6.8.2 Trains and Other Vehicles That Reverse Direction Since trains frequently stop at a destination to complete a trip, then reverse direction to begin a new trip, the same train consist may be used with a different order of component cars. Records in the Train_cars file representing individual train cars are associated with vehicles (train consists)

Similarly, if a transit agency standardly collects vehicle-level revenue, the agency could add a vehicle-based file that is similar to the Station_activities file to track revenue collected by each vehicle over exclusive time periods. 6.8.5 Boardings and Alighting Associated with a Specific Train Car As described in Section 3.2.1, some transit agencies may desire to track boardings by train car, in particular, to measure crowding along a rail platform.

The analysis produced from this specification should also clearly relay the sample period, the number of records sampled, and confidence levels. This will signal to those interpreting the data how reliable results are.

Alternatively, if a transit agency standardly collects trip-level revenue, they could add a field for aggregate revenue for each trip to the Trips_performed file, which would be populated directly from the Vendor Outputs. Similarly, if a transit agency standardly collects vehicle-level revenue, the agency could add a vehicle-based file that is similar to the Station_activities file to track revenue collected by each vehicle over exclusive time periods.
