The conceptual engineering, which is summarized in this report, is based on existing track and train count characteristics and the National Railroad Passenger Corporation’s (Amtrak) anticipated station stops and schedule. The feasibility of providing passenger rail service on the Meridian – Fort Worth corridor (see Figure 1-1) or along a portion of it has been previously studied. Several prior reports and state rail plans, summarized in this report, have identified the need to evaluate this feasibility. Figure 1-1: Project Corridor between Fort Worth, Texas and Meridian, Mississippi Methodology For the purposes of this study, potential infrastructure improvements are limited to siding installations and extensions within the corridor. The methodology for identifying infrastructure improvements is dependent on the available data for each segment of existing track. The following methodology represents two separate approaches for identifying possible infrastructure improvements within the project corridor. 3 Fort Worth, TX to Dallas, TX: 1. High-level review of passenger rail service within the Trinity Railway Express TRE corridor –Review the current TRE commuter train schedules, current Amtrak Texas Eagle passenger train schedules, and the potential Amtrak passenger rail schedule to identify possible train meets within the corridor. Dallas, TX to Meridian, MS: 2. Compare existing Amtrak corridors and their characteristics –A multi-stage approach to identify potential passing siding locations for this corridor segment includes: a. Determine project corridor characteristics between stations on the Amtrak route. b. Identify existing Amtrak corridors located within or near the project corridor. c. Review lengths and spacing of siding and double track locations, type of signalization and maximum allowable train speeds on the existing Amtrak corridors. d. Review existing freight and passenger train volumes on the existing Amtrak corridors. e. Review On-Time Performance (OTP) of selected existing Amtrak service. f. Identify and compare variables (indicators) on infrastructure, train volumes and OTP between the selected Amtrak corridors and the project corridor between station limits. g. Determine potential passing siding infrastructure improvements based on results from the comparison of indicators. Improvements To identify passing siding improvements within the corridor, the data was reviewed and compared between corridor segments and indicators. These indicators include the infrastructure, operations, and OTP data. A spreadsheet-based model was created and run for the potential Amtrak schedule for the corridor length from Fort Worth, TX to Meridian, MS to validate Amtrak’s schedule from the evaluation that Amtrak conducted (using Alternative 3). The Fort Worth, TX to Dallas, TX segment was evaluated separately from the other potential passenger rail corridors since it is the only segment from the project corridor that currently has commuter service. Given the elevated number of commuter trains running in this segment, a high-level schedule review was conducted to evaluate the impacts of the anticipated passenger rail schedule provided by Amtrak. 4 To complete the evaluation, the Dallas, TX to Meridian, MS segment was divided into the following sub-segments: . Dallas, TX to Marshall, TX; . Marshall, TX to Shreveport, LA; . Shreveport, LA to Vicksburg, MS; and . Vicksburg, MS to Meridian, MS. The indicators described within Section 5 of this report were compared between the selected existing Amtrak routes and the Dallas, TX to Meridian, MS study segments. These indicators included: . OTP, . existing passing sidings, . percentage of double track, . freight and passenger train counts, and; . corridor capacity. The comparisons were conducted using simple regression analysis, with graphs to visualize the association between indicators and the calculation of the R2 coefficient to understand the strength of the relationship between these indicators. The observed regression with the strongest association between indicators and the highest R2 value was between the total number of daily trains and percentage of double track for those corridors with an OTP equal or greater than 80%, as seen in Figure 1-2.
