"This train does not have a stop here!"

Translation: Acest tren nu are oprire aici!

[Mapka15]

My answer "Acest tren nu are o oprire aici" was counted wrong. But the correct answer ("Acest tren nu are oprire aici") by Duolingo is missing "o" (o oprire)... What is regular in Romanian?

I do not know how to explain this, but in this context it sounds more natural to drop the undefinite article "o". Romanian is very irregular compared to other languages.

”Acest tren nu o oprire aici” was given as one of two correct answers (multiple choice). Shouldn't there be an ”are” between ”nu” and ”o”?

Indeed, it would be missing the verb.

Would trenul acesta be correct, too?
