STAR BRASS WHISTLES
Below are several recordings of Star Brass whistles that John Bush covers in his article “Union Pacific and the Star Brass 5-Chime Whistle,” in the Autumn 2018 issue of The Streamliner. Click the whistle type below to hear the recordings:
Early Single Note Hooter – This recording represents the sound which would have been made by the early single note whistles. Blown at 200 psi while fitted to ex-LS&I 2-8-0 No. 18 in Antonito, Colorado, 2010.
Star Brass Long Bell Single Note (freight) – Representative of the sound of the Star 6” diameter “plain” whistle used by UP in freight service. Recorded by the late Howard Fogg, this is actually a B&O engine, but the diameter and length of the bell is very close to the Star Brass and thus sounds very similar.
Star Brass 3-Chime (Passenger) – Jim Ehernberger recorded this Star 6” diameter 3-chime when it was still in service fitted to 2-8-0 number 400, circa 1954. One of the very last of these whistles in regular service on Union Pacific.
Star Brass 5-Chime Step Top 1 – Star 5-chime step-top. Heard from several hundred yards away. Whistle fitted to ex-LS&I 2-8-0 No. 18 at Antonito, Colorado, 2010.
Star Brass 5-Chime Step Top 2 – Same whistle, recorded from more than a quarter-mile away, east of Fort Garland, Colorado, blown at 200 psi. This whistle is believed to have been last used on UP 2-10-2 number 5020. It is easy to see why these whistles were hard on crews and resulted in the use of shields.
