The GNR Howlden flat roof coach project

Donald9Douglas10Oliver11mp · 2024-09-05T03:40:41+00:00

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...

It very much is! More specifically the train shed that is now platform 4!

I really liked how the image showcased a lot of the early GNR vehicles.

I’ve managed to Identify that the second line from the right has a rake made up of a: Dia. 303 Full brake, Dia. 281 Brake third with revised duckets, Dia. 245 third, potentially a Dia. 142 luggage composite, another Dia. 245, a Dia. 128??? lavatory luggage composite and a pair of some kind of 6 wheel full brakes
As for the line third from the right, my guess would be a Dia. 245, The soul built Dia. 149 luggage mono-lavatory composite w/ third class coupé (no 277) (Just a day before I thought I would never find a photo of it and even though it’s no ideal it’s still so incredible, considering that there was only one ever built… and at least out of the 6 wheel coaches it’s my favorite diagram), a Dia. 156 composite and a Dia. 281, then followed by a log rake of 8 & 12 Howlden clerestory corridor stock.
The rest of the coaches are some Howlden flat roof 8 wheelers, a Gresley 8 wheel coach on the right most line and a lot of the 8 & 12 clerestories.

8 wheel bogie chassis half baked prototype.

My initial design for this type of chassis made use of clips, however after printing I unfortunately realized they were to brittle so I changed the design to use separate pegs (which you can spot in the foreground of the first photo). As for the bogies I realized that not only did some of the detail require a complex support structure that proved impossible to remove, but that it didn’t allow for the pegs to be fitted, so I’ll have to change that to be a separate part. The bogies aren’t actually fixed in these photos due to afore mentioned issues, but the main thing I was concerned about was whether or not the chassis would be able to negotiate 2nd radius curves and thankfully it can and with ease.

I’m currently running low on wheels, but I have enough to make at least 3 more coaches. The first one will obviously have to be another brake, as to not make the rake illegal, and as I have recently really been after more full brakes, perishables vehicles, PMVs, GUVs, CCT, etc I feel it’s only right to make the Dia. 301

Donald9Douglas10Oliver11mp ,Because it’s my favorite of the 6 wheel coaches I was also thinking about going for the Dia. 149 Donald9Douglas10Oliver11mp & I definitely want to make some kind of 8 wheel vehicle, potentially a Dia. 190 Brake composite, which looks something like this:

LOL…excuse my laugh but the last picture above of the water closet reminded me of my trip to Switzerland 35 years ago. Needless to say the major mode of transportation, at the time, was the electric train. Up until then I had not rode in a real train (excluding park trains Disney, Busch Gardens, Greenfield Village) and to my surprise when riding a train from Zurich to Montreux, I had to use the on board Loo and to my surprise…when I opened the lid, it was just an open straight pipe to the sleepers rushing by below. I had always thought that the discoloration seen between rails were billions of oil and grease drips from the tens of thousands of trains passing through over the decades………..now I know what it really was….😱😌

Donald9Douglas10Oliver11mp

Super well one thing is for sure… There was no unpleasant smell left behind, so I guess in that sense it was quite a smart design!

Super

Donald9Douglas10Oliver11mp

So I just realized that there was 1 more Diagram I could have made w/ the current chassis and I’m glad it’s a composite and an actually decent one at that as all but one of the current composites are pretty useless…
So here it is:

P.S. I will probably add at least the 2nd alt. length soon and also I’ll update the images of the Dia. 164C as the orientation was incorrect

So… The roof wasn’t sitting properly, but I think I’ve come up with a solution!

Donald9Douglas10Oliver11mp

To aid in searching for certain diagrams over the last year or so I’ve developed a notation to display the internal layout of virtually any coach in the smallest amount of space and with the least amount of specialized characters while squeezing in the highest quantity of information.
To start, however, I’m going to start by explaining the basic principles behind the LNER and later BR coach coding system which gave each vehicle in a train a telegraphic code composed of either a series of letters with individual meanings ( BCK - Brake Composite Corridor) or an acronym CTO (Open Carriage Truck) here are the basics:

B - Brake OR Buffett
G - Gangway (Corridor connector)
NG - Non-gangway
P - Pigeon (LNER vans for luggage, mail & parcels)
L - Lavatory (only mentioned in the case of non-corridor stock & multiple units(EMUS & DMUS))
SL - Sleeper
K - Kitchen OR Corridor (corridor joining all compartments)
k - Semi-corridor
P - Pantry OR Pullman
O - Open (no partitions between seats)
o - Semi-open (a combination between an open section and either a corridor or compartment section)
F - First class
S - Second OR Standard class
T - Third class
U - Unclassed
C - Composite (More than one class of accommodation)
Y - 4 wheel vehicle
Z - 6 wheel coaches

Though these codes allow for a pretty good description of modern stock, for rolling stock dating back to eras 3 and especially 2, they don’t quite make the cut as, for example, the 3 classes of accommodation system creates 3 different types of composites:

