Almeida was driving a flatbed work car at the time. A movable work platform was not retracted when the car started to move.
The projecting platform struck a bundle of cables on the wall, and then hit the wall of an electrical room in the tunnel.
The impact lifted the platform from its moorings until it struck the tunnel, forcing the unit backwards to where Almeida was stationed. He was struck and killed. Several other members of the 11-man crew were seriously injured.
The TTC pleaded guilty yesterday before Mr. Justice Robert Bigelow to a charge of failing to take every reasonable precaution for the protection of the worker.
