The welded rail gang is working south, and as of today at 4PM,they are about 1/3 mile north of route 20 crossing in Northboro,ma.They should be working at route 20 area on Sunday.I spoke to workers 2 weeks ago and they said they started at 3AM, I am not sure if they still start that early.They work 8 10 hour days and than have 6 days offTHEY work Monday to Monday,and they should be off this Tuesday to Sunday.He was From Tennessee and had a 13 hour drive home.Where they are working Sunday is a great location to see them work. NORTHBORO has an apple fest going on today and Sunday right near the route 20 crossing.
