What we need is allowing a buffer time between services so if the proceeding train is late the next train at Bidston or Wrexham can leave on or nearly on time. It takes regularly over an hour to run the full length of line, so you can't run an hourly service with jyst 2 trains. In theory a buffier at each end could occur with a 45min service and 4 trans. However, I believe 3 have been allocated from Dec 8th.. if it is true just one 230 and 2 x 197 that is shocking they can't still get 2 x 230 running out of 5 at the same time for some reason. The other issue is why the 230 that leaves Birkenhead North as Empty Coaching Stock, does not seem to have a buffer time if late leaving Birkenhead or is late running. This results in the 1st 230 not leaving on time, or is it delayed as staff are not available. You regularly see the 1st 230 of day running late, with a subsequent return service cancelled later in the day
As for cruddiness, that is not fair, its a much nicer passenger experience that a noisy 150.
