Incidents

Rail, bus, and elevator disruptions/outages.

JSON - Elevator/Escalator Outages

Description

Returns a list of reported elevator and escalator outages at a given station. Omit the StationCode parameter to return all reported outages.

Note that for stations with multiple platforms and therefore StationCodes (e.g.: Metro Center, L'Enfant Plaza, etc.), a distinct call is required for each StationCode.

Elevator and escalator outages are refreshed once every 20 to 30 seconds approximately.

Response Elements

Element Description
ElevatorIncidents Array containing elevator/escalator outage information (ElevatorIncident).
ElevatorIncident Elements
DateOutOfServ Date and time (Eastern Standard Time) unit was reported out of service. Will be in YYYY-MM-DDTHH:mm:ss format (e.g.: 2014-10-27T15:17:00).
DateUpdated Date and time (Eastern Standard Time) outage details was last updated. Will be in YYYY-MM-DDTHH:mm:ss format (e.g.: 2014-10-27T15:17:00).
DisplayOrder Deprecated.
EstimatedReturnToService Estimated date and time (Eastern Standard Time) by when unit is expected to return to normal service. May be NULL, otherwise will be in YYYY-MM-DDTHH:mm:ss format (e.g.: 2014-10-27T23:59:59).
LocationDescription Free-text description of the unit location within a station (e.g.: Escalator between mezzanine and platform).
StationCode Unit's station code. Use this value in other rail-related APIs to retrieve data about a station.
StationName Full station name, may include entrance information (e.g.: Metro Center, G and 11th St Entrance).
SymptomCode Deprecated.
SymptomDescription Description for why the unit is out of service or otherwise in reduced operation.
TimeOutOfService Deprecated. Use the time portion of the DateOutOfServ element.
UnitName Unique identifier for unit, by type (a single elevator and escalator may have the same UnitName, but no two elevators or two escalators will have the same UnitName).
UnitStatus Deprecated. If listed here, the unit is inoperational or otherwise impaired.
UnitType Type of unit. Will be ELEVATOR or ESCALATOR.
