Looks like those wayside horns I questioned about a few weeks ago have just gone into service:

The horns were put into service on Monday, January 21, 2019, at the Cooper Street crossing, located between Cherry Street and South Colony Street in Meriden. In the coming weeks, wayside horns will be installed at the Pent Highway railroad crossing, located between North Plains Industrial Road and North Colony Road in Wallingford. CTDOT plans to continue the installation of wayside horns at grade crossings along the Hartford Line Rail to reduce noise.
Also, more browsing on the ConnDOT site reveals some upcoming "north end" construction:
Windsor - Temporary High Level Platform - Scope Code "F" ($2.5-5,000,000) - Advertising date 8/14/2019
Windsor Locks station - Facility Construction - Scope Code "M" ($40-60,000,000) - Advertising date 12/11/2019
Odd that they're spending that kind of money for a temporary high level platform, given that the eventual plan is to move the "station" south of the grade crossing and build a parking garage. Then again, maybe this is just a temporary solution, construct high level platforms on either side of the tracks and use the grade crossing as the crossing point, a la New London. As for Windsor Locks, that's a lot of cash for a station, which leads me to believe they may be relocating it to the original site north of "downtown" adjacent to the historic station. That site would need improvements from the ground up (parking), not to mention high level platforms and an up & over. The existing South Main St. site would need those improvements as well, but there's already some existing infrastructure to work with (some, but not much). Pros and cons with both sites. Any thoughts on which one they're going with?
