The GNR Howlden flat roof coach project

About 9 months ago I decided to start work on a rake of GNR coaches, mainly to run with the upcoming Rapido Stirling single. My Initial plan featured a pair of 4 wheel coaches and a rake of 5 6 wheel coaches. Since then I have done significantly more research and realized that just making a base rake of 6 6 wheelers would be best.

As of today I have gone through multiple drafts of the chassis and body design and I am at a point were I am happy with the overall design.
When it came time to design the chassis I split all the coaches into 3 different chassis types: A, B & C

Type A will not be used in this rake of 6 but I do plan to make a coach for it at a later date

So far I have managed to form a slightly dodgy list of 23 different diagrams and out of those I've settled on the following 6:

• Dia. 301 BPZ (full brake) -Type B chassis
  
• Dia. 34A BTZ (4 comp. brake 3rd) -Type C chassis
  
• Dia. 245 TZ (5 comp. 3rd) -Type B chassis
  
• Dia. 156 CZ (5 comp. composite 1st/3rd) -Type B chassis
  
• Dia.164C CLZ (4 comp lavatory composite (shared) 1st/3rd w/ luggage compartment) -Type C chassis
  
• Dia. ??? FLZ (4 comp. dual-lavatory 1st) -Type C chassis
  

So far I only have the CADs for the full brake and lav. comp., but they'll do (Note that I will add some more detail on the roof and that none of the wire parts have been modeled)
