Reply To: Putting on teffilin without saying shacharis?

Depending on one’s commute, it may make more sense to to briefly put on tefillin at the earliest time, say Shma, and then daven without being rushed on the train (works better on a long commuter or intercity train than on a crowded subway) ESPECIALLY IF THE ALTERNATIVE is to quickly daven before rushing out the door. It’s only a minhag, at best, to wear tefillin while davening but it is a halacha to daven with kavanah.
