 745 - 1622) is a great replacement for the original lighting board in Atlas and Kato diesel locomotives.

Pair it with a WOW121 for top - notch sound and uninterrupted performance. Note: A decoder (like EU621 or WOW121) is required for this product to work.

To use this HO scale motherboard, first make sure you have a decoder like EU621 or WOW121 as the product won't function without it. Remove the original lighting board from your Atlas or Kato diesel locomotive and install this new motherboard in its place. It comes with a KA2 Keep Alive® that helps the locomotive run smoothly on difficult tracks. For the best experience, pair it with a WOW121. When it comes to maintenance, keep it clean and free from dust. Avoid exposing it to extreme temperatures or moisture. If you encounter any issues, check the connection with the decoder and the locomotive.
