##¶&$%;,,, trains  are  so  constructed  that  they ,,,;%$&¶##
###¶&$%;,, have to follow a set path. this path  is ,,;%$&¶###
##¶&$%;,,, called a "railway",  which  is comprised ,,,;%$&¶##
#¶&$%;,,,, of  two metal rails, hence its nickname. ,,,,;%$&¶#
¶&$%;,,,,,                                          ,,,,,;%$&¶
&$%;,,,,,, because  the low  friction  between  the ,,,,,,;%$&
$%;,,,,,,, wheels of the train and the rail  metal, ,,,,,,,;%$
%;,,,,,,,, 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.            ,,,,,,,,,,

$%;,,,,,,, rails, but  not too  close, or they will ,,,,,,,;%$

¶&$%;,,,,, there  will  be  plains,  and  bodies of ,,,,,;%$&¶

###¶&$%;,, trains  go by  day and by  night.  along ,,;%$&¶###
##¶&$%;,,,      the way, there is information       ,,,;%$&¶##
#¶&$%;,,,, scattered,  often put  on  top of poles, ,,,,;%$&¶#
¶&$%;,,,,, to be interpreted  by the train drivers. ,,,,,;%$&¶
&$%;,,,,,, different  parts  of  the  railway  have ,,,,,,;%$&

,,,,,,,,,, for something to happen, far away.  this ,,,,,,,,,,
