A-Train 9 PRIME LINE Launches December 10 With Free-Form Curves And 16-Car Trains
ArtDink announced on September 25, 2026 that A-Train 9 PRIME LINE will launch for PC on Steam on December 10 at 18,480 yen including tax. The city-development railway simulation reworks track and road laying with a new Flexible setting that generates curves and gradients at any curvature or angle, allowing long gentle curves and loop lines. Track appearance can be chosen from four types: ballast track in gray or brown, direct-fastening track, and slab track. Train consists expand to a maximum of 16 cars, up from 10, and coupled trains can run freight formations of up to 32 cars. Curved stations with curved platforms are added, along with two-lane-each-way roads. The Japanese version includes 341 vehicles from JR and private railways and about 600 structure types. ArtDink also plans a special-price campaign for owners of A-Train 9 Ver.1.0 through Ver.5.0, with details to come on Steam News and the official website.
