I just purchased a Williams o gauge santa fe gp-9 locomotive and the true blast horn does not work.
I am new to Williams and looking for any suggestions on what may be wrong.
Is there a battery or sound board?
Before I start tinkering, I would like input from those who may know about these locos.
Thanks, as any input would be appreciated

I just purchased a used Holiday Special 2 Set Box and I can not get the Loco sound to work or the light in the tender to work.
I plugged in the 2 terminals from the tender to the loco but no sound or light. There is also another switch on the loco which i tried in several positions. The Loco light works and the tender seems to have a volume switch but still no sounds.
I do not have a manual and I  do not own any other large scale trains. Any help would be appreciated.
Thanks
