This motherboard is designed to replace the original lighting board in Intermountain and Bowser diesel locomotives. Created to fit the Intermountain ES44 as well as the Bowser S12, the IB-MB1 will fit a wide array of other locomotives. However, it will require comparing the original light board as there are a few styles of Intermountain/Bowser motherboards which look very similar. Included on this motherboard is a KA2 Keep Alive® for smooth operation over troublesome tracks. Pair with a WOW121 for unparalleled sound and interruption-free performance.

NOTE: This product does not function without a decoder. Pickup an EU621 or WOW121 decoder to use this product.
