Looking on the Steam Railroading Institute's facebook page it looks like they will be holding Train Expo 2014 on June 20-22nd, 2014. They do not have much information on it yet but it looks like they will have trains, plans, and cars all featured.
I doubt it will be as big as Trainfestival 2009 but I wonder what locomotives will be making the trip. Maybe the 261 this time since she was int he middle of her rebuild in 2009. Maybe even the 765 will head back up north if she isn't to busy with the NS trips.
I think we should plan a forum get together during the weekend.
