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

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

,,&,,&&,,, Sometimes,  Trains Have To Stop And Wait &,&&&&&,,&
,&&,&,&,,, For Something To Happen, Far Away.  This &&,,,,&,&&
&,&&&&&,,& Is  Signaled  By  Red  Or Green  Lights. ,&,,,&&&,&
