Beginning with Amtrak’s FY13 Monthly Performance Reports (MPR), which includes FY12 comparative data, an all-stations on-time performance report has been included together with the end-point performance report.  Now we can see how well the trains do on average at stations between the end-points.  The all-stations report appears to be the mean of an array of averages, which is not a very precise statistic, but it is interesting. In FY13 the end point on-time performance for the system was 82.3 per cent whilst the all-stations figure was 79.6 per cent.  In FY12 the comparative numbers were 83 and 80.1. For the Acela the median end-point on-time percentage for FY12 and FY13 was 87.5, and the all-stations number was 90.6.  The numbers for the Northeast regional trains were 85.4 and 84.  The results may suggest that the Acela had trouble with the last lap or two. The short distance trains had a median end-point percentage of 82.0 and an all-stations percentage of 84.2.  The best performing short distance trains were the Capitols, with a median end-point on-time performance record of 94.6 per cent and an all-stations on-time performance record of 95.7 per cent.  The worst performing train in this category was the Pere Marquette, which had a median end-point on-time performance percentage of 50.6 per cent and an all-stations median of 54.0 per cent. The long distance trains underperformed the system.  The median end-point on-time performance for them was 71.3 per cent, whilst the median all-stations on-time performance record was 54.7 per cent.  This suggests that the long distance trains improve their performance during the last several laps of their run, thanks in part to heavily padded schedules.  This is certainly the case for Number 21, which gets 3 hours and 25 minutes to run from Austin to San Antonio vs. 2.5 hours for its counterpart, Number 22, to get from San Antonio to Austin. At 88 per cent the City of New Orleans had the best median end-point on-time performance record, whilst the Crescent and Palmetto had the best all-stations records at 72.6 per cent.  The Cardinal was the worst performing long distance train, with a median end-point on-time performance record of 49.6 per cent and a median all-stations on-time performance records of 44.6 per cent. I excluded the Auto-Train from the analysis, inasmuch as it does not serve any intermediate stations, and is a different animal from the other long distance trains.  Also, there were several trains in the short distance and long distance categories that came within a hair of the best and worst performers.
