NYC through Central and Southern Indiana?

I’m wondering if anyone has any good sources of information on the NYC trackage and history through central and southern Indiana around the 1920’s through 1930’s. I’m especially interested in literature or photos of the line that ran though Greensburg, IN. And, Roger Hensley, if you read this don’t hesitate to contribute or email me!

I’m also trying to find some info reagrding a Milwaukee Road accident near Blackhawk or Lewis, IN that would have happened between 1935- 1950 (it’s a big window of time, I know) on the MILW line that ran on to Linton, IN

Any leads or info would be much appreciated!

Mike
