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