I have found some old maps of the rail lines and yards in the metro Cleveland area. One map dates map back to 1934 http://www.railsandtrails.com/Maps/Cleveland/CleveMap-100a.jpg
No date on this map and no color http://www.railsandtrails.com/Maps/Cleveland/ClevelandRRMap-100.jpg

How do you start a locomotive with weak batteries? You jump it. Kind of like jump starting your car, but only with a lot more juice. This past Saturday, I got to help and see this happen to a Alco RS3 locomotive. This old lady did put out a lot of smoke at first. Then she started to do a slow chug. With each chug, more smoke would puff out. As the chug became quicker, more smoke came out. Soon, she was running on her own power and the smoke died down some. If you have a chance on November 25, come down and see her running. See the post below for details.
