National Archives Record Group 227 Records of the office of Scientific Research and Development | National Archives would be a good place to start looking for information about Project 10. I've included links here to several series in RG 227 that contain information on the Raytheon Company:
- Correspondence, 1941-1945 https://catalog.archives.gov/id/606877
- Project Administration Records, 1944-1945 https://catalog.archives.gov/id/894515
- Minutes of the Coordination Committee, 1941-1945 https://catalog.archives.gov/id/606688
For questions about these records, you can email the National Archives at Boston: firstname.lastname@example.org
Good luck with your search!

Are you looking for information on the train crash as well? There is an excellent guide to National Archives Records Relating to North American Railroads at - Select List of Publications: Reference Information Papers | National Archives Scroll down to reference information paper 91.
The Department of Transportation also has a portal with information on historical train accidents at DOT Online Database.
Finally, train accidents often result in court cases that are filled with detailed information, especially if there were fatalities or substantial damage. Federal Court Cases for North Dakota up to World War II are generally at the National Archives at Kansas City. If you are interested in pursuing the court case aspect, please contact the National Archives at Kansas City at email@example.com with information on the train company and anything you know about that particular train. The case probably would have been filed in one of the U.S. District Courts in North Dakota, but knowing more about where the line started and ended may help if it ended up in another court. Jurisdiction is sometimes decided based on where the accident took place and sometimes where the railroad company was based.
Good luck with your research!
