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!
