¨¨~=*%£&## 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.            #&£%*=~¨¨¨

¨¨~=*%£&## 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. ##&£%*=~¨¨

¨~=*%£&### often  this proves  to  be  the  shorter ###&£%*=~¨
