Like many members of the railway engineering community, I don't have the opportunity to ride as many trains as I would like. While I certainly see trains while out on the property and ride the occasional inspection car, seeing the varied engineering details of modern railroading from the point of view of a passenger are fewer and farther between. Last month, I had the opportunity for some personal train travel that carried me to central New Jersey and New York City. For those out there who may not have the opportunity for recent passenger service exposures, I thought I'd share some of my observations based on that trip.
