50-Word Abstract -In recent months the integrative role of passenger rail in national transport has become obvious.  However, previous funding issues and current manufacturing leads prevent quick capacity increases.  Through an IP approach, this research aims to tailor train consists to demand in order to allow car reassignment to more crowded trains.

 

Cons

Existing Consist counts for all Northeast Services (Corridor, Inland, Keystone, & Tidewater) across October 2005, and as proposed by the model.

  

198

Unused and Used seats for Train #198 across October 2005.

 
 

LDF

Counts of each Peak LDF (Load Factor, or % Utilization at peak load) for existing and model results for October 2005.

 

Ongoing work: Refine mathematical model, and draft paper for publication.
