Peter - the C/K Sets run about as 4-car sets, made up of two of the pairs I mentioned in my post above. There is one 2-car C Set (C5) that lost the other two cars to fire a couple of years ago. This runs around as C-T-C-T-T-C where C is a Control Motor and T is a trailer car.
There are four 2-car K-Sets in operation in the Newcastle suburban area, where the trailer car also has a cab, to reduce the need for a four car set. In this case the trailer car is reclassified as "D" (Driver Control Trailer). As the cab is at the no2 end, it is not under the pantograph, rather it is at the opposite end of the car.

The car in the foreground is the Driver Trailer (note the lack of a destination board), and features the pantograph, but no motors. The second car is the Control Motor, which has all the motors (and a desto). This is one of the four Newcastle based 2-car K-Sets.

In both of these shots, I am standing at the no2 end of the trailer car, looking towards the front of the train. The area where the cab would be on the 2-car K-Set is a passenger area (longer than at the no1 end of the trailer/motor cars). Then you have the pantograph at the no1 end of the car, with a shorter vestibule area. Then you have the motor car, with the cab at the extreme far away end of the image.

(I do hope that link works)
That's a C-Set.
Sadly, I've not got many good photos of suburban trains, as normally when I see them I am working, so I don't bother taking photos of them when I'm not working, but they are all here:

Now, if Davido plans on making a "Freight Australia" skin for his NTAFs, that I can be of service with, as I took about a thousand photos of the various types of NTAF wagons on a recent jaunt to Canberra!
