Could 158s keep time, they are limited to 90mph, and their acceleration rate is pretty gutless over about 80mph
I'm not sure it ever was tightened to be fair, like you say, it was mostly 150's previously.
When I've travelled from Taunton to Newport on the GWR services (short HSTs then IETs), they've usually laid over at Temple Meads for 10 - 15 minutes. RTT suggests that that's normal off-peak, though there are shorter stops in the peak. Shortening that stop might produce conflicts elsewhere, but it does imply that they're not tightly timed.
