My sons and I were walking on a railroad track about 45 miles south of Louisville, KY this past weekend and found the same kind of rock.  I believe that it is a piece of metallic slag from a smelting operation.  See this link for further info: http://en.allexperts.com/q/Geology-1359/2010/2/Shiny-silver-rock.htm

I live in Michigan and you can find these rocks just about everywhere along the railroad track. If we have the same type of rocks(darker silver color)

I'm almost 100% sure that these rocks are called Antimony there used to harden metals and are used in batteries so they are pretty common (depending on where you live) i live maybe a mile from a train track that heads down toward Detroit and they are common all along these tracks and im certain they use them to harden metals that are used in cars.

Expertise

I can answer any general geology question (rocks, minerals, stratigraphy, geomorphology etc.). My expertise is in the geology of the Michigan Basin, PreCambrian, Paleozoic and Recent. I can answer questions concerning mining and petroleum exploration and production and the laws concerning those activities. I can also answer questions concerning stratigraphy of the Michigan Basin. I will also answer questions about mineral and rock collecting in the Basin. I won`t be able to answer many specific questions on hydrology, geophysics or geochemistry. I may be able to answer very general questions in those venues.

Experience

I have been working for the State of Michigan for 36 years as a Geologist and a Resource Analyst. I have experience with Subsurface Geology and Petroleum Geology, mining in Michigan, and Sand Dune Mining and Protection issues.