1st/2nd
1st/3rd
2nd/3rd
1st/2nd/3rd

All denoted by the letter C, and though this was the way it was done in practice it isn’t really what I’m looking for, and so here are the basic principles for my system(I have also added some examples to aid in understanding the notations):

I.Partitions All vehicles have some kind of partitions like end walls or in this case they can also act a a separator between the individual blocks of he system:

| -Solid wall (no access between the individual blocks)
EX: L&YR Dia. 8: | 3rd | 1st | 2nd | 1st | 3rd |
=| & |= -Corridor connector
⁞ -Open section (Blocks found in the same section of the vehicle)
EX: GNR Dia. 277: | B ⁞ Mail & lgg | 3rd ⁞ 3rd ⁞ 3rd ⁞⁞ Lav |
⁞| -Partition in open section (Found between smoking and non-smoking open sections)
⁞⁞ -Door
⁞ ⁞ -Optional Door (as the blocks are listed linearly this allows for corridors to clearly join the compartments individually)
/ -Parallel blocks
EX: GNR Dia. 253: =| V ⁞ ⁞ Lav ⁞⁞ 3rd ⁞ 3rd ⁞| 3rd ⁞ 3rd ⁞| 3rd *⁞ 3rd *⁞ 3rd *⁞⁞ B ⁞ Mail & lgg |=

II.Classes:

1st OR F - First class
2nd OR S - Second class
3rd OR T - Third class
0 OR U -Unclassed

Notes:
1. If underlined the compartments can be accessed directly from outside (Unfortunately this is currently not supported by the forum, at least to my knowledge, however it’s not entirely necessary)
2. If crossed out the compartment is a coupé(half compartment)
EX: GWR Dia. E45 & F8(Slip): | B ⁞ Mail & lgg | Lav ⁞⁞ ⁞ ⁞ 3rd ⁞ ⁞ 3rd ⁞ ⁞ 3rd | 2nd ⁞ ⁞ Lav / Lav ⁞⁞ 2nd | 1st ⁞⁞ Lav / Lav ⁞⁞ ~~1st~~ |

III.Special variants of compartments To denote things like Saloons, I’ve come up with a special notation as to avoid spelling out the word SALOON every time it occurs as such here it is:

<letter code><No. of seats>(<class of accommodation>)

If it seams complex, don’t worry the only thing you really have to remember is the codes for each type of special accommodation:

S - Saloon
EX: SE&CR Dia. 314: | 2nd *| 2nd *| 2nd | 1st | S9(1st) ⁞⁞ Lav / Lav ⁞⁞ 1st | 1st |
L - Lounge
EX: GWR Dia E39, F6(slip) & F22(slip): | B ⁞ Mail & lgg | 3rd ⁞ ⁞ 3rd ⁞ ⁞ 3rd ⁞ ⁞ Lav / Lav ⁞⁞ 2nd | 1st ⁞⁞ Lav / Lav ⁞⁞ L4(1st) |
R - Restaurant OR DS - Dining Saloon
EX: GNR Dia. 64: =| V ⁞⁞ R8(3rd) ⁞| R12(3rd) *⁞ ⁞ Lav ⁞ ⁞ K ⁞ ⁞ P ⁞⁞ R4(1st) ⁞| R4(1st) *⁞⁞ V ⁞ ⁞ Lav / Lav |=
SL - Sleeping accommodation
EX: LNER Dia. 157: =| V ⁞ ⁞ Lav ⁞ ⁞ SL1(1st)x10 ⁞ ⁞ SHOWER ⁞ ⁞ ATTENDENT COMPT. ⁞ V |=
OBS - Observation Saloon
EX LNER Coronation observation coach:=| V ⁞ ⁞ STORAGE ⁞⁞ L5(3rd) ⁞ OBS12(3rd) |

IV.Other compartments:

B - Brake
Lav - Lavatory
lgg -luggage
K - Kitchen
P -Pantry
V -Vestibule
Mail
STORAGE
BULLION - Referring to vehicles that were used to carry gold and money (EX:LSWR Dia.2111)
SHELVES

V. Other notations:

1.* -smoking compartment (**, ***, ****, etc for alt. configurations)
2.# -Ladies only compartment (##, ###, ###, etc for alt. configurations)

Now you may be wondering why I am putting this here, well as the first “Batch” of 6 wheel designs are done I’ve taken the time to write down the diagram list for them using this format and I will be posting it very soon and am planning to link each diagram that I’ve made to the post about them; This would act as a simple place to find all the posts among all the progress updates, drafts, comments and anything else…
In a way It probably would make sense if it were the first post on this thread, but as I do want to keep the original as is I would need help moving it there. In the future The Diagram list would be expanded with the other types of coaches and I have even written out the Diagram list for another companies 6 wheel coaches, however those will get a thread of their own!
