Its interesting to look at Buffalo NY on Google maps. You can see the scars in the land of many fallen flags. With only Conrail at one time consolidation was a must. Present day is Buffalo still healthy for freight traffic? Or is it simply a place the railroads travel through to get somewhere else?
Also brings in mind the next question...you look across in Canada at some of the rail lines that connected with the US routes...they are all mostly abandoned or (around Niagra) still used, but jointed and weed covered. Why are the lines in Canada so poorly maintained?
