Here's a short video shot yesterday evening at Bow Brickhill:
That's a very funky sound on 230004! Looks like they have good performance too, and I'm definitely feeling the need to travel on one ASAP!
Great video. Worth noting that they are nowhere near as noisy as the video implies - mobile phones tend to pick up background noise quite loud if there is no "foreground" noise to record. Note how noisy the 153 also seems.
Another vote of thanks to Bletchleyite for his thorough review.
This looks to be an excellent product from which many similar branch lines could benefit. (As well as those already mentioned I think Chiltern have missed a trick not snapping up a couple for the Aylesbury / Risborough branch).
Regarding the air cooling system, isn’t that what Chiltern’s 165s have? It works extremely well on those.
Is the failed engine concerning? I guess they must have been reliable enough during trials and it was just unlucky that one failed so soon into service.
Electric drive is far from a paragon of efficiency though (you'd have it in your car otherwise!). Bear in mind that DEMUs have become less common over the years. The fashionably more efficient alternative to a Voith hydrodynamic transmission is bus-type conventional automatic boxes as fitted to Class 195s. I'm told that while a Voith transmission is as you say stirring up and heating oil, this is mainly in first speed when the torque converter is in use and that in second and third speed efficiency is much better.Great performance even with one engine out. Fully functional they will no doubt match a 350 (up to a much lower top speed of course). Two engines out of four would be enough to match 153 performance, probably because unlike the Voith hydraulic transmission you don't turn a load of horses into heating oil up and making a racket, instead it is channelled more efficiently to the wheels by the electric transmission.

- I noticed more 'portly' and taller customers struggling with the airline seating which lacks room
In comparison to modern cars, a lot of Diesel trains can be quite noisy, which could be off-putting for people who have the choice between the two.
have you traveled in many 30 year old diesel cars or buses for comparison? They are a lot quieter than they were previously!
I'm planning a trip tomorrow to try out the new arrival but don't know which diagram it will be on. Would one of you kind people be able to advise? Thanks in advance.
Thank you very much for this - and also for your excellent write-up earlier in the thread.So far it's been on the Class 150 diagram, which is shown as 2 coaches in the PDF timetable on the LNR website.

All 3 units are already at Bletchley.Would there be a chance of the second unit arriving before the 15th of May?

Thanks, most appreciated! I'd best create a '2xx DMUs Needs' list today. I assume 230001 and 230002 are floating around somewhere and will, eventually, enter service somewhere?
Seems to sound identical to a D78 at speed.They aren't that noisy let Geoff Marshall show you round:
