Nashville N Trak
Ken Herrell, Mike Curtis

• A large number of us wanted DCC
• The Decision was not unanimous
• DCC and DC must "Co-Exist Peacefully"
• There must be Minimum Changes to the existing Modules

• The Co-existence of DCC and DC is Primarily a Problem of security
• Traditional N-Trak Wiring Standards are Inadequate for Large DCC Setups

• Why A Simple Control Panel is Inadequate
• Our Power Distribution Scheme
• The Trainmaster Panel
• The PM-4 and Alternates
• The Octopus
