.#.#.#..#. 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 #.#.#.#..#

.#.#.#.##. 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 #.#.#.#..#

.#.#.#.##. 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.         #.#.#.#..#

.#.#.#..#. IS  SIGNALED BY  RED  OR  GREEN  LIGHTS. #.#.#.#..#

.#.#.#..#. PATH BETWEEN TWO  POINTS.  HOWEVER  THIS #.#.#.#..#
.#.#.#.##. IS  FROWNED  UPON,   AND  VERY  IMPOLITE #.#.#.#.##
