    In engineering terms the two diesels were rather different beasts. The MAN diesel range used in the British hydraulics was essentially a basic engine design pushed to its limits to achieve an acceptable power to weight ratio - and it wasnt up to it, hence DBs rejection of it in their V200s. The Maybach engine range was much more developed in engineering terms with a tunnel crankshaft - massive roller bearings through which the crankshaft could be extracted from the one piece crankcase at one end - whereas the MAN had traditional bearings with shells in a split crankcase. The top end of the MAN engine just wasnt up to it either with no piston crowns cooling although Maybachs were also prone to exhaust valve burn out - D1010 was suffering from that when I had her on the "Western Requiem" tour in Feb 1977 but she still allegedly hit the 90 mark between Kemble and Swindon. Too dark for accurate timimg but she was always known as a good un. A significant effect on engine note will come from exhaust configuration due to resonant freqency and also from turbo noise - the lovely whistle on an MD655 over-run for instance. So will the D832 boys be mimicing the original exhaust layout - including moving the exhaust port from its central position on the roof to the correct offset position? Might have to issue drivers with respirators if they do as the 43s exhausts with this layout were always failing. Not aware 22s were similarly afflicted - but ought to give the most accurate sound reproduction! Kind regards Phil Edited to correct lack of piston cooling on MAN engines - Phil

    Hmm Have my cynical hat on here am afraid! Class 22 sounds on this sound mighty like an MD870 to me. Look at many of the steam clips on here - are the beats synchronised with the wheels? Not at all sure....if not then surely is dubbed sound? A lot of cine footage had dubbed sounds added subsequently - does anyone have the dvd, does the accompanying info make it explicit? That is not to denigrate the footage - it is superb - the sound is just a function of the technology in place when it was originally taken and we are damned lucky to have access to the video with or without original sounds. Cant wait to hear the MAN diesel when it gets put in to D832 - that will give us the answer I guess. However my missus says she doesnt know how I can get involved in these debates as I cant hear anything any way! Hee hee pass the herring aid - OK fish jokes has better be a seperate thread! Kind regards Phil

    Cheers - thought some more werent quite right! Not the first time have heard this - theres a DVD of diesels in Forest of Dean - cant remember which one but my good friend Mr Mabbutt has it - in which as suggested here a 22 has hymek sounds dubbed - and a 37 sounds suspiciously like it has been re-engined with a Sulzer 6LD! Kind regards Phil Bullock Edited to correct my appalling grammer. Worcester Royal Grammar School has a lot to answer for!

    As you say Nidge some cracking footage. But beware the sound track. That 08 2 mins in to the second clip sounds like a 14 to me! Notes are of Paxman rather than EE music I suspect.... Kind regards Phil
  5. Hang on - dont they all have Duff traction motors? :no:
  6. Thanks for pointing out the error in my suggestion chaps - sounds like that exercise may have been part of the Mirlees demise then? Hadnt sussed the larger grills as a Brush 2 variant either - cheers for pointing that out too! Phil

    That seems the most logical explanation! There is another picture of it bearing the sticker attending the Aschurch altercation which occured on 8th March 1969 in which D7038 was damaged - also D156 and D1754 involved. See http://www.railwaysa...hchurch1969.pdf - unfortunatelty two fatalities. That was the weekend Abbotswood Junction box closed as the Gloucester MAS scheme was extended northwards. Cheers Phil
  8. Evening folks Was about to make the same points as Titan re mechanically driven auxillaries but as already said no need to repeat. Pennine MC said "I recall reading that EE did actually offer to supply the last batches of 37s at 2000hp but BR declined, probably on the grounds of standardisation" - now if I remember correctly a re-engined Brush Type 2 - D5835 I think - was tested with an uprated engine at both 1600 and 2000 bhp. Not sure what electrical changes had to be made to handle that but presumably it was the test bed for this exercise? And was it therefore the only loco to operate as a Type 2, type 3 and type 4? Kind regards Phil Bullock

