¨^~^%@£### 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 ££@@%%^~^¨

¨^^~~%%£## for  something to happen, far away. this ##£%%~~^^¨
¨^~^%@£### is  signaled  by  red or  green  lights. ###£@%^~^¨

¨^~^%@£### often  this  proves to  be  the  shorter ###£@%^~^¨
