But the TMC says otherwise. Spokesperson Harry Holmes says the concern is damage over time to pipelines running under the light rail track.
"These lines are full of high pressue steam and the chill water that supplies the air conditioning for the hospitals and that's where the patients are. It could, over time, that could be a real problems."
Holmes says the suit does not seek damages, but rather wants Metro to monitor the leakage in the TMC and establish a plan to remedy the situation.
