STUDIES IN RAILROAD OPERATIONS AND ECONOMICS. VOLUME 3. DETERMINANTS OF LINE HAUL RELIABILITY

The authors look in detail at the variance in arrival time and its components for a total of 1197 trains operating over three different runs (of a single railroad) varying from 150 to 270 miles in length. Their data showed standard deviations of arrival times which typically ranged from 1 to 3-1/2 hours for trains operating on a half dozen different schedules. More important, the analysis of their data showed that the variability in departure time, in running time (excluding stops and delays), and in intermediate yard time were the major contributors to arrival time variance. Standard deviations of departure times (from initial terminal) were on the order of 45 minutes to 1-1/2 hours, of running times from 45 minutes to 2-1/2 hours, and of intermediate yard times from 1/2 hour to 1 hour.
