¨¨¨¨¨¨¨¨¨¨ 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. ¨¨¨¨¨¨¨¨,=

$*\=,¨¨¨¨¨ wheels of the train and the rail  metal, ¨¨¨¨¨,=\*$
#$*\=,¨¨¨¨ there are limits for  how acute a  curve ¨¨¨¨,=\*$#
@#$*\=,¨¨¨ can  be, and even more so  for  how much ¨¨¨,=\*$#@
#@#$*\=,¨¨ the  ground  under  the   rails  can  be ¨¨,=\*$#@#
##@#$*\=,¨ sloped.  thus a railway is often not led ¨,=\*$#@##
#@#$*\=,¨¨ on top of hills, rather through them  in ¨¨,=\*$#@#
@#$*\=,¨¨¨ tunnels   (if   they   are   large),  or ¨¨¨,=\*$#@

,¨¨¨¨¨¨¨¨¨ 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. ¨¨¨¨¨¨¨¨¨,
