I agree on the calculation of the operating ratio, and I agree on how to calculate the average load factor for the system.  But I don't see the direct seat and passenger miles for individual trains on the routes shown in the Route Performance Report.  However, you can back into them, I think, but it does not give one the information necessary to calculate the load factors by segments.The ability to look at segments, which I presume Amtrak management can do, is important to see which segments are generating the revenue.  I ride the Eagle from Texas to Chicago and back three or four times a year.  The passenger load that I have observed south of St. Louis in the coaches is considerably lighter than the load between St. Louis and Chicago both ways.  The load in the sleeper, as expected, tends to be higher south of St. Louis.Average load factors are potentially deceiving. They don't indicate how well a train is performing on a segment, e.g. Dallas to Cleburne, Austin to San Antonio, etc., or on what days they have a relative heavy or light load.  Medians are usually more informative because they tend to dampen the variance around the mean by giving less emphasis to the highs and lows that can distort averages.  I have been tracking the on-time performance for trains 21, 22, 1, 2, 821, and 822 at key Texas stations since August 1, 2007.  In every instance, the median number of minutes the trains have been late is less than the average.Does anyone know the number of saleable seats, on average, in a Superliner coach and sleeping car?  Thanks.
