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

,,&&,,&,,& 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  Parts  Of  The  Railway  Have &,,,,&&&,,

&,,&&,,,,& Is  Signaled  By  Red  Or  Green Lights. &,&,,,,,&&
