"In the early 1990s, British Rail introduced the 182-strong Class 158 fleet, followed by the 22-strong Class 159s. These units heralded a new era in long-distance travel at the time, replacing 1950s-designed locomotive-hauled coaches on long secondary and inter-city routes

With all 204 units still in service today, this title aims to examine their varied operations, from Scotland to the south-west, from Wales to East Anglia, where they can still be found all across our rail network."
