Hello,
I would like to know on Canadian National Railways GP7 and NW2 locomotives, what type of air horns (Nathan etc.) were used on these models.
Thank you.
Serge
I'm sure those models were delivered c.1950 with single chime "blat" airhorns.
IIRC in the 1950's (or very early 1960's?) Canada passed a regulation that all Canadian engines had to have a three-chime airhorn. Not sure if it had to be from the same manufacturer or just a three-chime set to the same notes, or what. The idea was that people would have an easier time recognizing the engine's airhorn grade crossing signals if they all sounded the same, so they couldn't be mistaken for say a truck airhorn or whatever.
Hello Stix,
Thank you for the info, it's greatly appreciated.
What type of three-chime air horn were installed, Lesly? Nathan ?
The reason why I'm asking this question is that I want to program my loco with the prototypical air horn.
The most common one on CN would be a K3L or some some variant there-of ....
Loksound has the only variant of the K3L that truly sounds like the CN horn to me. The others don't have the one higher pitched bell sound to them. They sound more like a US K3L.

Hello Mark,
Thank you for the info,
I'll be programming the air horn in a Tsunami 2 decoder.
I'll look it up in their list.
I might be wrong but after looking at CNR EMD NW2 photos in the book "Canadian National Railway Diesel Locomotives Volume One" I think that those locomotives were equipped with Nathan single chime horn.

Guy Papillon I might be wrong but after looking at CNR EMD NW2 photos in the book "Canadian National Railway Diesel Locomotives Volume One" I think that those locomotives were equipped with Nathan single chime horn.
When those engines were new, they did come with a single chime horn. The K model was first introduced in Canada around 1954. Holden Ltd. of Canada produced the K3L horn. It is a sand cast horn with #1, #2 and #3 bells. CP Rail and Canadian National used this horn. Today’s version is a die cast horn manufactured by Nathan. The L designation means low profile base.
Hello Guy and Mark,
Thank you very much for the aditionnal info, it's very much appreciated.
Il searched the web for prototypical Air Horns on theses CNR locos but didn't come up with the info I was looking for.
Now I'll be able to program my decoders with the correct Air Horn.
Have a great day.
I am NOT an expert on the horn issue, esp on CNR et all.Back in the day, c. 1950, a TRUE Yard Diesel usually had a smaller bleating horn which sounded akin to a Sheep-critter, BAAAAAHHH!, as here.

BUT this does not mean they did not come with them.The first bunch of Canadian PACIFIC GP7s had Honkers. You could see plumbing on them, after change. When CPR got rid of their Honkers on Diesels, they appear, ( NOT Confrmed in WRITING. ) the Honker Horns cascaded down into MoW service on Spreaders esp. ( There is one here, right now, Cab behind the wings, and all, Honker atop. )This could turn into a saga, and I still have to do dishes, feed the cat, sweep the floor and so on.This one is Engine Unknown for train orders??http://trainweb.org/oldtimetrains/photos/cnr_diesel/0000.jpg Back to Cut Off, Wire Drawing and that some other time. Not in the mood. Thx for data on Universal/Economy Valve.Thanx for CORRECT pronunciation of 'Boxpox'. Arthritis pain BAD, tonite.Sorry.
Hello NDG,
Thank you so much for the very detailled informations; with the photos you can clearly see which horns were used on the NW2 and the GP7.
As for the NW2 I will opt for the "Honker" since it will be assigned to yard duties only and the GP7 will be equiped with the 3 chime horn.
Thank you once again and sorry to hear about your Arthritis.
