i just received my n&w class a today and it is a very beautiful engine.  i ran it on dc power and it ran and made sound. i plugged in a bachmann decoder to run on the layout. it still ran and made sound.  i have a nce powercab. i decided to do a consist to run the two engines together. i couldnt quite figure out to operate the consist, so i tried to start running the trains seperately again. it would run, but it wont make sound. both the class a and the santa fe.  anyone got any suggestions?

how do you get the tender shell of of the ho J?
