Trains

Like most visitors to this forum, trains were a daily part of my life in Hammond. About the time that I was in the fourth grade, my family moved to 6123 Harrison. We lived two doors down from an EJ&E spur that served the nearby Rand-McNally plant, and three blocks from the Erie tracks. On nice days, my sisters and I walked to All Saints School. Waiting for trains was part of our lives early on, as we had to cross the Erie tracks at Highland and Sohl, and then the Nickel Plate tracks at Sohl and Fayette. But in cold or rainy weather, we got to take the bus to school. We got on the South Shore Line at Harrison and Conkey, but getting to All Saints required that we change buses in Downtown Hammond. Being the youngest of the troupe, I was content to wait for the next bus at our transfer point at Sibley and Hohman. But my sisters were often no so content, and we would walk the remaining three blocks to school. Walking to school from downtown required that we cross even more train tracks, first the Monon and then the Erie and Nickel Plate. We also walked past the Monon and Nickel Plate stations, where we witnessed the regular starting of the massive steam engines as they labored to pull their trains out of the stations. The Monon station was on State Street at Willow Court, and the Nickel Plate station was at the intersection of Sibley and Oakley. When I first got up close to those steam engines, their huge drive wheels - which were taller than me - were jaw-dropping, and the sound they made as the train pulled away was absolutely frightening. I only stood my ground because the adults around me went about their business. Now that I look back on it, I had the good fortune to witness a phenomenon that died when steam engines were retired from service - taking the slack out of the train. The steam-driven pistons that powered the drive wheels delivered torque in pulses. Each push of the piston rods moved the drive wheel forward a bit. As the repetition of pulses increased, the drive wheels rolled faster and faster. But there was a hitch, and it occurred when the engine began pulling away from the station. As a train approached a station and slowed to a stop, the cars lost the slack in the couplings and bumped into each other. As the train departed, the engine would move forward - until it took up the slack. At that point, the full weight of the cars held the engine back while the steam pistons were delivering full power to the drive wheels. The result was wheel slippage, accompanied by the most horrendous noise that I have ever heard. There is no way for me to do justice to the sound of steam engine wheel slippage, but I will try. When the engineer was ready to depart, he would transfer steam from the boiler to the pistons located on each side of the engine. As the pistons pushed the rods attached to the drive wheels, each push delivered a sound like "SHOOMPH." The initial SHOOMPH would move the drive wheels a few inches, to be followed by another SHOOMPH and more forward motion. But after about four or so slow and steady SHOOMPH'S, the slack was gone. The engine was now pulling the full weight of its cars. This meeting of the high-torque pistons and the full weight of the train caused wheel slippage. The force of the pistons against the high load made the wheels lose traction and spin for several revolutions. When that happened, the sound from the pistons went from a low and steady SHOOMPH to a rapid cacophony of sound magnitudes higher, "S, SH, SH, SHO, SHOO, SHOOM, SHOOMP, SHOOMPH," which took all of two seconds. Then the wheels would regain traction and the low and steady SHOOMPH would return, shortly to be disturbed by another round or two of hellacious wheel slippage. Thanks to a poster on a railroad history web site, I found a sound file of a steam engine that includes wheel slippage. Unfortunately, the engine is some distance away from where the sound was recorded. It is hard to hear the initial SHOOMPH'S, but you will hear the sounds of the wheel slippage as the train gains speed. You can find it at www.youtube.com/watch?v=vltKG9hIxw. 60
