My Christmas train is up and running but it won't make the train sound.  We have tried everything.  Is there something simple we are missing.  We put the 9 V in the coal car and turned the switch   How often does it make sound?

There is a button inside the locomotive that has to be turned on.  Nobody came up with that simple little answer for us and I am suspecting that is the problem with the person who had the same problem as we did. 

It is Item No. 44213.

Yes.  My husband is very handy and he has tried everything.  I
was hoping it would be a little technicality!
 

The only other numbers I could find was an Item No. 90047 and K130916.  It is the Christmas train.

We have shortened the track and it still doesn't work.  Do these numbers mean anything to  you?   Input 120 VAC 60 HZ, Output AC 16V 1000 MA?

I really appreciate your response but it was all Greek to me.  I don't quite know what gauge set I have.  Isn't there a troubleshooting site out there?

Just put together my $400+ train and I can't get it to even run.  Have tried everything.  It is bad that they don't have a troubleshooting forum on this website.  Can anyone help me to see if there is something else I need to do.
