Patented trains for precision ballast placement
GPS Ballast Train Technology
Herzog’s high-speed GPS ballast trains are used to unload ballast with pinpoint accuracy and reduce time spent on your track.
The Programmable Linear Unloading System (PLUS) or SMART train can be used ahead of tie gangs, steel gangs, surfacing projects, or for new construction on skeletonized track.

Safe, efficient technology
Our trains provide a site-specific solution to ballast unloading without the need for ground personnel on dangerous and unstable walking surfaces of ballasted track and without the harmful effects of silica dust inhalation.
PLUS & SMART Train Features
-
SMART cylinders and
flow sensorsCylinders funnel ballast into the shoulder or in track centers, as determined by the contracting railroad. The sensors determine proper ballast flow which helps prevent unbalanced loads, skips, or blockages.
-
Inertial system Replaces the use of a standard GPS antenna which dramatically improves placement accuracy.
-
Spreads through tunnels and mountainous areas Allows for seamless ballast spreading through areas where GPS outages occur.
