What are the best games for this exact trope? (Other than Flower Princess Eluru which is also awesome)

Try your luck on game's page, as current one has become unneeded within hours - https://f95zone.to/threads/chikan-undercover-agent-rina-v0-07-trial-metamorphose.234500/
There was actually one game mentioned with female MC, if that what you looking for.
If you looking for games that have trains in general, just use chikan here or others porngames sites
