##£$§:=^,, trains  are  so  constructed  that  they ,,^=:§$£##
###£$§:=^, have to follow a set path. this path  is ,^=:§$£###
##£$§:=^,, called a  "railway", which  is comprised ,,^=:§$£##
###£$§:=^, of two metal rails, hence  its nickname. ,^=:§$£###
##£$§:=^,,                                          ,,^=:§$£##

##£$§:=^,, wheels of  the train and the rail metal, ,,^=:§$£##
###£$§:=^, there are limits  for how acute  a curve ,^=:§$£###

###£$§:=^, the  ground  under  the  rails   can  be ,^=:§$£###
##£$§:=^,, sloped. thus a  railway is often not led ,,^=:§$£##
###£$§:=^, on top of hills, rather  through them in ,^=:§$£###
##£$§:=^,, tunnels   (if   they   are  large),   or ,,^=:§$£##

##£$§:=^,, rails, but not  too close, or they  will ,,^=:§$£##
###£$§:=^, be  cut down  by  the  railway janitors. ,^=:§$£###
##£$§:=^,, there  will  be  plains,  and  bodies of ,,^=:§$£##

##£$§:=^,,       the way, there is information      ,,^=:§$£##
###£$§:=^, scattered,  often put on  top of  poles, ,^=:§$£###
##£$§:=^,, to be  interpreted by the train drivers. ,,^=:§$£##
###£$§:=^, different  parts  of  the  railway  have ,^=:§$£###

##£$§:=^,, sometimes, trains  have to stop and wait ,,^=:§$£##
###£$§:=^, for something to happen, far  away. this ,^=:§$£###
##£$§:=^,, is  signaled  by red  or  green  lights. ,,^=:§$£##

###£$§:=^, often  this  proves  to  be the  shorter ,^=:§$£###
##£$§:=^,, path between  two  points.  however this ,,^=:§$£##
