All I do is look at things un-scientific. Have to ask the customers.
In Connecticut one saw customers vanish. Many places the customers still exist. Scientific ? The cost to service them ? Most all Guilford's lines saw everything reduce to 10 mph ? I heard Guilford never lost a penny as to overall profits for owners. No maintenance = 10 mph = abandonment Satisfied Customers ? I recall one of last freight runs to Torrington Ct. The cars derailed when trying to put them on a siding.
Pick up new customers ? I think Connecticut is way behind as to even weight limits. Bridge north of Hartford ? Un-Scientific...look at size of freight cars modern times ?
Kind of curious about the new Berkshire Eastern I think it is. Don't think a website yet. I think they operate Hartford/Waterbury Ct. One thing is an ancient tunnel in Terryville. Track now at 10 mph ? The lonely trash train would keep on derailing and scared neighboring towns.

An oddity if one believes such but that tunnel has gone down as haunted for many many decades. Same reports. Dead workman I guess. Even the last video an odd sound there ? Never seen anything strange but if I did would be freaked out. For some reason humans have reported this stuff over the centuries.
