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

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