I include this entry until more information known. I have seen various Trolley entries in relation to Westview Park. They built a special line to the Park. I as of now can not even find the location.

BELT LINE - This was a loop the trolleys ran between Derby and Ansonia. Starting from Derby's Main and Elizabeth Streets, it ran up Elizabeth Street to Atwater Avenue, crossing into Ansonia onto Clifton Avenue. From there it continued to Bridge Street, then turned south onto Main Street. From Ansonia's Main Street, it continued all the way to Derby, crossing at Derby Avenue. From Derby Avenue, it crossed the Naugatuck onto Main Street, Derby, at the DERBY JUNCTION. From there, it proceeded on Main Street, Derby, all the way to Elizabeth Street, making a complete loop. There were branches that were built over the years off the belt line. In Derby these branches included Shelton and HOUSATONIC AVENUE via Main Street, and to New Haven via New Haven Avenue. In Ansonia these branches included a spur to Scotland Street and Westview Park from Clifton Avenue and Bridge Street, via Lester, High, Franklin, and Jackson Streets and Wakelee Avenue, and a link to Seymour via North Main Street.

BIDDY LAMB'S POND (Ansonia) - Located in a natural hollow, and said to be fed by three underground streams, the pond was located on North State Street. Its size varied, depending upon the time of year. The pond was eliminated in the 1920s.
