This one has no real-world original. Viendor describes it as a 1940s-style luxury train cabin, its first-class interior recreated in PU leather panels, wood and stamped metal under warm yellow lights. The window is what it was built around: a mechanical system behind it carries a landscape past, so that the compartment seems to be moving. Viendor calls it the first book nook with a fully moving scene.
Viendor began in 2019 as Polywoods, three engineers and architects designing products and learning to sell them at once. By 2020 it was two people in a nine-square-metre workshop. Its founder, Ngo Quoc Hoang, is based in Hanoi. For a time it designed and manufactured kits for Anavrin, which sold them, and Hoang has said many of the products sold in that partnership were Viendor designs. Anavrin itself has posted the 1940s Train Cabin as "our DIY kit". The partnership ended when Viendor could not raise capacity and quality fast enough for Anavrin, and the workshop began selling direct, first as BookNook.vn and Book Nook Global, then as Viendor — "Vi" for Vietnam — because "book nook" had become too generic to protect.
Viendor says the Train Cabin was developed in 2022 over nine months, three of them and eight prototypes spent on the moving scenery alone, and that the model was later completely remade with refined metal details and an easier build. The kit has 536 pre-cut, pre-coloured parts in aromatic birch, acrylic, metal and PU leather, some of them with adhesive already applied, and builds to 21.6 × 15.3 × 23.7 cm. It comes with an LED light set on a 5 V / 1 A supply and an instruction manual; knives, scissors and tweezers are not included. Viendor rates it intermediate, about six to seven hours.
