Jerry, great to read that Lamy's is serving food again. Massachusetts's loss is Michigan's gain. The diner was built in 1946 and is a semi-streamliner Worcester Lunch Car model just like the Rosebud pictured in my post. So, absolutely, there's a railroad influence there. Do I remember correctly that the museum also has an original (or reproduction?) lunch wagon of the type that eventually gave rise to the architectural form?
