Read Json into AWS Lambda

Hi,

I have the following Json I'm trying to loop through:

{"codea": "23DWDQW","request_time": "2018-01-05T16:44:24Z","lookingup": {"497": [{"mode": "transit","line": "497","aimed_time": "16:45"
			},
			{"mode": "transit","line": "497","aimed_time": "16:45"
			}
		],"T1": [{"mode": "transit","line": "T1","aimed_time": "15:45"
			},
			{"mode": "transit","line": "T1","aimed_time": "15:45"
			}
		],"324": [{"mode": "transit","line": "324","aimed_time": "16:45"
			},
			{"mode": "transit","line": "324","aimed_time": "16:45"
			},
			{"mode": "transit","line": "324","aimed_time": "16:53"
			}
		]
	}
}

After pulling in the json from an external source I'm doing the following:

JObject busData;

busData = JObject.Parse(busContents);


// Tranverse to the "departures" token
JToken buses = busData.SelectToken("departures");

string busNumber;

foreach(JToken bus in buses.Children()) {

    // Get the Bus Number
    var busProperty = bus as JProperty;
    busNumber = busProperty.Name;

    Console.WriteLine("Bus Number: " + busNumber);

}

The problem I'm having is getting to the data underneath "497", "T1" and "324"... IE the "mode", "line" and "aimed_time" elements. Mainly because "497", "T1" and "324" can have different values each and every time I call the service.

Can anyone point me in the right direction?

Thanks James
