&,,,&,&&&, Have To Follow A Set Path.  This Path Is ,,,&,&&,,&
,&,,&&&,,& Called A  "Railway", Which  Is Comprised ,,,&&&,&,&

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

&,&&,,&&&, To Be Interpreted By The Train  Drivers. ,&&&,&&,,&
