Is there a free source of loco sound samples?

Has anyone any information about a free downloadable archive of sound samples of locos? I would be looking for as large (lengthy) samples as possible to avoid obvious repetition in a loop as much as possible, rather than sound effects clips measured in seconds.

Oh, I see now there are some commercial suppliers of audio cassettes. Are there any particularly good suppliers of CDs with good long sound samples of locos?

Do a Google for “train sounds”. There’s a bunch of sites. I did the same thing a while back and could play them on my computer in the train room.

There is a good idea! Google!

Once you have the sounds you might want to try AirHorn from Brinston Sound Images?
