"Okay, so I arrived at the train station on Monday morning just like we planned! But now I'm completely lost. I'm currently sitting in a taxi, and the driver is asking for directions. Help!"

Romance language speakers often use a single preposition (like en or à) for many of these situations, but English is pickier!

• We arrive at a specific building or location (like a station or airport), not in.

• Days of the week always take on (e.g., on Monday).

• For small vehicles where you cannot stand up and walk around, we use in (e.g., in a car, in a taxi). We use on for larger public transport (e.g., on a bus, on a train).
