important tri-lamp headlight arrangement ("ditch lights") and reflector strips similar to those commonly found on highway tractor-trailers. Additionally, the measurements were based on accidents at grade-crossings, which are very low numbers overall to begin with. A grade-crossing that had two accidents during the comparison years, when contrasted with only one accident during the control period, would statistically yield a high percentage-wise improvement in safety, when in reality, it was the difference in only one accident for that grade-crossing.

the owners of the tracks must work together to ensure all federal regulations are being met. Quiet zones require improvements which would include installing standard or conventional automatic warning devices such as gates with lights if not already installed. Medians must be installed at the railroad crossings to ensure vehicles do not proceed into the opposite lane to go around the gates. Once all safety measures are completed train whistles will be silenced at the railroad crossings.

182:. This susceptibility is exacerbated by a train's enormous weight and inertia, which make it difficult to quickly stop when encountering an obstacle. Hence a means of warning others of the approach of a train from a distance is necessary. As train whistles are inexpensive compared to other warning devices, the use of loud and distinct whistles became the preferred solution for railway operators.

A well known commercially made chime was Hancock Inspirator Company's three-note step top. These found use on almost every American railroad. Some railroads copied these also, examples being found on the old

Many locomotive operators would have their own style of blowing the whistle, and it was often apparent who was operating the locomotive by the sound. Modern locomotives often make use of a push button switch to operate the air horn, eliminating any possibility of altering the horn's volume or pitch.

Train whistles are used to communicate with other railroad workers on a train or in the yard. Specific combinations of long and short whistles have specific meanings. They are used to pass instructions, as a safety signal, and to warn of impending movements of a train. Despite the advent of modern

The most popular
American chime train whistle was the three-note version. These were either commercially made (Crosby, Lunkenheimer, Star Brass, Hancock Inspirator Co. among others) or shop-made by the railroads themselves. Some famous and very melodious shop-made train whistles were Pennsy's

Another very popular
American train whistle was, again, a Nathan product. This was a five-note whistle, with a much shorter bell, and therefore, much higher in pitch. This whistle produced a bright G-major 6th chord (GBDEG) and, again, was heavily imitated, copies being made by many different

Conversely, there are those who do not object to the train whistle, as they believe it provides an important safety feature. Some people even like the sound of the whistle, as it calls to mind a nostalgic era, as with the riverboats and their steam whistles and
