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

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