Final one for a while.


The D1:



The D2:



The D3:



The D4:




Next might be side-on shots of VR wagons, but not for a while - will they help? If so, I will scan some.

Sorry to drag an old one up...

I have been doing a little research in regards to the early history of these locomotives and was after some more information. Considering these engines have been created in MSTS I thought someone may be able to help me with these enquiries.

The DDe tank engines (later D4) were constructed so that if they were made redundant after electrification of the suburban system, they could be easily converted to the DD tender engine. The DD tender engines later became the D1 class with saturated boilers, then D2's with superheaters added to the old boilers, then D3's when they were fitted with a new superheated boiler, based on the K class design.

The new boilers based on the K class ones were bigger then the old ones of the D1 & D2 flavor. My question is, how much so? Can anyone provide me with details in regards to the difference between the size of the D1 - D2 boilers compared to the D3?

Thanks in advance,
Rodney

I don't have any actual plans for the Dd or D3 boilers, but I do know that the cab had to be raised by about six inches to accomodate the larger firebox dimensions.

The only thing I could suggest without proper plans or blueprints is to head to the ARHS museum with a tape measure and measure the boiler height and diametre on the D2 and D3.

It'll be a while till I can get down that way again to do that sort of thing, so that is about all I can suggest. You could contact the ARHS Archives, and see if they might be able to help too.

I have the VR Boiler Data from Newport

The Boilers Shown are:

D1 Copper Firebox
D2 Copper Firebox
D3 Copper Firebox
D3 Steel Firebox

Send me A quick PM with a valid e-mail address and I will see what I can do

It will need to be quick as I am leaving on a very slow 75 day cruise to Dampier and expect to be out of internet communication after December 18th.
