### Response Structure

```json
{
  "svcResL": [{
    "res": {
      "outConL": [{
        "date": "20260109",
        "dur": "025200",
        "chg": 0,
        "dep": {
          "dTimeS": "075700",
          "dPltfS": {"txt": "8A-B"}
        },
        "arr": {
          "aTimeS": "104900",
          "aPltfS": {"txt": "7"}
        },
        "secL": [{
          "type": "JNY",
          "jny": {
            "prodX": 0,
            "dirTxt": "Salzburg Hbf",
            "stopL": [...]
          }
        }]
      }],
      "common": {
        "locL": [...],
        "prodL": [...]
      }
    }
  }]
}
```

### Key Connection Fields

| Field | Description |
|-------|-------------|
| `dur` | Duration (HHMMSS) |
| `chg` | Number of changes |
| `dTimeS` | Scheduled departure |
| `dTimeR` | Real-time departure (if available) |
| `aTimeS` | Scheduled arrival |
| `aTimeR` | Real-time arrival (if available) |
| `dPltfS.txt` | Departure platform |
| `aPltfS.txt` | Arrival platform |
| `secL` | Journey sections (legs) |
| `secL[].jny.prodX` | Index into `common.prodL[]` for train name |

### Understanding prodX (Product Index)

**Important:** The `prodX` field in journey sections is an index into the `common.prodL[]` array, NOT the train name itself. To get the actual train name (e.g., "S7", "RJX 662"), you must look up `common.prodL[prodX].name`.

### Extracting Trip Summaries with jq

The raw TripSearch response is very verbose. Use this jq filter to extract a concise summary with resolved train names:

```bash
curl -s -X POST "https://fahrplan.oebb.at/bin/mgate.exe" \
  -H "Content-Type: application/json" \
  -d '{ ... }' | jq '
    .svcResL[0].res as $r |
    $r.common.prodL as $prods |
    [$r.outConL[] | {
      dep: .dep.dTimeS,
      arr: .arr.aTimeS,
      depPlatform: .dep.dPltfS.txt,
      arrPlatform: .arr.aPltfS.txt,
      dur: .dur,
      chg: .chg,
      legs: [.secL[] | select(.type == "JNY") | {
        train: $prods[.jny.prodX].name,
        dir: .jny.dirTxt,
        dep: .dep.dTimeS,
        arr: .arr.aTimeS,
        depPlatform: .dep.dPltfS.txt,
        arrPlatform: .arr.aPltfS.txt
      }]
    }]'
```

Example output:
```json
[
  {
    "dep": "213900",
    "arr": "221100",
    "depPlatform": "1",
    "arrPlatform": "3A-B",
    "dur": "003200",
    "chg": 0,
    "legs": [{"train": "S 7", "dir": "Flughafen Wien Bahnhof", "dep": "213900", "arr": "221100", ...}]
  }
]
```
