Train horns! is a video series that listens to different types of air horns used on North American locomotives at railroad crossings.
Part 3 features the Nathan Airchime K5LLA, which is incredibly loud. The standard K5LLA uses the 1L, 1, 2, 3A and 4A bells and is the horn of choice on new EMD locomotives, such as the SD70M-2 and SD70ACe, while the K5HL is for GE's, becoming one of the most common train horns in the country.
Heritage Units are exluded from this video as all 20 are featured in there own video here: • Norfolk Southern's 20 ...

Since 2004, like any other horn, some have appeared on other locomotives models; we'll see several examples in this video. Some modified versions of this horn exist, particularly on the MEC 3400's or GO Transit, often referred to as K5LL or K5LLB depending on the bell utilization.
The K5LLA, along with the K5HL, use a 1L bell that came onto the market in 2004 as a response to a federal mandate that established a minimum and maximum decibel rating, which ultimately led railroads, most notably CSX, to rid older horns off of their locomotives, particularly Leslie 3 and 5 chime horns. In reality, the K5LLA and K5HL are often much louder than the Leslie horns. Sound-dampening techniques include turning several bells or the entire horn backwards. In any case, the most typical K5LLA arrangement involves turning only the 1L bell backwards.
