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

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

,&,,&,&,,&       The Way, There Is Information      &&&&&,&&&,
,&&,&&&&,& Scattered, Often  Put  On Top  Of Poles, &,,,,&&,,&
