I started a new project this week. I was having some trouble with long wheel based locos on the S turn leading in to the Janesville viaduct. So I decided to move the bridge and eliminate the tunnel while in the process. The trains will have a much straighter run crossing the bridge which will relieve stress on the car couplers allowing for longer maybe 100 car trains. Plans for a second curved wooded bridge just down rails from the Janesville viaduct are now being considered.
