Travel-hacking-toolkit scandinavia-transit
Search trains, buses, and ferries across Norway (Entur), Sweden (ResRobot), and Denmark (Rejseplanen) for intra-Scandinavia travel planning. Use when planning ground transport between cities within Scandinavia. Triggers on "train", "bus", "ferry", "Vy", "SJ", "DSB", "Oslo to Bergen", "Stockholm to", "Copenhagen to", "Entur", "ResRobot", "Rejseplanen", "how to get between", "ground transport", "rail", or any intra-Scandinavia routing question.

Norway: Entur (Journey Planner v3)
Open GraphQL API. No key needed (but a client name header is required). Covers ALL Norwegian transit: Vy trains, buses, ferries, trams, metro. 60+ operators.
Trip Search (Oslo to Bergen example)
curl -s -X POST "https://api.entur.io/journey-planner/v3/graphql" \ -H "Content-Type: application/json" \ -H "ET-Client-Name: $ENTUR_CLIENT_NAME" \ -d '{"query": "{ trip(from: {place: \"NSR:StopPlace:59872\"}, to: {place: \"NSR:StopPlace:548\"}, numTripPatterns: 5) { tripPatterns { startTime duration legs { mode expectedStartTime expectedEndTime fromPlace { name } toPlace { name } line { publicCode name authority { name } } } } } }"}' | jq '.data.trip.tripPatterns[] | {start: .startTime, duration_min: (.duration / 60), legs: [.legs[] | {mode: .mode, from: .fromPlace.name, to: .toPlace.name, line: .line.publicCode, operator: .line.authority.name, depart: .expectedStartTime, arrive: .expectedEndTime}]}'
Find Stop IDs
Stop IDs use the format
NSR:StopPlace:XXXXX. Find them via the Geocoder:
curl -s "https://api.entur.io/geocoder/v1/autocomplete?text=Oslo%20S&size=3" \ -H "ET-Client-Name: $ENTUR_CLIENT_NAME" | jq '[.features[] | {name: .properties.name, id: .properties.id, type: .properties.layer}]'
Key Stop IDs
| City | Stop ID | Name |
|---|---|---|
| Oslo S | NSR:StopPlace:59872 | Oslo S |
| Bergen | NSR:StopPlace:548 | Bergen stasjon |
| Stavanger | NSR:StopPlace:4130 | Stavanger |
| Trondheim | NSR:StopPlace:41742 | Trondheim S |
| Bodo | NSR:StopPlace:49484 | Bodo stasjon |
Use the Geocoder to find any stop. Works for airports, ferry terminals, bus stops too.
Departure Board
curl -s -X POST "https://api.entur.io/journey-planner/v3/graphql" \ -H "Content-Type: application/json" \ -H "ET-Client-Name: $ENTUR_CLIENT_NAME" \ -d '{"query": "{ stopPlace(id: \"NSR:StopPlace:59872\") { name estimatedCalls(numberOfDepartures: 10) { expectedDepartureTime destinationDisplay { frontText } serviceJourney { journeyPattern { line { publicCode name transportMode } } } } } }"}' | jq '.data.stopPlace | {name: .name, departures: [.estimatedCalls[] | {time: .expectedDepartureTime, destination: .destinationDisplay.frontText, line: .serviceJourney.journeyPattern.line.publicCode, mode: .serviceJourney.journeyPattern.line.transportMode}]}'

Cross-Border Routes
| Route | Covered By | Notes |
|---|---|---|
| Oslo to Stockholm | Entur + ResRobot | SJ trains, ~6 hours |
| Malmö to Copenhagen | ResRobot + Rejseplanen | Øresund trains, 35 min |

When to Use
Load this skill when:
- Planning train/bus/ferry routes between Scandinavian cities
- Checking schedules and durations for ground transport
- Finding stop IDs for trip planning
- Comparing train vs flight for intra-Scandinavia legs
- Looking up Danish transit fares/zones
- Checking real-time disruptions (
)himsearch - Tracking live vehicle positions (
)journeypos
Do not:
- Use for booking (search/schedule only)
- Use for flights (use Seats.aero, SerpAPI, or Duffel)
- Expect pricing from Entur or ResRobot (only Rejseplanen has pricing)
Search Workflows
1. "How do I get from A to B?"
Step 1: Pick API by country (Norway=Entur, Sweden=ResRobot, Denmark=Rejseplanen, cross-border=both).
Step 2: Find stop IDs:
# Norway curl -s "https://api.entur.io/geocoder/v1/autocomplete?text=Flåm&size=3" \ -H "ET-Client-Name: $ENTUR_CLIENT_NAME" | jq '[.features[] | {name: .properties.name, id: .properties.id}]' # Sweden curl -s "https://api.resrobot.se/v2.1/location.name?input=Malmö&format=json&accessId=$RESROBOT_API_KEY" | jq '[.stopLocationOrCoordLocation[] | .StopLocation | {name: .name, id: .extId}] | .[0:5]' # Denmark curl -s "https://www.rejseplanen.dk/api/location.name?accessId=$REJSEPLANEN_API_KEY&input=Svendborg&format=json&type=S&lang=en" | jq '[.stopLocationOrCoordLocation[] | .StopLocation | {name: .name, id: .extId}] | .[0:5]'
Step 3: Trip search with
date and time. Step 4 (Denmark): Add tariff=1 for pricing.
2. "What trains leave from X?"
curl -s "https://www.rejseplanen.dk/api/departureBoard?accessId=$REJSEPLANEN_API_KEY&id=8600626&duration=120&products=31&format=json&lang=en" | jq '[.DepartureBoard.Departure[] | {time: .time, name: .name, direction: .direction, track: .track}]'
3. "What's near me?"
curl -s "https://www.rejseplanen.dk/api/location.nearbystops?accessId=$REJSEPLANEN_API_KEY&originCoordLat=55.6736&originCoordLong=12.5681&r=500&format=json&lang=en" | jq '[.stopLocationOrCoordLocation[] | .StopLocation | {name: .name, id: .extId, dist: .dist}]'
Or
nearbyDepartureBoard to skip stop lookup.
4. "What ferry to Ærø?"
curl -s "https://www.rejseplanen.dk/api/trip?accessId=$REJSEPLANEN_API_KEY&originId=100200261&destId=100200222&date=2026-08-28&time=08:00&format=json&lang=en" | jq '[.TripList.Trip[] | {legs: [.LegList.Leg[] | {name: .name, from: .Origin.name, to: .Destination.name, depTime: .Origin.time, arrTime: .Destination.time}]}] | .[0:5]'
5. "I know the train number."
trainSearch to find it, then journeyDetail with the ref for full stops.
6. "What can I reach in 2 hours?"
curl -s "https://www.rejseplanen.dk/api/reachability?accessId=$REJSEPLANEN_API_KEY&originId=8600626&duration=120&maxChange=2&format=json" | jq '.'
7. "Any disruptions?"
curl -s "https://www.rejseplanen.dk/api/himsearch?accessId=$REJSEPLANEN_API_KEY&format=json&lang=en" | jq '.'
8. Multi-country trips
Search from both ends. Øresund trains appear in both ResRobot and Rejseplanen.
Tips
- Always
. Alwaysformat=json
for Rejseplanen.lang=en - Use
(numeric) for queries, not the long HAFASextId
string.id - Check
/rtTime
for delays.rtDate
shows intermediate stops.passlist=1
for direct connections only.maxChange=0- Page with
/numF
ornumB
scroll tokens.context - Product bitmask is additive. Omit for all types.
