Well NIR fleet came up trumps and laid open the whole thing ! The generator packs were changed and after sometime in 1991 the detriot V8/ markon pack changed for a Cummings/Dale pack.  I was kindly sent a CAD of these changes - not fully detailed but a good use.

The single sliencer still offset to fit loading gauge  The dale gen pack 3185mm long so roof hole that size plus a small bit. I had wondered why the depressed section was called a bath - it does not have vertical sides. The bottom  of the  "bath" is 950mm The top is 1100. The Dale/ Cummings silencer  scales at 500 dia and is about 200mm above roof line. 1900mm long - just over 6foot long and 20 " in dia.   

Pictures in the Irish Rambler book and on Flikr show the first brakes had the Dale sets 1992-4 period but as late as 1998 possibly 915 had two still.  Over to you gents if you can look in pics and see if dates can be confirmed.

Regards and thanks to Ddu Varren for helping in spotting variations and dates

Hi 

The rolling advance programme with updates works well - it did for Stalin?!  Yes - agree the big Island is very fickle and very changeable with  posturing and the like. However as MM has found out the Chinese factory act is a strange one  on an entirely different level.  Dapol have now introduced albeit in O gauge wagons using new British created tooling. I guess getting tooling out in good order from china will be very expensive if the stories of sitcky hands is true!  Dapol might have capacity and a product awareness worth investigating ? - just a thought.

Thanks for asking the customer base and as noted better than the perceived big   players - you would be surprised at the low headcounts at the other big name players!  But good for  you.

I will as anside buy some of the 3D 42foot flats and soon be getting a second A class just to ensure you do produce then RTR as I am almost finishing my efforts

Hi Broithe,  

Yes a possible reflection , I noted in my agreement to NIR to the instruction it was a shame as vehicles long gone but I guess its policy. Certainly Bombardier see vehicle drawings as commerical items and do not share other than some GAs - which is all I got from NIR but it certainly helps.

Robert  

Hi Well after a quick email exchange  with NIR fleet engineers I now have a GA similar to 9811 but for 91x vehicles - It has the roof detail for the access panel and a side shot so now I can start , however I was refused permission to upload to any forum site . If you want a copy PM me.  

FWIW the cut out is 2700mm x 1000m and for 8911 the silencer is 1800 long, 920wide and 370mm deep. Still not got the dia of the silencer on the 91x vehicles but I can now cross reference to details I have for several similar BR/ royal gen cars.

I have still left a request with NIR for any detail drawings fleet may have  so hopefully more in a while.  A big thanks to all who have responded so far!

Robert,

No need to struggle for drawings, already in circulation!

Great drawing thanks, but drawback nothing on roof mod, such is life ...

Robert     

Hi Thanks for pic.  Helps a lot. What chance you or anybody can lay hands on a side on shot. In the books I have and on the web we have all taken oblique shots !!  I have some almost head  on shots from the roof so a downwards one would be good as well.  

The penny dropped a bit of course and I will contact NIR and the good lads at Whitehead to see if any drawings to hand. 

Would anybody be interested in a  3D print version?

Robert   

Hi Thanks, looks like the MIR etched sides - I have a very filled airfix part done and this helps alot .

I have found an old Railway modeller issue with the HST gen brake that does  look very similar as a starting point. 

Robert 

Hi Just a quick one anybody got details of the NIR gen brakes - I am after the elusive roof details for the silencers and hole cut into roof.  If you have any contact details for who might have a drawing or could post on here it would be really great !

Thanks

Robert - currently gluing brake gear on bogie tankers, but staring at a pile of part built/altered NIR Mk2s. 

Hi Very good models and crying for a bit of weathering, Just to say was the A class ref a spoiler ? Just about to finish one so expecting the worst or is it the best from the boys!

Hi 

The Bill Beford jig is very good I tape off both sides of the one I want and use  a pair of square jawed pliers to make first bend - this into the hole and then pull on wire as I bend on the outer notch some times a twist with pliers to get both legs in the same plane helps - as does making several more than needed to allow selection of the best.  

If making several differing lengths I start with the longest and if I mess up I can cut off excess and use on a shorter one, just saves on wire!

I was taught many years ago if making more than one thing a jig will help reproduction - and this jig has given years on service and has been borrowed by friends. Whilst reasonably priced makes a good club investment as on your own it might not get that much use.    

Robert  

Hi have to say while new to me looking inside the cover looks like I am two years behind - which is about right for me , first published 2015. 

Still a great read 

Robert 

Gents,

Please can you point me in the direction of any diemensions for the silencers and roof mods or even a source of a drawing.  Looking to cut into a lima roof panel and was hoping to do better than best guess.

regards

Hi ,

Well Santa was kind with a new book, Irish Railway Rambler by Micheal McMahon from Colourpoint`s fine stable! ISBN 978-1-78073-075-2.

A great set of pics and extended captions  with good pics to help modellers. I have now  read it fairly well twice and to my untrained view a good read and worth my 16 earth pounds - other currencies available !

Robert
