And of course the other issue is that for quite a while during the run up to the service being cut to hourly, many of the trains were subject to "planned cancellations" the night before (maybe as many as 25% if I remember correctly), apparently due to driver shortages (not related to overtime bans etc.). I'd be surprised if they've resolved these issues during the reduced service period, so expect we'll go back to the same erratic service, and with less doubling up of units due to the more frequent service the experience overall may not be much of an improvement; specific services may well be more overcrowded than with the hourly service.
