Software Updates

Older software may be upgraded with the latest software on BlueLine, Paragon 2, and Paragon 3 decoders.  The latest software release may have a feature or an enhancement that would increase your model railroading enjoyment.  You may choose to send in your locomotive or just your Paragon 2 sound unit board.  If you ship the circuit board, please place the board in an anti-static bag and ship the board in a box.
