This motherboard is designed to replace the original lighting board in Intermountain and Bowser 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 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 unparallelled sound and interruption free performance.
NOTE: this product does not function without a decoder. Pickup an EU621 or WOW121 decoder to use this product.
