Zero Gravity Third Rail®

Mass Transit Third Rail Anti-icing

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.

Zero Gravity Third Rail® anti-icer, for the third-rail surfaces on mass transit trains to keep them free of ice, is delivered by the Ice-Slicer® Third Rail Spray System. Third-rail anti-icing protection is critical because ice on a third rail will not allow sufficient electrical contact, thereby causing power problems which will keep a train from operating. Treating the third rail with Midwest’ Zero Gravity Third Rail will help keep mass transit running on schedule and provide greater 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 delays and 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.


Zero Gravity Third Rail Benefits

  • 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
