774 or Miss Lorraine Diner is a historic dining car located at 560 Mineral Springs Avenue (Rhode Island Route 15) in Pawtucket, Rhode Island, although much of the diner's existence has been in Connecticut.

This is a Worcester Streamliner dining car built in 1941 by the Worcester Lunch Car Company, and was located at 357 Asylum Avenue in Hartford, Connecticut across from the Hotel Bond.

[2] In 1956, the diner was auctioned off and moved to Kensington, Connecticut, where it remained inoperative for a decade.

[5] Discovered in a field in Middletown as part of another failed restoration attempt, it was later sold to another diner enthusiast named Jonathan Savage, who then moved it to Pawtucket at the Lorraine Mills Textile Manufacturing Complex along RI 15, where it remained dormant for more than nine years before opening on January 28, 2020.
