How is that progress swapping speed for comfort ? Is the carriage layout similar a mix of twin seats in facing in both directions and groups of four with tables ? Has the legroom decreased [I am 6 ft 3 and have issues with some rolling stock but the mainline LNER carriages and Virgin before them had ample leg room] ? Is it the seating construction which is the issue, particularly on a long journey where it would possibly be uncomfortable to sit for long periods ? Thanks for any information Terry.
