pak64 is a small graphics set for Simutrans, and the evolution of the
original Simutrans pakset.  pak64 includes trains, trams, road
vehicles, ships, and aircraft.  The small 64px graphics require less
disk space and RAM than the larger graphics in other paksets.

If more than one pakset is installed, Simutrans asks the player to
choose one.  The "pak" button is pak64.
