So half of Lightning Rod has recieved Iron Horse treatment due to issues with the track not being to able to withstand the sheer speed on some sections. Here is a rough picture of what sections are still topper track.
It is now open, though it has been said the ride is still incredibly problematic, primarily due to its launch.
The ride has been shown to still have rollbacks, and when it rolls back it usually does not open for the rest of the day..
I honestly do not know what Dollywood are going to do next. The ride has been such a pain since 2016. Great coaster in terms of the actual ride, but absolutely a nightmare. They asked for a RMC, not a intamin.
