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

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

&,&,&,&,,, For Something To Happen, Far  Away. This &,&,,,&&,,
&&&&&&&&,, Is  Signaled  By  Red  Or Green  Lights. ,&&&,,&,&,
