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

,,,,,###,, often  this  proves  to be  the  shorter ,,,,,,#,##
