Симулятор железной дороги на Three.js с изометрией и камерой слежения

Build a browser railway simulation game with Three.js. Show a green valley with a river, bridges, a hill, trees, red-brick cities and a network of tracks with junctions linking several stations. Steam locomotives with wagons run along the rails and puff smoke. Offer two camera modes, a free 3D view and an isometric view, plus a follow mode that locks onto a chosen train. Add a clean cream-coloured side panel listing locomotive models with their stats, a top bar with money and income figures, a train selection control and speed settings. Use a muted natural palette with soft daylight and light haze. Trains should move smoothly, slow for junctions and visit stations. Deliver it as a web app that runs from a local server. Done when you can orbit the map, switch cameras, follow any train and see the economy figures update while trains run.
