.#.##.#.#. trains  are  so  constructed  that  they .#.##.#..#
.#..#.#.#. have to follow  a set path. this path is .#..#.#.##
.#.##.#.#. called a "railway", which  is  comprised .#.##.#..#
.#..#.#.#. of two  metal rails, hence its nickname. .#..#.#.##
.#.##.#.#.                                          .#.##.#..#
.#..#.#.#. because the  low  friction  between  the .#..#.#.##
.#.##.#.#. wheels of the train and the rail  metal, .#.##.#..#
.#..#.#.#. there are limits for how acute  a  curve .#..#.#.##
.#.##.#.#. can be, and  even more so for  how  much .#.##.#..#
.#..#.#.#. the  ground  under   the  rails  can  be .#..#.#.##
.#.##.#.#. sloped. thus a railway is often  not led .#.##.#..#
.#..#.#.#. on top of hills, rather through  them in .#..#.#.##
.#.##.#.#. tunnels  (if   they   are   large),   or .#.##.#..#
.#..#.#.#.            artificial chasms.            .#..#.#.##
.#.##.#.#.                                          .#.##.#..#
.#..#.#.#. there will be trees on the  side of  the .#..#.#.##
.#.##.#.#. rails, but not too close,  or  they will .#.##.#..#
.#..#.#.#. be  cut  down  by the railway  janitors. .#..#.#.##
.#.##.#.#. there  will  be  plains,  and  bodies of .#.##.#..#
.#..#.#.#.                  water.                  .#..#.#.##
.#.##.#.#.                                          .#.##.#..#
.#..#.#.#. trains  go by  day and  by night.  along .#..#.#.##
.#.##.#.#.      the way, there is information       .#.##.#..#
.#..#.#.#. scattered,  often  put on  top of poles, .#..#.#.##
.#.##.#.#. to be interpreted by the train  drivers. .#.##.#..#
.#..#.#.#. different  parts  of  the  railway  have .#..#.#.##
.#.##.#.#.          different speed limits.         .#.##.#..#
.#..#.#.#.                                          .#..#.#.##
.#.##.#.#. sometimes, trains have to stop  and wait .#.##.#..#
.#..#.#.#. for something to happen, far  away. this .#..#.#.##
.#.##.#.#. is  signaled by  red  or  green  lights. .#.##.#..#

.#.##.#.#. many people follow  the  rails by  foot. .#.##.#..#
.#..#.#.#. often  this  proves  to  be  the shorter .#..#.#.##
.#.##.#.#. path  between two  points.  however this .#.##.#..#
.#..#.#.#. is  frowned  upon,  and  very   impolite .#..#.#.##
