Late on Wednesday evening they opened up one set of the tracks but when the water main first broke it was at about the worst possible time, about 5:00 p.m., the start of the rush hour in Elgin. It shut down the Metra service.
Crews have been working all night to repair the break which happened just underneath the tracks. Fortunately, they were able to isolate the location early on so most residents never even noticed a change in water pressure.
"It was minimal. But by and large it was just a minimal impact," said Sue Olafson, spokesperson, city of Elgin.
The library closed due to the break. In the meantime, Metra says they expect to be back to full service on Thursday morning. City officials say they believe the water main break was caused by the big fluctuations in temperature from well below freezing to adjust above freezing for a short time on Wednesday.
