I will summarize all the features.
1. The True Blast Plus sound board cannot turn off prime mover sound. All of the feedback that we were getting was that people wanted the sounds. Now you want to turn them off!
The Prime mover sound varies with track voltage. You can adjust the master volume on the board, if you take off the shell.
2. The board is polyphonic. Meaning that all sounds can play at the same time. True Blast II was monophonic only one sound at a time.
3. Sounds are prototypical to loco type. True Blast II was a generic sound set.
4. You can control the length of the horn blast on the True Blast Plus board. The True Blast II was a pre-programmed grade crossing.
Yes you can use the True Blast II board in place of True Blast Plus. Both use the same power plug that connects to the reverse board, so it is an easy swap.
