Key takeaways

  • Klæburuten belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Klæburuten to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Klæburuten from memory before moving on to harder problems.

Reference excerpt

Klæburuten AS was bus company based in Trondheim, Norway. It operated local buses within Klæbu Municipality, regional buses from there to Trondheim and the airport coach service from Trondheim to Trondheim Airport, Værnes. The company was founded as Krokum Bilruter as a sole propriotorship by Arnt Krokum in 1923, when he started a bus route from Klæbu to Trondheim. The company was reorganized and took the name Klæburuten in 1948. Its main depot at Sorgenfri opened in 1954. Between 1950 and 1974, Klæburuten also operated city buses in the Tiller neighborhood, before these were sold to Trondheim Trafikkselskap. The airport coach began in the late 1940s, and ran to Værnes from 1952. Klæburuten also operated a fleet of tour buses. The company remained family owned until it was sold to Nettbuss in 2010, and merged into Nettbuss Trøndelag on 1 January 2011.

History The company in question was not the first bus operator in Klæbu. That was done by Klaus Brøttem and Niels Høiset, who started a bus service from Heimdal Station to the ferry traffic on Selbusjøen at Brøttem, who operated the route from 1914 to 1916. Ricard Schei started it up again in 1919, and then sold the operation to Viljes Bilruter, and started operating it the full distance to Trondheim.

The bus service between the village of Klæbu and Trondheim was started by Arnt Krokum (1873–1934). He bought a Ford truck with wooden benches and space for 13 passengers. From 1923 he operated the route three times per week, under the name Krokum Bilruter. At the onset, the company was a sole proprietorship and based in Klæbu. Already the following year the Ford was replaced by a Dodge truck, which was rebuilt as a bus. It was substantially more comfortable, featuring leather seats and curtains. From 1925 the service increased to a daily trip, and then to twice daily from 1927. This led to the need of a second vehicle, and Krokum bought a Kissel, the first of his vehicles to have passenger seats facing forwards. By 1930 the buses were obsolete and worn out, and Krokum bought a new Reo bus for 17 thousand kroner. He was quite happy with the brand, and bought another Reo-bus for 13 thousand in 1932. The company's first garage and workshop was built on the farm of the first driver, at Sanda. A larger facility was then built at Lysklettflåtten, with a garage for multiple buses and a gas pump. Most repairs were done by the drivers at the garage. Arnt Krokum died in 1934, aged 61. The farm was taken over by his oldest son, Karl (b. 1903), while his youngest son Olav (1915–60) took over the bus company, effective in May 1935. He bought a third Reo bus in 1935, and the following year started a new route, Eklesbakken–Bratsberg and to Espåsen at Jonsvannet twice daily. This led to a fourth bus, from International, for 14 thousand kroner. A particularity at the time was that the company in Klæbu operated different routes during summer and winter. The snow and ice made certain road unreliable, and so several routes were cut short for the winter schedule. Krokum took over the route from Brøttem to Heimdal and Trondheim in 1940.

During the 1940s, the Second World War created a shortage of many products, including spare parts of not least fuel. Wood gas generators were installed on the buses to keep them going. Many of them were already in need of renewal, but it was difficult to order new vehicles, and Krokum bought two well-used buses to keep the operations flowing, a Hasselmann and an Opel Blitz.

Krokum merged his bus operations with the operations of two trucking companies, those of Ole Grav and Ingvald Aune, who operated milk- and cargo routes between Klæbu and Trondheim, and had thus secured all the scheduled routes within and from and to Klæbu. The company was reorganized as a limited company in 1948 and named Klæburuten AS. The same year the company started renting garage space from Autobuss in Elgeseter gate in Trondheim. Maintenance was moved to the city, where better access to spare parts made the work easier. Most of the buses were still overnighted in Klæbu.

Klæburuten started with airport coach service in the late 1940s. The first was with Norwegian Air Lines, which operated seaplanes out of Trondheim Airport, Hommelvik. They merged to form Scandinavian Airlines System (SAS) and moved their operations to Trondheim Airport, Værnes in 1952. Klæburuten received a fixed contract with SAS and bought a used Scania-Vabis B62 from them for the route. Klæburuten also operated the airpor coach service for Braathens SAFE. They initially operated from 1952 out of the closer Trondheim Airport, Lade, but moved their services to Værnes in 1956. Klæburuten would continue operating an airport coach service to Værnes for the rest of its operational history.

Klæburuten received a concession to operate the "ring route" in Tiller from 1950. The same year also saw the first international bus tour charter. This would over the years become an increasingly important business area for Klæburuten. By 1966, Klæburuten was operating five routes within the new, merged Trondheim Municipality, which included Tiller, but not Klæbu. These were from Trondheim to Klæbu (27 km/50 min), to Ler/Brøttem (36 km/75 min), to Bratsberg (19 km/40 min), to Tiller (22 km/50 min) and to Nedre Lerfoss/Hagen (24 km/55 min). At peak rush hours this meant the company operated twelve hourly services across Elgeseter Bridge into Trondheim, and three during off-peak hours. All the buses terminated at the bus station at Leütenhaven.

The company opened a new, main facilty and head office at Sorgenfri in Trondheim in 1954, then at Holtermannsvegen 63, today Tempeveien 17–19. This included offices, workshop, garage and a gas station. Olav died in 1960, aged only 45, and ownership and the position as managing director passed to his wife, Margrethe Krokum (nee Raaen).

For scheduled bus traffic in Trondheim, the company had 60 thousand revenue passengers in 1955, 450 thousand in 1965 and 1.24 million in 1972. By then it had six percent of the bus and tram traffic within Trondheim. In total, the company had a revenue of 5.1 million kroner, it had 32 buses and 50 employees that year.

Worked examples

Example 1 — a first encounter with Klæburuten

Start with the simplest possible case. Write down what Klæburuten claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Klæburuten before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Klæburuten ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Klæburuten

In research
Klæburuten appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Klæburuten in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Klæburuten is common in secondary-school and first-year university syllabi. It links to neighbouring topics Airport bus services, Bus companies of Trøndelag, Companies based in Trondheim, so understanding it makes those chapters shorter.
In everyday life
Look for Klæburuten outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
