A freeware, cab-view only train simulator originally designed in Japan and
since translated into English by enthusiasts across the globe.

Looking out through the viewport of a train cab, you must drive your train
trough a route, making your scedule and obeying the rules of the rails.

The game runs at 640×480 and can be controlled via keyboard, joystick, or a
Japanese controller that resembles a train’s actual controls. Initially
designed only around Japanese commuter routes, others have added everything
from the New York City subway to slow freight treks in places from Australia
to Germany.

The game is free for download from either the ‘company’s’ site, or from an
English affiliate.
