###¨#¨#¨¨¨ 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 ¨#¨¨¨#¨¨#¨
¨########¨        toward the train drivers!         ##¨¨##¨###
