Interview Spotlight: Peter Jones, Greenbrier
Greenbrier recently unveiled a newly designed covered hopper railcar for grain transport (as shown on the cover of this issue of Global Railway Review). Here, Peter Jones, SVP of International Engineering, Product Development & Automation, explains the railcar’s state-of-the-art elements, plus its safety and environmentally friendly characteristics.
The railcar includes a hatch system known as the Tsunami Gate™ – what is different about this and what benefits does it bring?
Our new covered hopper railcar is designed for grain service and has a capacity of 5,185ft3. We have taken all of the area between the trucks and created one long discharge gate. Tsunami Gate™ provides numerous benefits – primarily shortening the railcar length by 10 per cent, enabling a railroad to haul an additional 12 railcars without adding a locomotive. The gate lowers the centre of gravity, providing a smoother and more efficient ride. The large side skirt – similar to what is seen on road among semi-trailers – provides better aerodynamics, resulting in a 53 per cent drag reduction. Greenbrier modelled the railcar with Boeing to simulate the commutation for fluid dynamics.
