That particular section was the original first class when MML bought them in 2 car form. They had a lot of complains from people about the poor quality of the 1st class (particularly the 2+2 seating), aswell as general overcrowding and other issues. When the centre coach was added they had a proper 1st section with 2+1 seating and the old 1st in the ends was declassified, giving proper first class and extra standard class (infact a 3 car Turbostar has more standard class seating than a 4 car Meridien). Of cource, that bit was still nicer than the normal standard, not only with slightly better seats, but also being it's own compartment and the fact that people didn't tend to know it was declassified so didn't sit there. Bit like "premium economy" on longhaul flights, but without the premium. Not all Turbostars got an extra coach and those that didn't retained the old first class at the ends. When they transfered to Central, the end first class on the 2 car sets and the centre first class on the 3 cars was declassified. Sadly the quality of particularly the old 1st class behind the cabs has dropped a lot, with reclining mechanisms often broken (so they won't lock upright), the partition doors usually failed, and the general tiredness of the ex MML sets (which were introduced around this time 9 years ago, and are therefore at least a third of the way through their lives). I wouldn't be suprised if when Cross Country take over the Birmingham based Citylink routes from Central they don't use the 3 car ex MML Turbostars and bring back 1st class.
