No difference.

The nuance between the two sentences is subtle but present: 1. "Are we going to get off the next stop?" - This phrasing suggests a future plan or intention. It's asking if, in the future, the action of getting off at the next stop is going to happen or if it's part of the plan. 2. "Are we getting off the next stop?" - This phrasing suggests a present decision or immediate future action. It's asking if the action of getting off at the next stop is currently under consideration or if it's going to happen in the near future. So, while both sentences essentially ask about the same action, the first one focuses on future intention or plan, while the second one focuses more on the immediate decision or action.

Both sentences convey a similar meaning, but there is a slight nuance in their structures: 1. "Are we going to get off the next station?" - This sentence implies a future action. It's asking about the intention or plan to get off at the next station. 2. "Are we getting off the next station?" - This sentence implies a more immediate or ongoing action. It suggests that getting off at the next station is already part of the plan or that the action is imminent.

I agree with Profe Jose. There’s really no difference in the way those sentences would be understood. There’s a potential that: Are we going to get off at the next stop? Might sound like you’re uncertain about how to get the final destination. It could imply something like “I’ve never been to this place before, is this the correct stop? Is this when we’re supposed to get off the train?” But, that interpretation would be more based off your tone than your words.

-No difference- We are going to get off the next stop - gerund used in the future tense. We are getting off the next stop- gerund used in the present tense referring to the future.
