Any major railroad today offers a rich set of modeling challenges. We are working with Norfolk Southern to develop and implement systems for real-time and tactical planning of its locomotive fleet. This work is part of a larger effort to reorganize the flow of information within the railroad.
Above, we are looking at the flows of locomotives over the network, colored by the t ype of power. To the left, we are drilling into a single yard, at a point in time, looking at the formation of individual consists (usually two to four locomotives required to pull a single train) that may be assigned to each outbound train.
