BlueRail Trains – Onboard sound for $10

This video shows how to add a mini-bluetooth speaker to your Bachmann E-Z App&TM; or original BlueRail Blue Horse Train for onboard sound. This solution can only be used for a single loco, but the cost, quality, and ease of implementation make it a great solution for what it is. This does NOT presently work on the new BlueRailDCC boards, which achieve onboard sound via a DCC decoder.
