Zero Gravity Third Rail®

Zero Gravity Third Rail uses a NASA Smart Fluid technology we call Zero Gravity, co-developed by NASA/Ames Research Center and Midwest. Applied before a storm, it prevents ice and snow from bonding to the third rail, keeps your trains on schedule, and helps maintain maximum safety for passengers.

Prevent Third-Rail Icing

Given that it takes five to 10 times more product to remove ice once it has formed than to prevent it from forming, using environmentally-friendly Zero Gravity Third Rail prior to and during a severe storm will not only prevent shutdowns but also cost less money. More effective than electric heaters, Zero Gravity Third Rail holds fast to vertical surfaces and remains in place, triggered into action by sleet, rain or snow.


  • Eliminates power loss and stalled trains
  • Defies the effects of rain, sleet, snow, wind and gravity
  • Does not conduct electricity or cause shorting
  • Reduces wear and tear on “contact shoes”
  • Biodegradable/non-corrosive
  • No electrolytes/non-galvanic
