Late last week I asked the question of whether we have enough trains. The post has resulted in a lot of discussion however some of the answers I received from Auckland Transport left me asking more questions. In particular
CAF has committed to supplying 46 EMUs for weekday operations. That number is sufficient for 12 of the 34 train sets required to operate the timetable to be doubled as 6-car trains.
So I sought some clarification around why only supply of 46 EMUs. AT have now have now provided that clarification confirming that the 46 was just to implement the services we have now and an additional six sets will be available for service once the roll-out has been completed.
The 46 sets is what CAF has confirmed they can supply to daily service as at 20 July. This does not include two additional EMUs that are held on standby ready to inject into service operations to smooth service recovery following disruption. A further three EMUs are not available as they are waiting for replacement ETCS equipment which has long lead times. These are expected to be released for service over the next few weeks. Three EMUs are “maintenance spares” which allow CAF to take the trains out of service for lengthy periods for major maintenance.
Capacity will be increased from the three trains currently out of service plus the three to be delivered next week. Once the accelerated delivery schedule is complete and all 57 EMUs have been accepted into service, up to six existing 3-carriage trains could be increased to 6-carriage trains (based on the current timetable).
I guess only time will tell if the extra six trains will be enough to cover the capacity constraints at the peak and shoulder peak periods.
Note: the comments of first post contained a lot of discussion around buying extra carriages or bringing back the old diesels. There is no need to rehash those arguments again.
