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!
