Freight Sound Effects ?.

They either have passenger or freight sounds not both sounds like yours has passenger sounds.  

I guess I just assumed wrong, being a steam engine it would have freight sounds. So when you purchase one you have your choice.

You can download different sound files for most MTH locomotives if you want to switch from passenger to freight or the other way.  Since the Hudson was primarily a passenger locomotive, I'd expect the stock sounds to be passenger based.

I have a Rail King 4-6-4 Hudson Steam Eng. ...

the main purpose of the pilot truck on steam locomotives is to steer (nudge) the front end when entering a curve when running at mainline speeds.  at higher (passenger consist) speeds, 4 wheel pilot trucks are more effective in this role, so generally speaking, 2 wheel pilot trucks were more often found on smaller driver, slower speed freight locomotives, while 4 wheel pilot trucks were mostly found on larger driver, higher speed passenger and dual service locomotives.

with the 4 wheel pilot truck and 79" drivers, as GRJohn already mentioned, NYC Hudsons were primarily used in passenger service.  if you want a freight locomotive from the same era, look at wheel arrangements such as a Mikado (2-8-2) or Berkshire (2-8-4).
