&&&,,&,,,& 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 &&&,,&&,&,
&,&&,,&,,,            Artificial ChasmS.            ,,&,&,&&&&

&,,,&&&&,, 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 Speed Limits.         &&,&,,&&&,

,&,,,&,&&& For Something To Happen, Far Away.  This &,&,,&&&,&
&&,,&&&,,& Is  Signaled  By Red  Or  Green  Lights. &&&,&,,&&&
