MER Clinic: Evolution of an Operating Scheme

This clinic looks at how the Pennsylvania Southern and its operating scheme have evolved over the past 35 years. Any large layout grows with time to its current form and this layout is no exception. While the layout has moved twice, it has been in its present location for most of its existence. Those moves offered opportunities for development. Industrial growth over the years also led to the need for more cars, more trains to handle them, and more and different staging methods for those trains. As the crews improved their operating skills and as technology improved the methods of dispatching the railroad have also changed. All of these subjects will be discussed in this clinic.
