RAILS                   
                                          
                                          
  
                                          
  
                                          
                                          
 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.            
                                          
 THERE WILL  BE  TREES ON THE SIDE OF THE 
 RAILS, BUT NOT TOO CLOSE, OR  THEY  WILL 
 BE  CUT  DOWN  BY THE RAILWAY  JANITORS. 
 THERE  WILL  BE  PLAINS,  AND  BODIES OF 
                  WATER.                  
                                          
 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 
          DIFFERENT SPEED LIMITS.         
                                          
 SOMETIMES, TRAINS HAVE  TO STOP AND WAIT 
 FOR SOMETHING TO HAPPEN,  FAR AWAY. THIS 
 IS  SIGNALED  BY  RED OR  GREEN  LIGHTS. 
                                          
                                  
                                          
 MANY  PEOPLE  FOLLOW THE RAILS BY  FOOT. 
 OFTEN  THIS  PROVES  TO BE  THE  SHORTER 
 PATH BETWEEN  TWO  POINTS.  HOWEVER THIS 
 IS  FROWNED  UPON,  AND   VERY  IMPOLITE 
         TOWARD THE TRAIN DRIVERS!
