Hello,

Hoping some members here can review data (especially numbers) I've collated from various online sources for an academic paper on rail procurement trends in NSW between 2010 and 2020.
I'm counting individual items of rolling stock for heavy rail (individual carriages - not sets) but for light rail vehicles the sets are articulated (permanently made up of individual carriages), I'm classifying these light rail vehicles as a set as its unlikely they will be be broken up into carriages like you might see for heavy rail trains passing thru a workshop.
Some of the numbers don't add up notably row 1 and 3, Sydney Trains A & B sets, Wikipedia says for 'A' sets 626 cars (carriages) I calculate 624, and for the 'B' sets Wikipedia says 192, I calculate 208
I understand the  'A' Sets were procured in the dying days of the ALP Kenneally Government (Transport Minister John Robertson)? while everything else was procured through the LNP.

Thank you

There was a 4 car test train for the A sets of which 2 carriages have been used on the set damaged at Richmond. There are actually 26 sets and not 24 sets of the newer B series which is where wikipedia gets muddled up. There will eventually be 328 B set carriages.

Contracts often have spare carriages built into the contract, hence carriage totals may not be in multiples of 4 or 8.

Thanks for the numbers.

With regards to numbers Wikipedia seems not to be clear.....

A sets 78 sets consisting of  8 cars per set = 624 cars
B Sets 26 sets consisting of  8 cars per set = 208 cars

https://en.wikipedia.org/wiki/Sydney_Trains_A_%26_B_sets

Just to be clear, so for the B sets, the final number will be 328 cars instead of 208? I have adjusted B sets on the table in red for 328

Anyone spot any of numbers for the other classes not adding up (such as the A sets procured under the dying days of the ALP?), or any additional NSW Government procured passenger rolling stock classes I have missed?

Regards

The four car test train was stripped for spares and stored at Cardiff.
It was realised that the driving trailers were intended as spares and these were stored inside.
The power car shells were scrapped.
Only one of these was used in the set damaged at Richmond and the other is still spare.

The intention was that the power cars of the four car set would be rebuilt and used in a set but new cars were built instead.
So that adds two cars to the total built (if not purchased).

The two eight car sets used for testing were returned to China.
In theory, set A1 was returned, although it may have been a new set.
Set A2 was damaged during its return to China and a new set A80 was built to replace it.

So although only 626 cars were purchased either 10 additional cars were built or 18 additional cars were built.

But the contract was for 626.

Between B1 and B2 series there will be 41 sets

Thanks for the numbers.

Thanks, just to confirm
B sets
41 sets x 8 cars = 328 cars?
A sets  
78 sets x 8 cars = 624 cars.

A sets  
78 sets x 8 cars = 624 cars.

I also forgot to include the Alstom Metropolis TS sets. For these I tally
22 sets x 6 cars = 132 cars delivered
23 sets x 6 cars = 138 cars to be delivered.
