One of many peoples favorite lines was the Central New England Railroad as most prefer to still call it. Most was abandoned around 1930 and tracks were sold as scrap to Japan in the mid-30's.
There was also a line to New Hartford.
There was also a line to Watertown.
There was the Shepaug Railroad from Danbury area to Litchfield which gave up the ghost approx. late 1940's.
The last image is the Ore Hill station prior to abandonment of the line. At one time Ore Hill was center of a massive 'Iron Furnace' industry. The prior image is the Twin Lakes station.
An update to above comments: That was the "Harrisburg Day Express". It ran for a few years in the 1890s. Route in Mass. was the Central Mass., or more accurately the B&M Southern Division at the time, Boston to Northampton, then over the New Haven Canal Line through Westfield and to the CNE main line in CT. There was some joint control over some of the participating railroads; the Reading was involved somehow. It was one of many Poughkeepsie Bridge services offered in and out of New England.
