Coradia and Adelante braking

[Philip]

Do any 175s or 180s still make use of the hydrodynamic brake fitted to these units when first built? I've not heard it used for years on the 175s though there's probably a few of these I've not been on for some time so was wondering if it is working on some of the units. Likewise when Northern were operating 180s I never heard it used, but do FGW/GC/Hull Trains use it?

Just seems a tad odd not to use it if it's fitted considering it reduces brake pad wear. The 185s also have the system fitted and it's used all the time on all of them.

I always assumed the brakes on a 180 were operated by jamming a crowbar against the wheels, judging by the sound effects!

The HD brake gave a lot of trouble in the early days of the 175 and 180 so it was decided to isolate it when the trains were still quite new. I think there was a trial on the 175s a couple of years ago to reinstate the HD brake but I'm not sure if they were reinstated fleetwide or if it was just a trial. I don't think it has ever been reinstated on a 180.

No, no, no, no!

They throw an anchor out the drivers window! Get it right .

Didn't they get through a set of brake pads every couple of weeks at Northern?

An Adelante is a Coradia.

Coradia was the generic model name by Alsthom (with the h at the time) for that tyoe of DMU - and EMU - as 458 460 and 334 are also Coradia models. (Juniper has yet a different meaning, also an Alsthom term.)

Adelante is a specific marketing name belonging applied by to the First Group applied to its Class 180s Coradias. Strictly, when a 180 os used by another operator outside of the First Group, the term Adelante should not be used.

I don't think it has ever been reinstated on a 180.

The HD brake itself was always a reliable bit of kit , the main problem was always the poor performance of the cooler group which struggled to cope with increase in coolant temperature caused by the rapid increase in transmission oil temperature when the HD brake was used . To help improve the general reliability of the 175 the last HD brake was isolated in 2010 and as far as I am aware there is no great rush to reinstate it even though the cooler group has been greatly improved .
I'm told by people who were around the 180 when the HD brake was working that it worked OK and didn't suffer overheating problems due to limited stop nature of the 180s work , the problem it did have was that was every so often the pipework between the transmission heat exchanger and transmission work burst and cause it to dump its oil and eventually it became so much of a problem that the HD brake was isolated . One car on a Hull 180 (110 I think) has a modified heat exchanger and improved transmission pipework fitted and has had the HD brake reinstated for quite a while as a trial which has been going very well and wouldn't be surprised if the HD brake is slowly reintroduced across the 180 fleet .

Post 2010, after the 175 HD brakes were isolated, ATW replaced the original brake disc design with a different, and in my eyes inferior, split brake disc. It's requires far more effort to stop the train than the original discs, which were phenomenal, and the latter versions caused quite a few brown trousers moments amongst the drivers who had been used to the impressive brake performance that the originals offered.

To be even more pedantic, it's Alstom

As he says though, it was called Alsthom with a 'h' in those days. It only changed to Alstom sometime in 1998.

Type was never spelt tyoe with an 'o' though.

Nope. See what I wrote.

Alsthom (with the h at the time)

Alsthom became Alstom in 1998.

458/460s etc were ordered in the same year but Coradia were an Alsthom concept rather before 1998 - the Coradia name existed at least in 1996 if not before.

Though even FGW no longer call them Adelantes; they're just "Class 180s" now. See for example the new "where to load your bike" poster which lists Turbos, HSTs and Class 180s.

3 or 4 years ago must be around the time I last heard it on 175s - think the last time I heard it used there were still units in FNW livery. Even when it was working it wasn't working on all of them and quite often only under one carriage if it was. Again, on 185s you can hear it in each carriage.

Does the noise from the HD brake on the 180 sound like the 175 HD brake?

Hull Trains still do
