You can not set a null value in Firebase, since Firebase treats null as an instruction to delete the node. To quote the docs:

Passing null to set() will remove the data at the specified location.

Since your application most likely uses the null to signal some specific condition, you should substitute another value to signal that condition:

ref.child('trainName').set('<unnamed>');

Update

If you want to delete a node, you can do:

usersRef.child(key).remove();

See also the documentation for the Firebase delete function.

Is your question: "how do I delete a node using AngularFire?" That was not obvious to me from your question. – Frank van Puffelen Apr 22 '15 at 19:32
I just got to know from you that it cant be set to null... So wanna delete the record.... – Kiran Kumar Apr 22 '15 at 19:35
