Lee Yi-hsiang, 49, said he was "deeply remorseful" and wanted to give his "most sincere apologies".
His flatbed lorry was parked on an embankment but slipped down it, causing the train to derail on Friday near the city of Hualien.
At least 48 people were killed and more than 200 injured in the crash.
Lee was part of a team who regularly inspected Taiwan's mountainous eastern train line for landslides and other risks. He was also thought to the flatbed's operator.
He was questioned over the weekend by prosecutors and released on bail, but on Sunday he was taken back into custody because he was deemed a flight risk and had a previous conviction, Taiwanese media reported.
Reading a statement to news crews outside his house, Lee said he would co-operate with crash investigators, and "take the responsibility I should take". He was then taken away by police.
The eight-carriage train was travelling from the capital Taipei to Taitung when it hit the flatbed and crashed inside a tunnel north of Hualien.
The train was packed with people travelling to celebrate a long-weekend holiday, and many of the nearly 500 passengers on board may have been standing because the train was so full.
Some survivors lost their whole families, AFP reports. Taiwan declared three days of national mourning.
Crews are still slowly and carefully removing the train wreck from the tunnel. There are fears more bodies could be found.

CCTV footage examined
Investigators have been going through the train's recording devices and CCTV footage from the front carriage, the chairman of the Taiwan Transportation Safety Board told AFP.
"According to the testimonies by some passengers, they heard the horn being sounded and it's believed the train driver had spotted an object on the track," Hong Young said.
He added that the train driver, who was among those killed, would have struggled to avoid the crash.
"It's believed the train driver might have only had 10 seconds at most to react and there was not enough distance to emergency brake," he said.

There have been mounting questions over how full the train was, and why there were no barricades on that section of the track.
This led to Taiwan's transport minister, Lin Chia-lung, offering his resignation on Sunday. On Facebook, he wrote: "I should have accepted all the criticism over the past few days, but we have not done well enough."
The government has not accepted his resignation, however, and said he should stay in the position until the investigation was complete.
