Thunderbolt, previously known as Pippin, is a wooden roller coaster located at Kennywood amusement park in West Mifflin, Pennsylvania.

It was later renovated for the 1968 season, which involved a major track expansion designed by Andy Vettel.

[1] In 1991, the tunnel located at the end of the first dip was removed, allowing for a view of Steel Phantom.

Renovation of Phantom's Revenge resulted in Thunderbolt being closed for a few weeks in 2001 so that the new ride could be built through the structure.

Reaching a maximum speed of 55 mph (89 km/h), the ride takes 1 minute and 40 seconds to complete its circuit.

A unique feature of Thunderbolt is that after departing from the station, the train does not immediately ascend the lift hill like most coasters.
