,&,,,,,,,, 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 &&&,&,&,&,

&&,&&,&&&& 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. ,,,&&,&&,&
