rxr, This is the LORAM "rail grinding train" RG-15. They went via GRS to Danville Jct.,in Auburn,Maine,then onto the SLR where they did their grinding in "selected spots" in Maine,N.H.Vt. and Quebec on the St. & Lawrence Atlantic(Quebec). They returned Monday,did a little bit more grinding about 60-70 miles out of Auburn,then returned the same way vis Guilford. (no grinding on Guilford!).When the train(or whatever they call it correctly) is "working" it is an awesome spectacle!!! especially at night! I was hoping that it would grind at night through some "rich,YUPPIE,towns!!!!! The" beautiful folks" wouldve thought the end of world was near! Bud
