Train Control Systems 1620 IB-MB2-NC Motherboard, Intermountain & Bowser Locos is an exact Train Control Systems catalog item.
Verified details

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.
