Big Toot

The other day, an alert (and noise-sensitive) “06880” reader asked:

Do you have any idea how long the trains are going to blasting their horns through Westport? It started before we went away March 1st. I’m sure they must be getting a lot of complaints.

Though I live a couple of miles from the tracks, I’ve actually heard the horns myself. Well, maybe they’re car horns from drivers trying to navigate the increasingly chaotic Playhouse Square parking lot. Whatever.

I sounded out (ho ho) Aaron Donovan. He’s an MTA spokesman, and — because “06880” is “where Westport meets the world” — a 1994 Staples graduate.

He reported back:

This is a result of the Connecticut Department of Transportation’s long-term project to replace all the New Haven Line overhead wires, which were first installed in 1907. These original wires use antiquated “fixed termination” technology, which unfortunately allows the wires to sag ever so slightly during periods of high heat (it isn’t visible to the naked eye) or contract during periods of extreme cold, causing operations problems for trains. The DOT is updating the wires, more formally known as catenary, with a state-of-the-art “constant tension” system that will better accommodate the extreme temperature that can impact our region.

The good news is that this is the very last leg of the project. The DOT recently completed the section between Southport and Bridgeport, and are now turning attention to the section between Norwalk and Southport. In the current phase of the project, DOT’s contractors are out on the tracks digging holes to sink foundations for the gantries from which the new wire system will be suspended. For the safety of all personnel who are on or near the tracks, trains are required to sound their horns when approaching work zones.

The project is scheduled to be completed in September 2017.

Thanks, Aaron! That’s a lot more information than those signs that say “Good Service”!
