Gradient and curve diagrams, Cudgewa post 1932 or 1950

 
  woodford Chief Commissioner

Anybody have the Gradient and curve diagrams of the Cudgewa line, either after 1932 when hume dam was first built or after 1950 when the level was raised. I have three copies all pre 1932.

A good portion of the line between mile posts 197 and 215 was shifted.

Hi Woodford. In the mid 1970s I purchased from the Association of Railway Enthusiasts a reproduction of the 1927 Victorian Railways Grades Book. I also purchased a supplementary grades book containing some updated diagrams and new lines such as the SG to Albury. I then proceeded to paste the newer new diagrams over pages in the  1927 grades book. I just went and found the book and the Cudgewa line is one of those with newer diagrams glued over the older diagrams. Using a magnifying glass I can see some bits with 1958 on them and words like "deviation 1958 + 91L" I presume that means that the deviation was added in 1958 and added 91 links to the distance. Is this what you are looking for?

Yes, the major deviation was completed in 1932 for the construction of the hume dam, then line was altered again in the late 1950's, when the lake was raised, this being completed in July 1958.

Can you do a high resolution scan of the pages concerned, I have done the entire 1926 grades book at 800 dpi(final image size 7000x3700), it would be nice this could be matched.

Most of the Cudgewa line is missing from this copy as the line was close by then.

Hi Woodford. Unfortunately, both my old flatbed scanner and a new 3 in 1 scanner printer don't go higher than 600 dpi. I'll send you a PM with some options. L1150:D

How many dpi's would depend on how good the diagrams are. I found the original curve and gradient books where done to a VERY high standard, with a high degree of accuracy.I found the distances where rarely more than 20 to 30 metres out, which is amazing on diagrams that are little more than 120 x 200mm. and each page covers 40 miles in 2 sections.

The 800dpi was for an original C&G book which are quite small, I lot of copies have been done to a larger size so just do the best one can, It WILL be GREATLY apreciated. PNG images would be prefered, if the scanning software can handle it. It would probably be worth while to get them up on the net somewhere as post around 1928 diagrams for the Cudgewa line do not exist.

The Book The Branch Line - Lloyd HOLMS has a copy on the back inside cover but Curves on half of it is hard to read.

However I have the document on the CD that I mentioned on your other post.

PM me and I'll organise to get it to you

Hi Woodford. After a bit of fiddling I managed to produce these. My scanner software didn't want to produce PNG's so I saved them in bitmap and used a freeware convertor. Perhaps not up to the standard of your other scans but fairly readable. One problem I had was that, probably due to the pasting of the new diags over the old ones, the pages are a bit buckled and scanners don't have any "depth of field" so some parts might be a little out of focus.
Anyway, have a look and see if they are any good to you.

They will do the job, it would be really excellent if the were sharper, a number of sugestions...

Try putting a fat heavy weight on the top of the page in the scanner to flatten the sheet I commonly use the 1926 Locomotive cyclopedia, its around 60mm thick and somewhat bigger than a page. By the look of the softening in the focus in the images, this should work.

If you have a decent camera (bigger than 10 megapixels) and a good lens you could try and photograph the pages. This is my prefered way of doing a book. Mind you I do have an excellent (read expensive) camera (a nikon D700).

Check to see of the scanner focus can be altered, this can be done in the Epson Photo 890, the focus can be changed to just above the glass.

PS: Otherwise they are quite excellent, exactly what I was looking for.

Managed to sharpen them up a bit using gimp so there quite good. An interesting point is is there not a real lot of help as all they show is where the line has deviated from the original allighnment. They do not show any of the new curves.

I have on all sections around Lake Hume, using Googlearth, measured both the chord and chord height of all curves. This was surprisingly accurate, calbration runs on known curves showed the raidius could be calculated to around 2% accuracy.

They would have been drawn much larger and then optically reduced for printing. You probably really want the survey plan and section drawings, these have more detail.

Yes, They would have been drawn initially probably at width of around 48 inchs, with 1 mile equals 2 inches. Drawn on what were known as "linens", The printing plates being done with a large process camera specficly designed to produce accurate printing plates.

Since then I believe most people have  not treated these drawings with anything like the respect there accuracy deserves.

I have the "plan" "property" and "section" drawings for the Beechworth to Yackandandah line, these three drawing sets have EVERY thing one wishes to model the line. It would be great if more of this historic drawings were around. How much survives I do not know, but  a greet deal of old railway information is inaccesable in "archival" storage in one of Victoria's major libraries.

The drawings for this line are particularly usefull as the old formation has been obliterated for a good deal of distance by road widening between th Beechworth Wodonga rd and Yackandah it self.

In November 1976 ARHS ran a mixed on the Cudgewa line with cars attached to the back of the regular goods. This involved using the down Spirit of Progress to Albury, a bus back to Wodonga with the mixed leaving after midnight, arriving in Cudgewa early next morning then, after re-marshaling, progressing back to Wodonga. The crew were quite laid back and allowed us to have some impromptu photo stops.  I was taking poor quality black and white pics in those days but thought some might be interested in a few of what I took. My memory is a bit vague so the locations may not be right.

Not sure where this one was.

I'm pretty sure that this is at the highest point on the line near Shelley
