Session 1: National Planning Models

Monday 8:00-9:30

Capacity Planning for the Indian Railways

Peter Cook, GIS Trans.
A large-scale decision support system was developed and used for capacity planning by the Indian Railways. The system, which features a GIS interface, estimates freight flows over a multi-modal network based upon modal performance capabilities.

Freight Demand Modelling in India

Carl Martland, MIT, Andreas Aeppli, A & L Associates, and Marc Warner.
A freight demand model based upon logistics costs was calibrated and validated using extensive data collected from a broad range of industries in India. The model was used to support capacity planning on the Indian Railways.

Strategies for Restructuring Railroad Networks

Daniel Roth, Mercer Management Consulting
An approach for identifying a profitable core network has been developed and applied in restructuring of rail freight networks in Europe and South Africa., The methodology builds up a traffic base beginning with flows that cover their variable costs, then adding traffic such that the resulting flows are able tog cover infrastructure costs of the required network.

Session 2: Issues in Line Performance Modelling

Monday 1:00-2:30 Panel Session. Co-Chairs: Carl Martland, MIT and Bill Vanmarter, CP Rail
This session will provide a forum for the discussion of modelling issues related to railroad line capacity and dispatching. The intent is to encourage a lively discussion involving all participants.


Line Capacity Optimization using the Branch & Bound Method

Erika Egyhaziova, Marc S. Meketon; MultiModal Applied Systems, Inc.
Intelligent railroad line capacity systems seek the best plan for meeting and passing trains on sidings and multiple tracks. The B&B method has been used in several commercial systems to develop the meet/pass plans. We overview the basics of this method, using simple examples for illustration purposes.
