I think the train whistle is a lot harder than the yodel! I saw a video with Pete Seeger singing the Blues Yodel #1 ("T for Texas"). He does a nice job; but he ruins it by the unsucessful attempt to make a train noise. I don't think Rodgers had a train whistle in that one anyway.

By the way there is a video with Rodgers singing three songs. He has a beautiful little Martin guitar with his name inlaid on the fingerboard. He sings three songs: "Waiting for a Train" which is good train song, "Daddy and Home", which is one of his soppy sentimental ones, and "Blues Yodel #1", which I think is one of the better blues yodels.

The name of the video is "Times Ain't Like They Used To Be" put out by Yazoo.
