#,,,,,,#,# trains  are  so  constructed  that  they ,,,##,,#,,
#,,,,,#### have to  follow a set path. this path is ,,#,#,##,#
#,,,,#,,,# called a "railway",  which  is comprised ,#####,##,

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

,#,,,##,#, there  are limits for how acute  a curve ###,#,,,##

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

###,##,#,# scattered,  often  put on top  of poles, ,#,,###,##
,,##,####, to  be interpreted by the train drivers. ##,#,,##,,
