Hi everybody
Its about 4 or 5years since i've used templet and quite a lot has changed! When I last used it, I managed to create a complete plan of Dowlais Caeharris, however when I look at now i've realised that i didn't really know what i was doing. So I'm thinking of starting again and was wondering if somebody could help me load up and scale to the correct size, a scan of a 1932 plan of Caeharris. All i've got to go on is that the map was drawn at a scale of 33ft to 1inch.

The last time I used it I just tried to enlarge it to fit the templates, but i don't think i was very accurate, so any help would be much appreciated.

Hi Ian,

I'm not sure what you are asking for in the way of help.
The scale ratio is 1:396 for the drawing, (being 1" to represent 396").
If your scan was done at 100% then the input method should give you
an accurate size for your chosen modelling scale.

It has been a while since I did this myself but it is happening again
in the coming two weeks. Until then I'm not up-to-date with the
current input menu if it has changed.

Regards, Matt M.

Hello,
         I think this tutorial is what you may need.

2110_200947_070000000.png2110_200947_070000000.png

You will find it in the videos and tutorials at the right in the Templot Companion box.A lot of the tutorials refer to older versions of Templot but much of the content is still applicable.

Regards.

Hi Trevor, Ian,

Sorry, that video is somewhat out-of-date -- I have been intending to remove it.

It is no longer necessary to save the image in BMP format in the same folder as the BGS file.

A PNG image is now recommended, and it can be anywhere on your computer.

Here is a more up-to-date bit of tutorial:

(In the next program update it will be possible to paste an image directly from an image editor program into a picture shape.)

regards,

Martin.

Its not as easy as you think!

By pure coincidence after a 25 year break I started raking through cupboards at the weekend and decided I might model Cae Harris in P4: whether I can model the track is an open question. Dived into Templot for the first time and successfully imported a scanned image. I have three maps of Cae Harris:
- A line drawing from GWR engine sheds, dated 1897 and with a scale. The text states the engine shed is 120ft x 50ft.
- An OS extract from 'Cardiff to Dowlais', nominally 25" / 1 mile. The engine shed is a different shape.
- A plan I bought from an archive about 25 years ago, dated 1910 and nominally 2 chains to an inch.

If I believe the plan (remember the scale on the drawing may not be the scale of the reproduction) the shed is 260' x 109'.

If I believe the OS it is 200' x 46'.

If I believe the sketch it is 112' x 49'

So I am struggling. What I need is a fixed dimension I believe to calibrate the scales on the drawing.....

The width can be estimated by the number of tracks going into it, and making any required, inspired guesses based on photos you hold. Ditto length from comparison with known loco/wagon in front.

http://www.alangeorge.co.uk/dowlais_caeharrisstation.htm  has photos of the shed to enable you to do this, - seem to be 3 roads at say 12' spacing plus end errors would be nearer 46' than 109'
I don't know the length of the loco in front of the shed, that's your pigeon & puzzle.
Seems as if OS is better than the plan, by all accounts, just by looking at the photos, and noting the ratio of the sides/ends.

I've just followed Martin's advice….Thank you…. and its worked perfectly, i'm up and running!
Martin, I'd forgotten how totally addictive templot is, you've created a wonderful piece of software.

CPM, i'm working off a 1930s GWR plan drawn for the installation of the water tank, so i'll try and work out the dimensions of the shed tomorrow evening.

Another way to get a precise dimension is to use the old-maps.co.uk website. Once you have zeroed in on your chosen location, click your mouse on a readily identifiable reference point, note the coordinates, and then do the same at another point a reasonable distance away (to reduce errors). You can then use subtraction between the two X and the two Y coordinates to get a right-angled triangle, and finish off with Pythagoras' theory to get the distance from the hypotenuse.

Hi CPM

I've had a look at my 1930's plan and rekon the shed is about 118' by 50', which is the same as one of your plans. Some of the plans by give a wider width because of the sand bunker attached to the east side. Hope this helps

Hi everybody
Its now been two years since i was last using Templot (i need to retire) but with some spare time over the holidays i thought i've a go.
Anyway even with my lack of railway knowledge i soon got back into it. 

However, i'm beginning to think that i'm misreading the 1930s plan that i'm trying to follow. I've always thought that the lines on the map represented the rails, but things are getting so congested that I'm beginning to think that they could represent the the sleeper width. What do you think, do I need to enlarge the map? I've attached the map so any help would be gratefully received.
