,#,##,,,## 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. ,,#,,,,,,,
