Gravity Group Engineers Unveil Next-Generation Wood Coaster Train


The engineers at The Gravity Group started with a blank sheet of paper and ended up with the next generation of trains for wooden roller coasters.

"Timberliners incorporate new technology – such as magnetic braking and restraint monitoring – that wasn’t even imagined when wooden coaster cars were first developed, " says Michael Graham, lead engineer for the project. "When it comes to wooden coasters, The Gravity Group has more experience designing rides than anyone. We’ve applied that expertise in designing trains that addresses every facet of roller coaster performance and function – from maintenance and safety to rider enjoyment and capacity."

Timberliners are designed to be compatible with existing wooden coasters, allowing a park to upgrade their roller coasters with Timberliner trains.

Key features of the trains include:

Single-bench design
Shock absorption and ergonomic styling
Unparalleled ability to smoothly navigate the track for decreased train & track maintenance
Innovative restraint system for unsurpassed safety and security
Restraints designed for higher throughput
ASTM F2291 Class 5 restraint with integrated monitoring
On-board sound system capable
Magnetic braking capable
Launch system capable 

Timberliners are available for purchase in time for the 2009 operating season through The Gravity Group’s sister company, Gravitykraft.
