Grace said Allen's friend made it to safety however Allen was struck as he tried to get out.
"He was looking for another, perhaps slightly easier place to exit from, and that's how he ended up on the lines when the train came through."
Grace said it appeared the pair had spent early Friday evening drinking alcohol at the builder's Hamilton home before heading to a few bars in town.
They decided to leave town about 4.30am when the fateful accident occurred.
"We're not concerned it was anything other than a tragic accident and there's no criminal investigation being conducted."
Allen's death had been referred to the coroner.
A death notice states Allen was a father of one. He will be farewelled in the city on Wednesday.
