This motherboard is designed to replace the DCC decoder found in DCC equipped Intermountain and Bowser diesel locomotives. Created to fit the Intermountain SD40-2 as well as the Bowser C-636, the IB-MB2 will fit a wide array of other locomotives. However, it will require comparing the original decoder as there are a few styles of Intermountain/Bowser frames 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.
