Tremors
In 2010, Tremors was the first coaster to get new "topper track" from Rocky Mountain Construction of Hyden, Idaho.  The system replaces the top two layers of wood with steel.  This cuts down on track maintenance as well as gives a smoother ride to anyone riding the coaster.  

I talked to one of the people doing maintenance on Silverwood's coasters, and he said that nearly 700 feet of track at about the halfway point of the ride was replaced with "topper track" and it has performed well.  It gives a nice, smooth ride and makes for a little less regular work on that portion of track.
