By the 40s, most engines on the SP used the 6 chime which was developed in 1930. Some, especially earlier on and on the Sunset route used they high pitched desert 5 chimes. There's also a sacramento long bell 5 chime that some engines used that sounds similar to the 6 chime. Most of the 4-8-4s used handcock 3 chimes (although gs-1s, gs2s, and gs-6s used 6 chimes).
@@Gretschdude1412 Beat me to it. This is effectively the standard whistle on the whole (western) SP system after about 1930, with the exception of the GS-4s and 5s which had to use Hancock 3s due to their immense boiler pressure. Despite the overpressure effect on the whistle, evidently a few GS-4s were mounted with them anyway, 4449 wore an SP 6 chime in the 80s and you can clearly hear the screeching the overpressure caused... music to a railfan's ears, probably not so pleasant to lineside civilians having to listen to it every day. Her twin sister 4450 also apparently had one in the 50s, as her whistle was apparently saved and is occasionally used at railfan events. If you're wondering, the Cab Forwards did indeed use 6 chimes, but they sounded much more like 4449 did in the 80s than 18 sounds in this video; Again, they were pushing just about as much steam out of those whistles as was comfortable to listen to. - Fun fact, the AC's(cab forwards) used an electronically powered whistle switch, rather than a traditional pull-chord, hence they only had two notes for the engineer to play: on or off. So in other words they had no choice but to scream when they blew their whistle. It must've been awesome to listen to. As for smaller engines, anything from the 2-6-0s to the 4-10-2s used these also, again, it was the standard on the _whole_ system... well... everywhere west of the Sunset route that is. T&NO engines like 982 or 745 more likely would've had 5 chimes.
This whistle sounds amazing on the #18.
Is this a whistle that's owned by the V&T or is this a Rizzoli product?
It is a Rizzoli product that was given to the V&T
Any idea what locos this kind of whistle would have been used for on the SP?
I assume most engines Pacific and bigger

The MT Mountains, most of the Pacifics, & the GS-1’s
