1. Steam Engine Folks! You're going to love this issue. I've been busy going around scouting for pumping station engines, and I have found several really impressive installations. I know I promised these articles before, but this last winter I decided not to go on any extensive drives, especially since several of the plants and things I want to feature are in parts of the USA where the weather is about as bad as it can possibly be. But winter is over now, finally, so in the new issue, if you like steam engines, you are going to find much of interest.
   
2. New Contest. The “What the Heck Is It?” Contest in # 124 was somewhat different. However, it's my goal to see if I can find a subject that absolutely none of you will guess. But the H&W readership is collectively very knowledgeable, very astute, and very up on all kinds of esoteric technology, and I have never yet stumped the entire group. But I shall try again this time.
   
3. What's the Horn Doctor up to now? Another excellent article by Ken Kanne, our horn editor whom you know better as the Horn Doctor, the guy who can repair virtually any damage to any horn, no matter how bad..
   
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. Electronic Fog Signals. Interest in this class of signal is quite low, according to our reader survey, although a few of you are interested. Last year I made a number of day trips to different lighthouse locations in Maine. Then I followed that up with some research. The common belief shared by many of us horn and whistle guys is that they are nothing but glorified loudspeakers. Well, there's a lot more to it than that. Hey, let's face it. Electronic signals don't compare with the mighty CC, F and F2T diaphones, but some of them are pretty impressive in their own right. We'll take a brief look at the new voice of the lighthouse and see what these look like and how they work. Some of them are surprisingly powerful.

• 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.
