Any sightings of 4021 and/or 4022?Which should be taken as a guarantee that all 22 units would not, under any circumstances, be delivered by the end of September - at least not September this year.
(I read somewhere not long ago that delivery of all 22 EMUs was scheduled to be completed by end of September.}
We wouldn't want Bombardier to slip up and do something inconsistent with the tradition established with every other one of their previous delivery schedules for the EMUs.
It's a pity that the government didn't demand the inclusion of a similar clause to the one which had Siemens building Deutsche Bahn an extra Velaro D high speed unit once the delay was longer than six months. We could have enough free A-City EMUs to run a high frequency service on the next Adelaide-Salisbury stage by now!
