I have some links here that might be useful.
This one is to a campaign community created set (not created by me) for a Cthulhu adventure set in a coastal town - https://syrinscape.com/account/campaigns/5812-6550a38604/
This one is for all of the particularly spooky/fear-inducing sets between both the Fantasy and Sci-Fi players (which includes some Cthulhu-specific ones) - https://syrinscape.com/account/campaigns/6403-b68aa67011/
The Sea Monster set in the Sci-Fi player does have sounds of a metal ship in rough waters, without any specifically ultra-modern sounds of a newer engine, if that is needed.
Now, as Syrinscape doesn’t currently have old train sounds, old car sounds, or steam ship sounds, I had to turn to another source, one of my favorites outside of Syrinscape, Ambient Mixer.
This is a to a link for a search for “1920” - http://www.ambient-mixer.com/s/1920 It includes train, city, jazz club, and office sounds.
This one is for “orient express” - http://www.ambient-mixer.com/s/orient+express which includes several people’s variations.
This one is for “speakeasy” - http://www.ambient-mixer.com/s/speakeasy with many choices.
This is one for “jazz” - http://www.ambient-mixer.com/s/jazz Some might be more modern (Syrinscape does have a Music - Jazz soundset, but it’s a bit more modern as well) but some may be up your alley.
While Ambient Mixer doesn’t have Syrinscape’s versatility, it can help fill in the gaps not currently covered.

It would be souping-up or souped-up.
