The 13th Annual Danbury Railway Days are this weekend.  The event features free train rides and a chance to operate a vintage locomotive. The educational activities start at 10am Saturday, noon on Sunday, ending both days at 5pm.  Train rides will beheld hourly.  Admission to the museum is $12 for ages 3 and up, free for current or retired railroad employees showing proper identification. The train will stop at the old New Haven RR turntable, built circa 1914 and listed on the National Register of Historic Places, where visitors will detrain and hear a discussion about the use and history of the only power-operated turntable in Connecticut, currently undergoing a significant restoration.