    Thanks folks - and I guess we should also not forget that the train classes were not a fixed item they did change around this time - and that something in the region of 25% of workings displayed the wrong code. Later pics of this loco operating in the Gloucester area all have her on class 8 workings. Cheers Phil

    Cheers Trevor Amazing what we can disprove even at this distance in time. Now we just need to wait for D6320 too ... The Dec 68 sighting is the earliest one yet at 85B - transfer to 82A is listed for 9 week period ending Jan 69 so that fits nicely - would be nice to know when she last worked in the area too. Kind regards Phil

    Thanks Geoff that confirms my thoughts - was hoping we might unearth some more specific sightings too! Kind regards Phil Bullock

    Hi all Have been having a conversation with Ben Jones of Model Rail re their review of the super model of D6331. That states that the loco was stored at OOC from 1969 and then towed to LA for spares recovery - catching fire en route! From evidence D6331 was most definitely not stored after finishing at Newton Abbot in 1968 - she was working off Gloucester after this as allocated to 82A BTM from Jan 69 and got as far north as Worcester and Bromsgrove in this period. If you do a search for D6331 on flikr you'll find a couple of images and the class 22 page on the miac website also has some gen. I saw her working at Abbotswood on 20.6.70 and she was stored at SPM by July 71 following withdrawal in March 71. Does anyone have any other gen on her movements or workings between these dates please. 1971 was class 22 last knockings - was she actually working for the first 3 months of that year? Heres hoping! Cheers Phil
  13. Thats interesting gen. Assume they found some other footage that was a little 'otter then? Coat on and leaving..... Phil

    Hi there For headcodes take a look at http://en.wikipedia.org/wiki/Train_reporting_number. However the last two digits are route specific identifying trains on a given route. Studying photos 8.50 and 8.51 look pukka for D6331 and D6320 when they operated in the Gloucester area in the late 60's - early 70s which leads me to believe that these were the codes for the local Gloucester trip workings. For other areas suggest you study photos or better still get hold of a working time table for your area - they are a mine of info! Kind regards Phil Bullock

    RM web special? Count me in! What would be required? A pre paid order? Credit card at the ready...... Phil
  16. Hi all Hopefully wont be too long - see Just wish we had the same for the class 22! Phil

    Hi Nidge afraid not! Must have gone in to the ether will email you to establish link Cheers Phil

    Ye ha! So thats D6320 and D6331 for Abbotswood then - the Gloucester twins of the late 60's early 70s. What price Lister name plates for D6320? Has anyone got a picture of that unofficial name please? Phil

    And heres D6324 clearly in green http://www.flickr.com/photos/geoffsimages/6205364198/ and on the same day but from the opposite angle http://www.miac.org.uk/stored85a.htm - so thats no blue and no full yellow then! Phil

    Cheers Dave Is there now clarity about which locos are coming out in which livery? Many thanks Phil
  21. Hi Andi Love that curved diamond. Is it scratch built? Should have done that on Abbotswood , would have maintained a smooth transition for all those long 1Co-Co1 bogies! Phil
  22. Dave that is a super photo! Many thanks for publishing Cheers Phil
  23. Thanks Mark that is very useful gen 6V06 is news to me though - thats the trouble with losing the headcodes off locos! Cheers Phil
  24. Hi folks Why Abbotswood? Heres why.... Favourite photo of all time... 8.12.76 1048, 20228/119. Many thanks to Mike King for copying this superb photo for my use. Was this the last time a Whizzo worked the clay? 1048 Western Lady Abbotswood.zip Phil
  25. I know ... lets have a pilot scheme - hey we could call these the pilot scheme locos ... thats bound to work isnt it? :rolleyes: And surely no-one would go in to production until the original ones were thoroughly proven in service??? Hee hee - just adds to the reality!!! Kind regards Phil Bullock
