This is William's 2011 Ford F150 and this is his Train Horn Install. The kit installed below on his truck is our Conductor's Special 228V Train Horn Kit. This kit contains our Shocker XL Train Horns, that are packed with intense loudness and authentic Train Horn sound! With the tank and compressor unit not be fully sealed it needed to be mounted somewhere out of the elements. So placing these units in a toolbox as he did below is perfect for this system.
