Nathan Airchime CSX YN2 K5LA Hybrid. This is actually A very nice sounding Train Horn Considering it is a hybrid. At some point the shop replaced a dead number 5 with an additional number 3a. This Horn is in its original take off shape/sound. A traditional K5LA has bells
1,2,3a,4,5. This hybrid wears numbers 1,2,3a,3a,4a giving it a slightly deeper tone. #csxt #airhorn #trainhorn
