This locomotive is housed in a small, glass enclosed shed located between Beach Blvd and Pablo Ave in Jacksonville Beach, FL.
The shed sits over part of the old Jacksonville & Atlantic Railroad grade built some time in the 1880s or early 1890s to run seventeen miles from South Jacksonville to Pablo, FL. The railroad was purchased by Henry Flagler in 1899 and became part of the Florida East Coast system. It may originally have been a narrow gauge line converted to standard after the purchase.
The shed housing #7 was built in 1996 and dedicated as "Pablo Station". I visited in early January, so the tender still sported a Christmas tree!
