Nedenfor er utdrag av tekst fra beskrivelse av Hjuksebø-ulykken på norsk og engelsk Wikipedia. Det interessante er at den engelske teksten om denne hendelse er mye mer omfattende enn den norske. De er heller ikke helt enig om årsakssammenhengen. Siden jeg ikke vet helt nøyaktig hva som hendte har jeg ikke gjort noe forsøk på å korrigere noen av beskrivelsene. Dog er det imponerende at det står et så stort oppslag som det gjør om en snart 60 år gammel togulykke i Norge i engelskspråklig Wikipedia.

"Årsaken til ulykken var at det foregikk skifting på Hjuksebø stasjon. Skiftelokomotivet kjørte inntil en rekke godsvogner som i strid med forskriftene ikke var innbyrdes sammenkoblet. De ytterste vognene i rekken ble dermed gitt fart mot fallet. En av de løpske vognene var lastet med impregnerte telefonstolper, noe som gjorde at ødeleggelsene på det lettbygde motorvognsettet vognene kolliderte med ble spesielt store."

"Normally, the operation of preparing the freight train would wait until the passenger express train from Kristiansand had passed through Hjuksebø, but on this day the shunter at the station was informed that the express was a few minutes delayed. With this extra time, he decided that there was sufficient time to execute the turn-around operation now. The engine of train 5443 was detached from its carriages and pushed the freight cars ahead of it southwards with the intention of pulling them back in on track 3, ready for the return journey. Unfortunately, the four freight cars at the front were not attached to the rest of the train.
South of Hjuksebø, the line slopes downwards towards Holtsås station. The shunter made a desperate attempt to run and catch up with the runaway cars, hoping to jump on it and engage the emergency brake. The shunter was able at first to clamber onto one of the cars, but was blocked from getting to the front of the runaway cars where the crucial brake was located, so he was forced to jump off and try to run alongside it to reach the front. The breakaway cars were now speeding up and the shunter failed to make it. The engine which had pushed the cars followed, after the runaway, hooting a warning signal to warn trains ahead of the danger.
The station master at Hjuksebø realised the impending danger and called down to Holtsås hoping to stop the incoming passenger train no. 72. The call was too late, and the runaway freight cars and the train no. 72 collided at 10:50."
