This week’s subzero temperatures and extreme wind chills have prompted numerous high-profile suspensions of service and closures.

Begin with the South Shore commuter line, which suspended service on Wednesday and today, after a test train early Wednesday morning “encountered significant overhead wire problems” related to the cold.

Regular service is currently expected to resume on Friday, Feb. 1, with westbound Train 102.

The U.S. Postal Service suspended service throughout most of the state today, “to ensure the safety and well-being of our employees.”

All post office retail operations remained open, however.

“We apologize for any inconvenience this weather related service disruption has caused,” said USPS District Manager Todd Hawkins, Greater Indiana District. “The safety and well-being of our employees is of paramount concern to the Postal Service.”

All Westchester Public Library locations closed at 5 p.m. Tuesday.

They were scheduled to re-open at 1 p.m. today.

Due to the cold, Republic Services canceled trash collection both on Wednesday and today, Chesterton Street Commissioner John Schnadenberg told the Chesterton Tribune this morning.

Wednesday’s route will not be collected until next Wednesday, Feb. 6. Chesterton residents who can’t wait until Wednesday, Feb. 6, and have no room in their can may bring their garbage to the Street Department, 1490 Broadway.

Meanwhile, today’s route will be collected on Friday, Feb. 1. Friday’s route will be collected on Saturday, Feb. 2.

The National Weather Service was saying this morning that the wind chill warning which has been in effect this week was scheduled to expire at 12 p.m today.
