Description

Returns a distance, fare information, and estimated travel time between any two stations, including those on different lines. Omit both parameters to retrieve data for all stations.

Response Elements

Element Description
StationToStationInfos Array containing station to station information (StationToStationInfo).
CompositeMiles Distance in miles from the source to destination station.
DestinationStation Destination station code. Use this value in other rail-related APIs to retrieve data about a station.
RailFare Structure containing fare information.
RailTime Estimated travel time (schedule time) in minutes between the source and destination station. This is not correlated to minutes (Min) in Real-Time Rail Predictions.
SourceStation Origin station code. Use this value in other rail-related APIs to retrieve data about a station.
OffPeakTime Fare during off-peak times (times other than the ones described below).
PeakTime Fare during peak times (weekdays from opening to 9:30 AM and 3-7 PM, and weekends from midnight to closing).
SeniorDisabled Reduced fare for senior citizens or people with disabilities.
