Gazelle 2-2-2 Drawings

[Ian AbbottParticipant @ianabbott31222]

So, I've uploaded the unfinished CAD general drawing of Gazelle, I'll update things as they happen, 'cos I'm not sure how long things will take.

This is a JPG, but I have DXF and PDF files as well.

Very nice work.

But, a question ->

You show the 'passenger' seating as running across the rear of the locomotive, but was it constructed like this?

I cannot find any pics of the very earliest 2-2-2T incarnation viewed from the rear, but I believed that there always was an entrance for passengers from the rear through a hinged door. A footstep was added slightly later – but maybe that was always there too, I'm unsure of my source on this point. Here is a 3/4 rear view of the locomotive showing the door, and a 'weather-shield' for passengers. The passengers were isolated from the footplate by a steel sheet running across the rear of the footplate area level with the back of the side-doorways – this is visible in many of the 'standard' 3/4 front views.

I dropped in and searched the Doman & Co. Ltd. archive, and on my searching could not find any remaining drawings pertinent to this locomotive. EXCEPT I did find one drawing, undated, untitled, no scale, which looks very much like the frames of 'Gazelle'. PM me for more info' if you wish.

You should note that the Doman archive has never been fully referenced and sorted since being saved from the closing works in 1975, so looking for information means sorting through the documents one by one. Much of the archive is in very poor condition with no conservation work having been carried out.

Regards,

Hi Phil,

Yes. I have the rear view with the door and canopy, but absolutely nothing from when she was new. I tried to imagine how she would have been used and thought that maybe passengers would have climbed on board from the platform. The entrance is back from the controls, so perhaps the crew wouldn't be in the way.

Either way, I still have to draw all the fittings and figure out the view from underneath. I'll put an alternative detail view of the rear, with the shelter and door, so we're covered whichever is correct. I also will add a detail for the 0-4-2 layout.

I have a few annoying little quirks from the DXF export, where radiuses on the chimney and dome have been given the segment lines, so ignore them. I'll figure it out in time.

Regards

Phil,

After looking at the rear quarter view, it seems quite likely that the rear door was there from the beginning. I doubt that it would have been added before the later modifications if it wasn't there from the start.

This view really shows how exposed the footplate was before the cab was fitted.

So here's the latest state of the general elevations. I still have backhead fittings and a few other items, and the motion, when I decide how that will go. The prototype motion might be a bit in the tiny side, but we'll see.

The Stephens drawing, is pixelated, so I've tried to guess what is actually there.

The DXF file has added some odd lines to a few radiuses, dunno' why.
