1. Attention Steam Engine Folks! A more detailed look at the Colonel Ward Pumping Station's fabulous engine room.
   
   
2. New Contest. The “What the Heck Is It?” Contest in # 120 was not too bad! Even the one in # 121 is not too difficult, but the one planned for #121 is going to be a lot more difficult. Count on it! We'll keep you guessing and wondering this time, definitely!
   
   
3. What's the Horn Doctor up to now? As always, it's an interesting project, as this next Horn Doctor article demonstrates.
   
   
4. Whistle Engineering: Peter Ommundsen continues his research on all aspects of the steam whistle. For those of you who are contemplating building a real steam whistle, his articles are a definite must-read.
   
   
5. The Siren. We pay lots of attention to steam whistles and air horns in this magazine. But the mechanical siren is also a signal of interest. For the second time in 5 years, we'll look once again at mechanical sirens, particularly those for fire engine use, including the rare double-tone Federal 70 series, which sounds so bad that it is really great!
   
   

• One hundred years of Turbine Technology. Horn & Whistle visited a utility power plant which contains both a very early GE vertical turbine and the latest, high pressure modern turbines. Also look at an interesting Corliss engine powered pump at the same facility. H&W # 105)
  
  
• The Fabulous Sanfilippo Collection. This private museum outside of Chicago holds steam engines, a steam locomotive, a fantastic collection of old phonographs, steam whistles, early electrical machinery, and the world's largest theater pipe organ. We take you there in a two-part article.
  
  
• How Does a Railroad Air Horn Work? How do these relatively small signals manage to make so much noise? We look first at a generic air horn and then we examine the Nathan K Airchime in detail to see exactly what's inside and how it works.
  
  
• Where it all Began. Here's a brief look at the mighty pipe organ. It was from the pipe organ that our horns and whistles were developed. Read about the original collection of horns and whistles and see how the industrial revolution influenced pipe organ design, just as the pipe organ influenced the industrial revolution by giving it the steam whistles and air horns that we love.
  
  
• The Railroad Whistle's Companion. Learn about an interesting companion technology to the RR whistle. It was just as important if not even more important to the proper functioning of railroads as the train whistle. Some of the greatest mechanical engineering minds of the 19th century devoted their lives to this specialized technology. Read about it in Horn & Whistle issue #107.
  
  
• Recently, Horn & Whistle discovered a Corliss Engine and the original fire-tube boilers still installed in a municipal water works pumping station. Read about this rare find in H&W # 104.
  
  
• Restoring a Leslie SuperTyfon RR horn. HWEG member Mike Muha takes you through a step by-step restoration of the famous Leslie RR horns and also shows you how the unique Leslie diaphragm system works. H&W # 102)
  
  
• They still make Steam Whistles Today! Horn & Whistle visits the 100 year old factory of the Lunkenheimer Company in Cincinnati, OH. They are still making solid bronze steam whistles today and we'll show you how they do it in this wonderful manufacturing anachronism. And, you'll learn about the interesting market that still exists for steam (and compressed air) whistles.
  
  
• How Sirens Work. This three part series shows you how the major siren types operate and what is inside to make all that noise.
