This is the Mount Wood tunnel near Wheeling, WV from a couple of months ago. Out of all the tunnels I've been to, I'd say this one had the most incredible tunnels and having the tracks still intact and submerged made it extra cool. The tunnel was built for the Wheeling Bridge and Terminal Railway in 1888-89. It meets the Ohio River, where a bridge once stood that spanned the river over to Martins Ferry, Ohio. The tunnel is 1,200 feet long but has collapsed in the middle completely.
