Smalltalk in the large

Nice - I've found some infos on the "RUT-K" project on the Cincom blog. It's the train scheduling system for the German railway built with VisualWorks Smalltalk and Oracle. I worked in the project as a Smalltalk consultant and developer for 2 years and helped to bring it in shape. You can read more about it in the ESUG2004 Report.

It's another example of a successfull large software project realized in Smalltalk. Smalltalk drastically reduced the complexity. The picture shows a typical construction window. The upper graphic pane shows the trains path and the lower graphic pane is used to find conflicts with other trains. Click on the image to enlarge.
