Methinks that was when Maine Eastern had to "set out" some of the covered gons,with "rubble" from Maine Yankee,when they were returned,still loaded,from the disposal site. Caused quite a stir,when the railroad used the Cathance siding)an old MEC passing track,off Rt. 24 in Topsham.
Don't know if the railroad left them there,to keep em' "outta sight.outta mind",as compared to Brunswick yard,or even the start of the low road,by Rock Jct. off Federal St. They also use Bayside siding,in Woolwich,in back of the Taste of Maine resturant for this Woolwich residents complain a little,but the Cathance episode,brought in TV covverage,and Topsham checked things out with a Geiger Counter-NOTHING!!!
But,then you never know. Stone blocks,that were the only part of Rowe Atomic Plant,that was salvaged,and used in readsboro Vt.(remember the Hoosac Tunnel & Wilmington &(VT) RR?? Were just found to be slightly "hot" after about a decade there!!!
So,that was the "freight" movement that the photo showed! Bud
