@GameBreaker64 posted:UP 4014's whistle sounds a little odd. It doesn't really sound that much like what you'd expect from a Big Boy. Is it mainly because of wear and tear, or is she using a different whistle from her original? If anyone has information, please let me know!
Is information, all the "Big Three" UP steam locomotives (the 800s, the 3900s, and the 4000s) used/carried the same Manning, Maxwell and Moore deep-tone whistle. Naturally whistles supplied with 280 to 300 psi superheated steam will wear, and wear out. Without any direct information from the current manager at the UP Cheyenne Steam Shop, there really is no way to tell which whistle 4014 has used, or is currently being used (from 3985, or some other whistle in the 'collection' at the shop, or a whistle from a private collector).
