Hi Mr Bach-man
Do you have any plans to release the Heisler loco's without the plug and play sound equipment?
Tim
Dear Tim,
The Heislers, like the EM-1, have a decoder installed. The sound module is an option that you may purchase separately.
They will not be available without the decoder, which is dual mode, so the locos will operate on analog layouts.
Have fun!
the Bach-man
