## Quick Reports

### Verbindung A → B

```bash
curl -sf "https://efa.vrr.de/vrr/XML_TRIP_REQUEST2?outputFormat=rapidJSON&type_origin=stop&name_origin=ORIGIN&type_destination=stop&name_destination=DEST&useRealtime=1&itdTripDateTimeDepArr=dep" \
| jq -r '
  .journeys[:6][] |
  .legs[0] as $first | .legs[-1] as $last |
  ($first.origin.departureTimePlanned // "")[11:16] as $dep |
  ($first.origin.departureTimeEstimated // "")[11:16] as $dep_est |
  ($last.destination.arrivalTimePlanned // "")[11:16] as $arr |
  ($first.transportation.product.name // "") + " " + ($first.transportation.disassembledName // "") |
  ltrimstr(" ") as $line |
  ($first.origin.properties.platformName // "?") as $gl |
  (if $dep_est != "" and $dep_est != $dep then " (+" + (($dep_est[3:5] | tonumber) - ($dep[3:5] | tonumber) | tostring) + ")" else "" end) as $delay |
  "\($dep)\($delay) | Gl. \($gl) | \($line) → an \($arr)"
'
```

**Beispiel:** `name_origin=Dortmund%20Hbf&name_destination=Bochum%20Hbf`

**Output:**
```
11:45 (+1) | Gl. 16 | Regionalzug RE1 → an 11:54
11:53 | Gl. 7 | S-Bahn S1 → an 12:16
12:07 | Gl. 16 | Regionalzug RE6 → an 12:18
```

### Abfahrtstafel (nächste Abfahrten ab Haltestelle)

```bash
curl -sf "https://efa.vrr.de/vrr/XML_DM_REQUEST?outputFormat=rapidJSON&type_dm=stop&name_dm=HALTESTELLE&mode=direct&useRealtime=1" \
| jq -r '
  .stopEvents[:10][] |
  (.departureTimePlanned // "")[11:16] as $dep |
  (.departureTimeEstimated // "")[11:16] as $dep_est |
  (.transportation.disassembledName // .transportation.name // "?") as $line |
  (.transportation.destination.name // "?") as $dest |
  (.location.properties.platformName // "?") as $gl |
  (if $dep_est != "" and $dep_est != $dep then " (+" + (($dep_est[3:5] | tonumber) - ($dep[3:5] | tonumber) | tostring) + ")" else "" end) as $delay |
  "\($dep)\($delay) | Gl. \($gl) | \($line) → \($dest)"
'
```

**Beispiel:** `name_dm=Essen%20Hbf`

**Output:**
```
11:37 (+4) | Gl. 3 | 105 → Finefraustr.
11:38 (+3) | Gl. 1 | U11 → Gelsenkirchen
11:40 (+9) | Gl. 8 | RE2 → Osnabrück Hbf
```

### Haltestelle suchen

```bash
curl -sf "https://efa.vrr.de/vrr/XML_STOPFINDER_REQUEST?outputFormat=rapidJSON&type_sf=any&name_sf=SUCHBEGRIFF" \
| jq -r '.locations[:5][] | "\(.name) [\(.type)] id:\(.id)"'
```

**Beispiel:** `name_sf=Dortmund%20Signal`

**Output:**
