Amtrak's AcelaTM high-speed train will redefine rail service in the U.S. and its sleek signage reinforces this bold statement. Instead of relying on a logo for recognition, the "airfoil" shape of the back-to-back curved panels evokes an overall effect of speed and aerodynamics that creates a singular statement of three-dimensional form. The signs fulfill the passenger's need for orientation and schedule information and link these services directly to the brand.
