Ray: I will have to keep an eye open for RRCHW #15.......sounds quite interesting. They put out quite a few obscure recordings; I have one of Wabash Mogul 573 on the Bluffs-Keokuk line.
Burlington 4-8-4 #5632 had absolutely the most soul-satisfying whistle in the early '60's. It can be heard on a couple of the cuts on "Sunday Only". Think it was the regularly assigned whistle on the '32, from regular service days, as the Vinton L. Wright recording of another CB&Q 4-8-4, #5629, leaving Hobson Yard in Lincoln, NE, sounded similar, from 1952.
