If there was any complaint, it was that the sound was kind of low (never noticed that at home).

Francine, I had the same issue with my Polar Express at a couple of local shows here in Wisconsin during the holidays. What I did to improve the output on my set was to remove the stock speaker and install the "Fat Boy" speaker that is sold by Electric Railroad. It is a simple change, just remove the tender shell and unsolder the two wires from the speaker and remove it, solder the wires to the Fat Boy. You will have to check the position of the new speaker for clearance of the tender shell. I needed to file a bit off of one side of the speaker enclosure but you will be able to fasten the new speaker to the tender with two of the four screws that mounted the original speaker. This will greatly improve the volume of the sounds. The Fat Boy sells for about $10.00.
