Cars On Line
Cars On Line is the average of the daily on-line inventory of freight cars. Articulated cars are counted as a single unit. Cars on private tracks (e.g., at a customer's facility) are counted on the last railroad on which they were located. Maintenance of way cars are excluded.
Trailer or Container for the purpose of these reports is calculated using the following method: Trailer represents a physical trailer permanently attached to the chassis or a container which continued to be attached to a chassis while being moved by Norfolk Southern. In this example, a container on a chassis represents one record similar to a trailer. Container represents only the container being moved by Norfolk Southern.
Train Speed
Train Speed measures the line-haul movement between terminals. The average speed is calculated by dividing train-miles by total hours operated, excluding yard and local trains, passenger trains, maintenance of way trains, and terminal time. System-wide average train speeds are given for the following train types:
- Intermodal
- Manifest
- Multilevel
- Coal Unit
- Grain Unit
- All trains
Terminal Dwell (Hours)
Terminal Dwell is the average time a car resides at the specified terminal location expressed in hours. The measurement begins with a customer release, received interchange, or train arrival event and ends with a customer placement (actual or constructive), delivered or offered in interchange, or train departure event. Cars that move through a terminal on a run-through train are excluded, as are stored, bad ordered, and maintenance of way cars.
