Export railroad line with stations

Hello I am wishing to extract a railroad line with all the stations that this line crosses, ignoring if the stations are no longer in use and I wish to omit the level crossings. How do I do this? I have been trying for some days to extract the data precisely and I am not succeeding. Can someone help me?

My query:
[out:json];
(
nwr"name"=“Ferrocarril Mitre: Córdoba → Retiro”;
nwr"name"=“Ferrocarril Mitre: Retiro → Córdoba”;
);
// print results
