Dedicated to Sharing the Heritage of Redwood Empire Railroading
Just thought I'd get a blog started on the different horns in use on the NWP both past and present.
Pictures and descriptions soon to follow.
There are several different horns in use on the NWP currently but the only horn actually owned by the railroad is a Nathan Airchime K3LA. It uses a common trumpet combination of 1 2 and 4A and sounds just like 70% of the mainline railroad power running out there. And that is the reason why it isn't used much. K series horns are loud, brassy sounding, and above all else way too common.
The NWP's K3 horn came with 2009 when it was shipped out here. In early 2013 it was cleaned and painted as can be seen in the photos I've posted. The K3 isn't used much as crews think it's a little on the loud side, plus the Roadmaster Of Horn Selection just doesn't like it. He prefers SP heritage horns (I don't fault him for that) and uses those when he can.
Another horn in use on the NWP is the permanently welded on new cast Nathan Airchime P3 horn used on the 1922. This horn is privately owned and on loan to the NWP.
This horn uses the classic trumpet combination of #1, #2, and #4. Again this is a new cast horn as opposed to what's known as an old cast horn. Some time in the late 70s or early 80s, Nathan's P horn pattern was beginning to wear out. A new pattern was made but it was ever so slightly different. Most if the trumpets sounded similar but were a few hz off from the original (old cast) trumpets. P3 models sounded pretty close to the old horns but the P5 was a night and day difference.
Southern Pacific was a big user of model P and M horns. Both new and old cast P horns could be found on the SP all the way up to the end. Since the official colors of the new NWP are SP's old scarlet and gray, it's only fitting that the horns are the same as well.
