We have a radio control and an older powered Big Hauler. Is the sound quality the same or do the newer ones sound better?

I have install the remote card in our 4-4-0 while deciding what power and sound system we are going to use. It works but I am wondering if the newer one would sound better.

  Thanks Bob

We perchased a used G 4-4-0 a year ago at a train show. Is there a way we can get an owner/user's Manual?

We haven't ran it for a while. It is fine with the loco and tender. If you add a couple of cars, the loco develops a high pitched intermittent squeal.

Is that typical? Where should we lubricate to stop it?

Thanks BnB
