Never mind the quality, they're priceless Phil!
There’s some interesting stuff on there.
I guess like all these things the Paxman engines had their own sound. The HST had it when on low revs perhaps?
I was chatting to nice chap recently that remembers seeing a class 22 at Newquay when he was a kid...
Who might that have been then? .....I've been and still trying to get to the Facebook page but sadly to no avail, excellent thread is this btw.
I've been digging in my slide collection again, I think this might be an appropriate time to post this....
Most interesting thread. I've learned a bit about the different classes of diesel hydraulic locos. I do agree on a new build 41 being more interesting than a 43.
How much of a difference is there really between the UK loading gauge and the V200? Since I was thinking of the possibility of using the V22 and having a heavy strip down and re-fab into a warship class locomotive could most of the gauging issues be corrected for during this process? Or would the frame still be too wide?

Ok a little about the MAN this PU was a prototype in 1938 someone very kindly locked it away from the Nazis until after the war. Engine makers made PUs to DB spec hence several similar V12s
NBL design the big D600s themslves, based on 10000 drawings for the bogies and frame/body. They are oft referred to as CLass 41s, but didnt make it long enough. They are A1A-A1A
They built an electrical Type 2 Class 21, and later Class 29 the 'Sad=Eyes.'These had the ubiquitious Commonwealth bogie
And comparative the Class 22 shorter and with an NBL built up bogie
The V200 were the first monocoque locos in the world, with their baby V80s.
The 42/43s were based on this design, as 'quarts in pint pots.' Originally the 43s were going to be numbered D605-638, but were later the D833s/Class 43 these are B-Bs Swindon rejected the pilot D600s as too heavy, basically.
And the Blue Pullmans also had the same NBL/MAN engine, I think mine was originally retained as spares for these as the cooler group fan may be out of one!
They managed about 50million miles, so despite a number of issues, they certainly ran a lot!
Didn't the 41s go to Landore for a period at the end of their careers? Presumably to move unfitted coal wagons up and down valleys! Don't think it lasted long and given the need to train drivers and fitters for just five locos seems an odd move.
I visited Swindon Works on a school railway society trip (every school should have one ) around 1970/72 and there were rows of 22s and 42/43s waiting to be broken up.
Plenty of interest in all things hydraulic here though.Never ceases to amaze me how little interest there is in D6332s engine. Didnt realise how tribal diesel emthusiasts are. Often down to the exact livery or number.
I’m holding out for a Maybach due to the Mercedes connection.And knowing Mr Cowley rather well now, I'm fully expecting questions 4 & 5 to be along the lines of.....Will it fit in the back of my Mercedes van, then......How much are you asking for it?

My friend Paul is interested in the MAN engine for his Fiesta though .
Probably easier to fit the Fiesta in the MAN!
Chaps, it's all a bit hypothetical without a fair few million to back up a newbuild locomotive.
Business Case means people prepared to donate to a project, and there is not the funds. Most new build steam save a few with big money backers grind to a halt on the crank axle.
Lets be frank, of the 12 surviving hydraulic mainline locos about 5 and a half work, they are beautiful, difficult to maintain, with few spares, the guys on them do a sterling job and would hate all that expertise to flee to a newbuild 41 at the expense of others.
The 41 is an engineering nightmare, unless you made an electrical lookalike.
The transmission poked through the centre pivot and lay close to the centre axle.
The 2 spare 42/43 bogies are retained by their owners for rare spare parts.
If ONSLAUGHT ever comes up for sale is the only realistic way!
A proper new build NBL seems beyond us.
The Baby Deltic shows us the way.
They actually worked well for the vast majority of the time. The key issue for all hydraulics was the decision to give up steam heating, and do instead ETH tapped from the generator - which in their case, they had not got ...I get very confused by these funny western things which all seem the same but all seem to be different. How come so few made it into preservation?
