Help: can't change file ownership

This is driving me crazy and I can't understand what I am doing wrong...

I'm running this command:

oli_g@server3:/home/oli_g/train
14:51:11 # chown cert train.prg
chown: changing ownership of 'train.prg': Operation not permitted

Permissions on the file are fully open
14:51:05 # ll
total 8
-rwxrwxrwx 1 oli_g cert 4313 Sep 28 14:50 train.prg

And so are permissions on the parent folder
14:53:34 # ll -d train
drwxrwxrwx 2 oli_g cert 23 Sep 28 14:51 train

It's a RedHat box and I don't have root access.

14:56:58 # cat /etc/redhat-release
Red Hat Enterprise Linux Server release 7.9 (Maipo)
