A directional trigger that causes the leading loco of a schedule-driven train to sound its whistle or horn. Any other locos behind the leading loco (for example, the train engine of a double header or a banking engine at the rear of a train) will not have their whistle/horn triggered.
This asset is a variation of <kuid:647907:101483> 'CDE Horn Trigger Directional'. The original has been altered to suppress triggering by other than the lead locomotive. Thanks to CDE Trainz for the original asset.
