Observations (Transperth, A & B series)

Looks like the last Joondalup/Mandurah line A set is gone as of today - so now exclusively run by 6 car B sets during the day on weekdays. The bus forum also reports that the remaining "short" off-peak services have been strengthened to 4 cars on the Fremantle-Midland and Thornlie lines, along with some but not all services on the Armadale line.

Presumably set 115 at least is in service now?

yep that's correct, B set 104 is the only set that hasn't entered service BET 6104 had to be sent back to Queensland for repair works, their is also another set off traffic for the B3 upgrade program, presumable once that work is complete the older B sets might be refurbished, the same with the A series one set off traffic for refurb works, their is only 2x 2car A sets left on Armadale during peak times and off peak and 2 3 car sets on Butler/Mandurah during peak.

Bs are running Midland-Freo tonight. (Presumably Claisebrook depot is offline due to the Armadale Line shutdown?)

^ And the Bs are running again this weekend.

Nice start to the year.

B sets were used on the Midland - Fremantle run for a few weekends recently.  Anyone know why?  Seems to have coincided with the Armadale line shut down but I'm trying to work out the link between the two scenarios.

As far as I know (and I'm open to correction) over the shutdown weekends, there was no access in and out of Claisebrook depot to get the A series out, so B series trains were substituted in their place.

A few A series cars were stored at Thornlie to keep the limited services on the Armadale line running.

Is that any different to the average weekend?

My observations for Sundays have usually been 2 car A sets on the express services (typically upgraded to 4 car sets if there are major events on) and 4 car As on the all stations runs.

Edit: from my subsequent observations it appears to be a regular occurrence during Sunday daytime AFL matches to release A sets for footy specials. Haven't seen it in use for Saturday matches (which finish after the timetabled frequency has reduced to every 30 minutes.)

Correct me if I'm wrong on a few things:

The A-series sets are approaching their 30 year design life and there are no proposals for life extension?

We now have all the B-series sets from the third order taking us to 116? (And to clarify - I think of the the third order as being for 22 sets - the 15 ordered in 2011 plus the two extensions of 2 and 5 sets whilst deliveries were in progress.)

The two older orders of B's should all have been upgraded to the newer standard by now?

The fourth order of of 10 sets is yet to make a delivery?

OK, now net me go look for another old thread that may be worth resurrecting.

A series are nearly 30 years old. Not sure about design life, but they are still being regularly overhauled at Claisebrook and there is no word on them being replaced.

B series upgrade to B3 standards almost complete. Set 78 is being done at the moment and set 79 is the last one to be done.

B series railcar BET6104 still away for repairs in Queensland, other than that, all railcars from the third order have been delivered and are in service.

No railcars from 4th order have arrived, nor are in the process of delivery at this time.

Thanks for the comprehensive reply Steve.

As for the 30 year design life figure I quoted, I took that from an engineering report on the A-series that I came across dated April 2015. It lists a few life extension options, the first being no extension – design life expiry 30 years. Then two options for “minor modifications” to extend life to 35 or 40 years, and two options for “re-engineering” both extending life to 50 years. The conclusions of the report didn’t seem to support the re-engineering options.

By comparison the Public Transport for Perth in 2031 draft report from mid 2011 refers to replacement of railcars (not referring to the A-series in particular) after 35 years of service (p23), but elsewhere it refers to "an operating life of up to 35 years before they need substantial refurbishment" (p31) at "75% of the replacement cost" (p32).

As an outside observer I'm guessing that the PTA would prefer to move on from the A-series as soon as possible, but may need to hang on a bit longer for the B's to start cascading down as the C-series is introduced.
