A78 - Those vents are there to provide some air flow for the passengers in the upper deck, that is all.  The two different types is purely due to them being different series cars.  I think you will find that the vents in the "no air" photo still allow air in the upper deck of the carriage, they just don't appear to have large visible openings.  They are not there to cool any mechanical parts of the train.

R44 - Exactly what Seb said. His explanation was spot on.  That train would've been way late if they'd stuffed around looking for and R target plate, as it was that train was lucky to make it out on time.

Sandown - There are indeed the 2 car K's.  Technically they are Silver Sets, however they're are NOT of the S-Set family, in the fact they are air conditioned, and run their air and electrical systems slightly different.

A78 - Back when they did run 2 car S-Sets, they were considered "L-Sets" and back then an L-Set could have been a 2 or 3 car set.  I believe you are correct that there were some inconvenient failures of the 2 car L-Sets, that led the powers that be to make them 3 car sets for extra redundancy against failures, and also increase capacity.  Once all the control driver cars had been converted to trailers, the possibility of having 2 car L-Sets was gone, so L-Sets became 3 car sets as the norm.

Actually, originally 2-car sets were T sets, this changed with the introduction of Tangaras.

and back then an L-Set could have been a 2 or 3 car set.

Not really correct. 3 car sets are a fairly recent phenomena.

I believe you are correct that there were some inconvenient failures of the 2 car L-Sets, that led the powers that be to make them 3 car sets for extra redundancy against failures, and also increase capacity.

Almost correct. With a 2 car set, there is only one compressor to work the braking system. If that fails, then the braking system is screwed. That was the reason behind the decision to abandon 2 car sets using the standard cars.

Not sure about the 2 car K-sets though, do they have one or two compressors?

Thankyou for the apparent clarification, however I don't recall saying K sets were of the S-Set family. I was merely pointing out that there are Driving Trailers still around unlike your earlier statement to the contary.

The 2 car K sets have only 1 compressor. If it fails then its a dead duck.

They only have one Spring Park Brake too, takes about Sydney Terminal to Pennant Hillst to be able to smell the ratchet fully applied.

sandown - point taken. I misread the point of view where you were coming from. I posted after an hour ride home at 2am after too many runs through ecrl and somewhat stuffed.

- You sound like you speak from experience with regard to that ratchet brake at pennant hills...

I can verify that a ratchet brake applied from HMC, will cause class 4/5 skidded wheels before Cowan... the tell tale hint is the need to power into Mount Kuring-gai...

I got another question. It it's about timetable booklets the airport and east hills & south and Cumberland line ones

First off they both say effective October 2010 but then the south line one says updated November 2010 but still has the cityrail logo and a lesser updated map (can tell by Macarthur station having no whchr access icon)
Whereas the airport and east hills one was only upated in oct 2010 and is more updated than the south line one and the map has been updated

And your question isssss . . . ? ? ?

A78 - I'm afraid I failed to see a question in your post.  My guess is that you want to know why one time table was updated later, and yet one appears to remain unchanged, desspite them both being "Effective October 2010" and the one that says "Updated November 2010" appears to have older information than the one that doesn't say "updated".  The answer to that is probably that  the Airport/East Hills line timetable wasn't changed and therefore did not need to be updated, but as the stocks of them were used up and they re-printed them, the new ones will have the new logos and network maps.  I would suggest the South Line timetable is an older print.  It really depends where you get your timetable from.  I guarantee that if you ask for a Bankstown timetable from Central, and then ask for the same one at Hornsby, the timetable from Hornsby will be older than the one from Central.  Central would go thru their stocks of Banko timetables much quicker than Hornsby.

If my assumption/guess doesn't answer what you wanted to know, feel free to add a question...

Why is this still permitted? I know of railways where trains are prohibited from running if they have less than 2 compressors.

"Why is this still permitted? I know of railways where trains are prohibited from running if they have less than 2 compressors."
It' a numbers game - what are the chances of that happening? And if it does, it won't be too long before there is train behind it that will be able to couple up and give it an air feed and shift it to either a siding or maintenance yard. Also if you look where the 2 car K's are used you'll see that they are never too far from help. Apart from that, there's nothing else for them to use until other sets are freed up. Kinda hard to justify a 4 car service for a total of 13 people from Gosford to Hornsby at 1 am.

Seriously though, 13 people?

R44 - That 2 Car K-set is the last one out of newcastle of a night.  Occasionally one carriage is half full, but that is rare.

Also - despite my statement claiming it would be hard to justify using 4 cars for very few passengers, it appears the 2 car K-sets are to be replaced with 4 car OSCARs sooner rather than later... Including for that run describle above.

... Now back to R-Sets in off peak...

Back off topic.
2 car L sets were mainly unreliable due to the trailer having no batteries, this was the thing that stopped them in their tracks more than anything rather than losing the lone compressor as suggested.
All sets from K onwards have battery chargers and batteries in each and every car.
Another reason which killed the last 2 car L sets on the south coast was the inability to fit cab aircon to the trailer due to the full steel roof and no auxiliary power unit. It must have been cheaper to add second power car than pay drivers the old monetary allowance for no cab aircon.

In general R sets, and to a certain extent non air conditioned stock are not timetabled to operate in off peak and on weekends.

This is achievable in Sector 3, with no R sets tabled in the off peak and no non air conditioned sets tabled on the weekend, although quite often HMC send out the incorrect set types (I know there is a few from HMC on here and I'll accept that sometimes there is no choice but really it is too often). 

In Sector 1 there are no non air conditioned stock tabled on weekends, but MMC also quite regularly operate the wrong set type.

However in Sector 2 there are just not enough airconditioned stock to cover all required services.  The Waratahs will change that.  As for the R sets, there is an effort to keep them out of service in the off peak, but more importantly the R sets are placed where they are to position them for the peaks, so some off peak running is not possible to avoid.

As already noted the Sector 3 R sets have been replaced, as have some in Sector 2.  All that remain are 5 super-six (or Pocket rocket) R sets. Eventually there will be enough Waratahs to replace these as well.

Theres no R Sets left on sector 3 anyway.

How come there isn't any R Sets. there isn't any new trains there yet to replace the R sets so that means you have less trains
 
R44 Chief Commissioner

A78, read this carefully, and please DO NOT RESPOND

All Sector 3 R sets were transferred to sector 2.

Sector 2 then gave sector 3 S150 and S151.

Kaprende?
