![The image displays a black-and-white line drawing of a high-speed train. The train is depicted in a front-three-quarter view, highlighting its sleek, aerodynamic design with a pointed nose cone. Visible details include a large front windshield, a row of rectangular side windows, and headlights near the bottom front. Faint grey shading on the lower side of the train provides a sense of volume. The illustration is set against a white background, with a thick black horizontal line running across the very top edge of the frame.](.ard-r2150-20250925/662a2cc9d603a8fbf034f326075aca5c0834f6ef0a44d1c781da88c09ba4a84d.jpg)
