68 5.1 Introduction This guidebook concludes with a discussion of recent and ongoing planning for the ChicagoSaint Louis high speed rail implementation on the UP and CN line. This line will host high speed trains in the near term, along with increasing amounts of freight and conventional passenger services.

Taking Shared-Use to the Next Level: Chicago–Saint Louis High Speed Rail 69 The outcome of that study was a judgment that such an infrastructure approach was too expensive and that efforts should instead focus on upgraded speeds and frequencies using existing, shared alignments with freight carriers. The 1994 IDOT Chicago-St.

70 Capacity Modeling Guidebook for Shared-Use Passenger and Freight Rail Operations 5.4 A Timely Example The study team believes the Chicago-Saint Louis project provides valuable insights for those considering major passenger rail corridor upgrades, on shared track, in other corridors. When completed it will be the only example of a freight carrier-dispatched and owned alignment with a high number freight trains as well as 110 passenger mph trains.

Taking Shared-Use to the Next Level: Chicago–Saint Louis High Speed Rail 73 the conclusion of a two-decade period of industry expansion where even basic track materials were often priced at a premium and in short supply. A UP modeling expert was dedicated, at IDOT expense, to work solely on the Saint Louis service alignment along with two external consultants approved jointly by UP and IDOT.

While a detailed description of the negotiations process is beyond the scope of this study, it may be noted that the areas of greatest challenge have proven to be: • Measurement of service performance.

76 Capacity Modeling Guidebook for Shared-Use Passenger and Freight Rail Operations Finally, it should be noted that a limited portion of 110 mph Amtrak service began in November 2012 over a 14-mile segment between Dwight and Pontiac. IDOT and Union Pacific are carefully monitoring train and signal performance as well as engineering maintenance issues associated with 110 mph operations as providing context for the large scale rollout of higher speeds in the next few years.
