Evening Ks
Spotting weekday evening peak K set services before the April timetable reshuffle
With the planned April timetable changes looming, which would see a large portion of the already dwindling K set services get replaced by the Waratahs, now was a great time to spot these silver trains before they're all gone.
As far as I am aware, there are currently no plans to retain any K sets for heritage purposes. In fact, in their 2019 report, Transport Heritage NSW (THNSW) recommended against preserving any C¹ or K sets.
Our THNSW Collections & Curatorial Committee has recommended no C or K sets be retained
However, a separate organisation, SETS, has preserved a C set train in the past, although it is non-operational and it is unclear when, or if it will ever return for heritage operations. Hopefully something similar could be done with K sets, but only time will tell.
About the K Sets
Built by Goninan & Co., the K sets are now the oldest train type currently in service in the suburban fleet following the recent retirement of the V sets.
Initial orders of Ks were retrofitted with air conditioning in the 90's, whilst later orders were built with AC. This is different from the older S sets, which never got air con installed.
Unlike the more modern trains in the fleet, the K sets also have open gangways, a slight safety hazard but providing a nice breeze when moving. They are the last in the working fleet to have a gangway design like this.
Under the current timetable, K sets now only operate peak hour services in the respective directions. However, with the upcoming April timetable changes, there will be few K set services left. In addition, these changes will also see the Mariyungs rolled out to the South Coast and the repainted orange OSCars performing suburban duties on the T9.
Spotting
Our first station we stopped at was Granville.
Prior to the first K of the evening arriving, we also spotted some B sets and a Tangara:

The K set arrived not too long after, and we hopped on it after grabbing some photos:

After boarding the train the arctic aircon was quite the relief, given the high humidity outside paired with warm temperatures.
Our next station was Yennora, where we planned to get some photos from the shared path/cycleway that parallels the rail corridor toward Fairfield.


The shared path is slightly elevated compared to the rail line, and the fence is low enough to stick a camera over, although a fully articulating screen is very much required.
Continuing our walk toward Fairfield, we waited at the level crossing to get some shots of a K set passing over, which can be seen as the feature image. Interestingly, this is the only level crossing left on the suburban network outside of the Richmond branch.
Also, we spotted a couple of other trains at the crossing before the K, including this 4-car Millenium set headed toward Leppington:

Just beyond the level crossing, further along the shared path, is a creek which the rail line crosses over with an arched brick bridge. The path isn't at the best angle to the bridge unfortunately, although it seems like a decent spot for a pan shot.

Also in the creek were about four shopping trolleys, which I am told are native to the area.
Lastly, as the sun dipped below the horizon we caught a train to Warwick Farm, which would be our last location on this trainspotting trip.

Due to the quickly fading light the conditions weren't optimal for photography, especially with a crop sensor which means the grain is a fair bit more visible in these shots.

Closing Thoughts
The K sets are definitely aging, and pending the introduction of OSCars to suburban service, it's difficult to justify their continued presence beyond a few peak hour runs. It would be wrong to say they are completely unfit for purpose, although they do lack modern accessibility and elements of their design are prone to abuse by buffer-riders. In fact, the problem has gotten severe enough for Transport to hire security on some services to sit in the unused² guard's cab in the rearmost carriage to dissuade cab break-ins and other unsavoury behaviour.
It's a bit of a shame that there are no plans for preservation, but then again THNSW is not infinitely resourceful. When they do eventually go, I'll miss their jolty starts, arctic AC, and distinctive brake smell pulling into stops.
Footnotes
¹: The C sets were another silver set, and had all retired by 2021, having been replaced by the Waratah Series 2 (B Set) trains.
²: On K sets, the guard is usually in the fifth or fourth carriage, in the middle of an eight car train, rather than the rearmost carriage.
