     But what ScotRail has now is a superb train that is fit for purpose. Turbostars were OK, certainly one of the best of the late 1990s glut of new designs. But were they really a good travel experience for 180 miles from Glasgow to Inverness? No, they were not (and I speak from experience). These HSTs offer a much better train for such a journey.

• acceptable, suitable
• up to standard
