UK railway data extracted from publicly available datasets (see Rail Delivery Group page). It works as a good dataset for learning how Cypher's quantified path patterns work.
Run the Cypher in cypher/import.cypher against your Neo4j instance using Browser (you will need to remove the :auto commands if you want to run in cypher-shell). Note that the node and relationship counts will exceed the Aura free tier allowances.
Try it out with a query like this one:
MATCH (dmk:Station {name: 'Denmark Hill'})<-[:CALLS_AT]-(l1a:CallingPoint)
(()-[:NEXT]->(n)
WHERE NOT EXISTS { (n)-[:CALLS_AT]->(:Station:LondonGroup) })+
(l1b)-[:CALLS_AT]->(x:Station)<-[:CALLS_AT]-(l2a:CallingPoint)
(()-[:NEXT]->(m)
WHERE NOT EXISTS { (m)-[:CALLS_AT]->(:Station:LondonGroup) })+
(l2b)-[:CALLS_AT]->(gtw:Station {name: 'Gatwick Airport'})
MATCH (l1a)-[:HAS]->(s1:Stop)-[:NEXT]->+(s2)<-[:HAS]-(l1b)
WHERE time('09:30') < s1.departs < time('10:00')
MATCH (l2a)-[:HAS]->(s3:Stop)-[:NEXT]->+(s4)<-[:HAS]-(l2b)
WHERE s2.arrives < s3.departs < s2.arrives + duration('PT15M')
RETURN s1.departs AS leg1Departs, s2.arrives AS leg1Arrives, x.name AS changeAt,
s3.departs AS leg2Departs, s4.arrives AS leg2Arrive,
duration.between(s1.departs, s4.arrives).minutes AS journeyTime
ORDER BY leg2Arrive LIMIT 5All being well, it should return the following results:
╒═══════════╤═══════════╤══════════════════╤═══════════╤═══════════╤═══════════╕
│leg1Departs│leg1Arrives│changeAt │leg2Departs│leg2Arrive │journeyTime│
