This motherboard is designed to replace the original lighting board in Intermountain and Bowser locomotives. Created to fit the Intermountain U18B and 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 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.
COVID-19 INFO: Arizona has issued an ordinance for us to shelter in place through the end of April. Orders will be accepted and processed, hopefully, with no change in service. Thank you for your patience! Dismiss
