## What is Daydream Rail 3D?

A 3D simulator that lets you run your own railway line through real Japanese cities.

Drop waypoints on the map and the route is done: track and viaducts are generated for you, and you ride through real buildings on real terrain. If a railway ran here — this is what it would look like from the cab.

FEATURES
- Tap the map to draw an original line, choosing freely between elevated and ground-level track
- Real cityscapes built from the 3D building data of Project PLATEAU (Ministry of Land, Infrastructure, Transport and Tourism) and terrain data from the Geospatial Information Authority of Japan
- Sixteen real routes included, among them the whole Tokyo Metro network, the Toei subway lines and the JR Yamanote Line — and you can ride them as if they had been built elevated
- Three views: cab, chase and overhead, with the overhead view free to look around by dragging
- Master-controller style notching for forward and reverse; in automatic mode the train accelerates and brakes between stations and stops at each one
- Single or double track, and trains of one to six cars
- Switch between morning, evening and night, and adjust building quality and draw distance — the settings open from the map screen too

Imaginary lines, real scenery. Build the railway journey you have always wanted to take.
