This chestnut of regular maintenance for the 22Ks seems to come up a lot in terms of justifying some of the crazier-looking rostering decisions like 29Ks to Sligo or 22Ks to M3 Parkway. How often do these units need servicing?
If the need for serving is such a problem, it would seem to be a bit silly to have the maintenance located so far out of the way of the regular routes of so many of the trains so that they have to be shuttled 50 or 60k from a terminus in order to receive regular maintenance.
