MSRP: $49.95


Buy TCS 21 Pin Decoders Here

The TCS IB-MB2 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.

  • TCS Item Number: 1618
  • This Motherboard Configured with Plug Receptacles
  • Shipping Weight: 1 oz.

*NOTE: this product does not function without a 21 pin decoder. Currently the TCS-1527 WOW121 21 pin decoder only has EMD sound files on it, but we expect an update soon on this decoder to include the GE, ALCo & Baldwin sound files.
