If they are wedded to cheap CAF units despite their serious design flaws, they should make a more serious purchase of DEMUs with a convert to EMU option or even get CAF to quote for a genuine hybrid BEMU.
Hyperbole aside, would you care to list any of these serious design flaws?
Miles off the mark, I'd say. Some niggles and annoyances, but hardly anything serious or flawed - just as you could say for literally any other unit.
That's probably the point though. They are a 2020s product which is better than 1980/90s products but inferior to a decent turn of the century product (so a probably 25 year old design). Hardly great.
Except you're viewing this from an extremely one dimensional point of view. Yes, a 170 rides better and has a comfier seat, but otherwise, they're lacking. They weigh 15 tons more than the 3 car 158 equivalent and so struggle massively for power (and to keep time). The air con isn't super reliable and the units really struggle for cooling in the summer. They don't drive particularly well and certainly aren't a forgiving unit during anything other than ideal rail head conditions. The cab is small and the desk not all that well designed. The PIS on a 170 doesn't have an inch on the functionality of that on a 195.
From a performance, operational and customer service point of view, the 195 is superior by a long mark. We are quite literally disregarding all of these excellent features of the newer unit because some people dislike a knocking bogie and a slightly firmer seat.
It’s not an agenda, I just genuinely don’t think they’re very good trains. I wouldn’t take them over any of the aforementioned stock, mainly because I don’t think they particularly ride better than any of them.
Oh come on, if you can disregard all the short comings of a 150 just for the sake of a firm ride in the 195s, I'd call that an agenda. I won't list the shortcomings of a 150 because it's been done to death - if you can't objectively see how the 195s are leagues above them, then you're not taking a balanced view here.
I’ve excluded the 331s from this criticism, despite them being just as bad, they’re extremely quick off the mark
And for a DMU, as is a 195.
I’ve tried them on several different occasions, on different types of routes, and the incessant *CLONK* sound when going over bits of track irks me to my very core. I’m not someone to usually notice bad ride quality, but it can’t be ignored. The build quality is extremely disappointing for a modern day train, it feels like they were rushed out as quickly as possible, with corners cut to save money, and marketed as “better than a pacer”, which, yeah, sure, they are, but this isn’t exactly a groundbreaking revelation
Care to list the build quality issues, ride aside?
I think you've got to look at the ride quality issues from the perspective of what was attempting to be achieved; weight reduction for reduced track wear. To say what the units have managed to pack in, in terms of facilities etc for a given mass - I'd say they've done a pretty good job. If a firm ride is the only compromise for that, it's a compromise I can certainly live with.
