Try this..

try {

                jobj_trouve_train = new JSONObject(reponse_trouve_train);

                JSONObject jsonobj = jobj_trouve_train.getJSONObject("trains");
                JSONArray jsonobj1 = jsonobj.getJSONArray("train");

          for(int i = 0;i< jsonobj1.length();i++){
                JSONObject jsonj = jsonobj1.getJSONObject(i);

                System.out.println("@id "+jsonj.getString("@id"));
                //   Same for remaining all 
                }

            } catch (JSONException e) {
                // TODO Auto-generated catch block                  

                   e.printStackTrace();
        }

You can use the Gson library developed by Google to parse Json into objects. The reference is here: https://code.google.com/p/google-gson/ And, a sample example is here: JSON Parsing with GSON

JSONArray jasonArray = new JSONArray(result.getProperty("trains").toString());

for (int i = 0; i < jasonArray.length(); i++) {

JSONObject jsonObj = jasonArray.optJSONObject(i);
trainObject = new JSONObject(jsonObj.optString("train").toString());
int id = trainObject.optInt("id");

and so on..

}

public Object void toObject(String jsonMsg) throws JSONException {
    JSONObject trains= (JSONObject) new JSONTokener(jsonMsg).nextValue();
    if(trains.has("trains")){
               JSONArray train = (JSONArray) new JSONTokener(object.getString("train")).nextValue();
                for (int t = 0; t < jsonArray.length(); t++) {
                   String temp = jsonArray.getJSONObject(t).toString();
                   JSONObject object = (JSONObject) new JSONTokener(temp).nextValue();
                   if(object.has("@id"))
                      object.getString("@id");
                   // now similar procedure of reading
                   // read values and save it in an "object"
    }       
    return savedObject;
}

-- tested, i have tried to modify code to match your JSON data. complete the rest.
