NIGHT BEFORE CHRISTMAS TRAIN SET HAS NO SOUND

[drdowling1]

I set up this g scale train set turned on switch on the bottom of the tender car, put a new battery in, and plugged in the wire to engine and turned on the switch.  I have no sound.  Is their an easy fix for this or do I have to send a new train set back for repairs.  The engine runs fine but no sound.

• Check is the plug labeled "SOUND" correctly orientated and firmly in the socket labeled "SPEAKER"?
  
• Check the polarity of the battery, the label maybe reversed on the battery compartment lid.
  
• Double check position of both on/off switches.
  

Still no sound - contact Bachmann Service Dept
