Forgive me for bumping a 5 year old thread:
I work for the Maine DOT and stumbled across this site about a year ago when we were doing work on the Sarah Long Bridge in Kittery/Portsmouth. In our attempt to build a new bridge, we had serious concerns regarding the location of this mysterous train engine, and how it may impact the construction of pier footings for the new bridge.
After scanning the bottom of the river with LiDAR, we have an extremely clear image and location of two train cars, as well as other features of the river bottom roughly 1/4 mile upstream and downstream from the bridge.
If anyone is still interested, I can provide both a wonderful image of the bottom of the river in this area, as well as pin point locations for the two rail cars.
I have absolutely zero diving experience (to be honest, the thought of being underwater for extended periods of time kind of frightens me), but I appreciate the opportunity to share some information with the diving community.
