Thursday afternoon, there was a geyser on Spectrum Drive in North Austin...a big water main break right next to the Metro Rail line.
John Julitz with Cap Metro says the water did some damage to the tracks.
"That water is impacting the ballast, the rock that supports the stability of the tracks. You can see on the other side some of the rock has started to wash away. That is certainly going to present a safety issue," Julitz said.
He says until Cap Metro crews can strengthen the tracks, Metro Rail passengers are being put on buses instead.
