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!
