Norfolk Southern Horns

Hi, everyone. Which horns does Norfolk Southern use on their Dash 9 and Dash 8 and alike locomotives. Thanks

From what I understand, they use a style most common with the K5LA, similar to what Amtrak uses on most of there units. The also use a P-series but I am unsure if they are used on the Dash-8 and/or Dash-9 series. The former Conrail units in the Dash-8’s use a 3-bell series, most likely Leslie but the K-series is Nathan.

Almost everything they got from Conrail had a Leslie SL3LR.
