,#,##,,#,, 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 ,#,,#,,,##

###,,#,##, is  frowned  upon,  and  very   impolite #,,#,,#,,,
