A: The Model 230 and 630 train horns that come in our HK7 & HK8 Systems are some of the loudest horns we carry. The output is about 153-154 db at 150 psi. However if you use the Model 6880 BlastMaster upgrade, (supplies 2 extra solenoids, fittings and tubing so each trumpet will have its own solenoid) the output will go up to about 157 db. The only thing louder is our Model 730 Demon™ Train Horn that comes in our new HK9 system which can also be upgraded, but with our Model 6890 Ultra BlastMaster upgrade – to produce 158.8 dB!
