2005年9月23日 · Horn Installation on NYC GP-7 and GP-9. Does anybody know what was installed on these early geep locomotives delivered to the New York Central? Photos of GP-7s show a single horn on the engineer’s side (right side) of the long hood facing forward and a single horn on the fireman’s side (left side) of the cab facing back along the short hood.

The EMD GP9 is a four-axle diesel-electric locomotive built by General Motors' Electro-Motive Division between 1954 and 1959. The GP9 succeeded the GP7 as the second model of EMD's General Purpose (GP) line, [ 1 ] incorporating a new sixteen- cylinder engine which generated 1,750 horsepower (1.30 MW). [ 2 ]

2012年3月4日 · Where can I find or who would know what types of horns were used on specific locomotives and roadnames in conjunction with years of service. I am looking for horn info on GP7,GP9,GP30,GP35,SD35,GP38,GP40 & -2, as well as SD40 as used on the Chessie System throughout its limited life.

Engines built in 1952 had horns behind the two exhaust stacks: 8500-8512 and 8797-8806. Engines built in 1953 had horns in front of the exhaust stacks: 8545-8587. I thought the GP9s all came with Leslie RS3L horns mounted forward of the dynamic brake blister.

Did the C&O use a slightly offset mounting position for the horns on its GP9 units? I ask because I recently got an Athearn Genesis GP9 and the horn seems to be in the right location on the short hood (engineer's side), but the bells of the five-chime horn are angled slightly toward the middle of the hood rather than firing straight ahead.

2025年1月5日 · Air Horns. The first GP7s, numbered UP 700-709, delivered in February and March 1953, had their horns mounted near the rear exhaust stack (long hood forward). Photos of UP's fleet of GP9s when they were new show that their air horns were originally located at the top of the cab roof, at the centerline of the locomotive.

Subject: [PRR-Modeling] GP9 Airhorns Working on some HO GP9s and would like to verify the type of airhorns used on the 36" fan unit(Phase II). From what I can see in the varous PRR books I have, looks like Leslie S-3L but can't tell if all trumpets are facing forward as the horns are usually in a shadowy location.

2013年1月16日 · Yes, the aftermarket Tsunami has the Nathan M3 horn. The factory installed version (in the D&RGW GP9's) does not, factory decoders usually come with a few less features. I purchased 5922 without sound and plan on adding aftermarket Tsunami so I can have the M3 horn. ... > options with these decoders. ...

2018年11月11日 · As far as the Tsunami decoder, the complaints are mainly with the Tsunami I decoder which people complained of weak horns and the OEM version often did not have the correct horn for the model. Rio Grande experts complained the sound equipped GP9 from Genesis did not have the correct horn sound for the D&RGW GP9’s.
