Hagley Museum and library is in wilmington, de. If you type (hagley museum and library) you will get to there site. there is one more picture i will look for with a rail wagon and horse. I do not think there is any more pic arround that shows the rail cars. I found your post looking for building pic,s for someone i know that looks for old buttons in the hallow. I said this may help you with the trains. I have horses so i liked the 2 pictures. Jim
