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

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