1617 TCS Train Control Systems / IB-MB1 Motherboard (SCALE=HO) Part # 745-1617

This HO Scale IB - MB1 Motherboard (Part #745 - 1617) is a great replacement for the original lighting board in Intermountain and Bowser diesel locomotives. With dimensions of 2.82” x 0.69” x 0.33” (72mm x 18mm x 8mm), it fits not only the Intermountain ES44 and Bowser S12 but also a wide range of other locomotives. However, you need to compare it with the original light board as there are similar - looking Intermountain/Bowser motherboards. It comes with a KA2 Keep Alive® for smooth running on troublesome tracks. Pair it with a WOW121 for amazing sound and uninterrupted performance. Note: This product needs a decoder like EU621 or WOW121 to work.

To use this HO Scale IB - MB1 Motherboard, first, make sure to pick up an EU621 or WOW121 decoder as the motherboard won't function without it. When installing, compare it carefully with the original light board in your Intermountain or Bowser diesel locomotive, as there are a few similar - looking models. Once installed, the KA2 Keep Alive® on the motherboard will help the locomotive run smoothly on troublesome tracks. For the best experience, pair it with a WOW121 for great sound. When it comes to maintenance, keep it in a dry place and avoid any physical damage. Check the connections regularly to ensure it's working properly.
