This section was re-laid, along with almost all of the rest of the Noarlunga line - I remember seeing the construction crews at work here from the Anzac Hwy bridge. I agree, as with some other locations along the Seaford line, the ride quality is atrocious considering the track was rebuilt from foundation up.
Oh dear, that's rather uninspiring.
If/when the underpass access to the station gets completed, I'd be tempted to get off an inbound train and use an Anzac Highway bus route into the centre of the city. It would be a smoother ride and get me closer to my destination.
I tend to find the ride is worst at locations where trains get up to a reasonable speed. Admittedly there are not many of these, as most of the journey you will be either starting from a station stop, slowing for the next station or travelling at 25 m.p.h because there is a yellow signal. West Parklands and HC Beach/Lonsdale are where I find the ride worst - the particular motion can make me start to feel nauseous, and I never suffer from travel sickness normally. Plus I think it's worse in EMUs than DEMUs - presumably because the latter have more stabilising "ballast" slung beneath the frame.
I haven't yet ridden the parklands section on an EMU, but during the trips I have had on EMUs the motion seems to be mostly violent yawing from side to side, more similar to the nauseous rocking and rolling of the Flexity trams than the alarming pitching up and down I experienced on the DEMU going past the parklands. The yawing was violent enough to tip my bike over on one trip despite it being my wider flat-bar commuter bike and being parked upside down with the handlebars and seat forming a tripod - this was the first time I've ever had either of my bikes fall over on any AdMet train or even bus since I started putting it upside down in this way.
It seems to sum up my general impression of the EMUs quite well - that they are decent, but when combined with the brilliance of the DEMUs and the elimination of the faster services, we could well be in the world-leading position of being the first railway system ever where electrification was a downgrade. Everything about the interior feels cheap, as if the build quality reached a peak with the DEMUs and with the A-City it has now regressed almost down to the level of the Jumbos - but at least the A-City doesn't have the frame windup that the Jumbos shared with Australian cars of the era! The DEMUs all went many years before they needed even a cosmetic refurb, but I'd hate to see what the interiors of the A-City units look like in even five years.
The Bombardier Electrostar EMUs that I travelled on in Britain gave a similar impression - but then again Bombardier at Derby has been going through the motions like Dandenong for a few years. The Alstom Juniper sets were somewhere in the middle being almost as good as our DEMUs, while the Siemens Desiro units took it to a whole extra level beyond even our rock solid DEMUs.
A couple of times whilst travelling on EMUs I have heard a funny noise that sounds like a sping being dragged against something with a twanging sound at the end of it. Both times it seemed to eminate from above the roof of the leading car and not from the pantograph. Has anyone else heard this and does anyone know what it is?
Would be the air con I'd imagine but I don't know why it would make that kind of noise.
It could be the movement of the wires ahead of the pantograph making that sound - remember that the way they behave is dependent on numerous factors which change from day to day and across the course of every day with the weather.
The last time I used one, there was no chance of hearing any strange scraping noises as the A/C in the leading car was making a deafening roar.
