Yes, ScotRail have got a few of them now, seem to be in quite regular service.
Mostly still using the old coaches, with slam doors, though they are working on refurbishing them. They have provided instructions on how to open the doors.
Quite comfortable anyway, and more space than the 170s. Though not sure about the bike spaces, think most of them are in the guards van, so you have to run to one end of the train to get it in or out.
