Moe was allergic to shellfish, so substitutes were made out of sugar for him to eat in the drawing room scene.

Actor Bobby Burns and actress Hilda Title are called by their real names as they are boarding the train.
A near-verbatim remake of the 1932 Hal Roach short "Show Business," which starred Zasu Pitts and Thelma Todd, and featured Bobby Burns in a similar role. That short was directed by Jules White.
The train's route wends through western cattle country, a Hollywood movie star is aboard and fresh Dungeness crab is on the menu, so it's a safe bet that the train is the Chief, a passenger train that ran from Chicago to Los Angeles (the more famous Super Chief didn't start running till 1937, the year after this film was released).
