Hi all ,

Being a NSR devotee (both 1:1 & 2mm FS), I've attempted to use the magnificent product of Martins'  labours (</END_GROVEL>) to use to model Leek station. However, I very quickly came to realize that Martins' video (excellent tho' it is </END_FURTHER_GROVEL>) only really caters for the free-form school of layout design; My problem appeared to be far harder since I'm trying to construct a truly tandem turnout i.e. all turnout roads branch from on the same side of the main road, based on a scanned prototype track plan that has, in total, 7 roads branching from the main line via interlaced tandem turnouts.

After much cursing and a modicum of thought, I believe I have the best Fathers Day present - from myself :) - I came up with the following sequence to generate the overlayed turnouts (and hope it may be of interest/use to someone else in the same predicament) ...
  1. Generate a plain track control template following the principal route ('the spine of the branches') using transition curves et al
  2. Save it to background (recording the number)
  3. Copy it [the plain track template] to the control
  4. Insert a turnout into the plain track
  5. Adjust the position, handing, radius etc. to suit the overlayed scan
  6. Save & background the control
  7. Copy the newly created background template (number recorded previously) to the control
  8. Repeat steps 3 - 7 as required
  9. Delete a tandem constituent turnout to the control
  10. Make separate approach track
  11. Move it else where (to avoid picking up the wrong track later)
  12. Save & background
  13. Right click on it and delete
  14. Make separate exit track
  15. Move it else where (to avoid picking up the wrong track later)
  16. Save & background
  17. Right click on it and delete
  18. Repeat steps 7 - 15 until all branches have been created and all approach & exit roads deleted
After which you will, with a bit of luck and a following wind, have a set of tandem turnouts all following the same transition curve - all that remains is to sort out the connecting track (the recorded plain track template is still in the box), crossings and timbering as per Martins' video ... which I'm just about to start.

I'm convinced the above is extremely clunky and doesn't use the tool to its best advantage, but, so far, it's worked for me :D

Wish me luck.

Best rgds ,

Dave P

Hi Dave,

Happy Fathers Day. :)

A few points:

You don't necessarily need to move templates to avoid selecting the wrong one. If you hold down the SHIFT key, or put the CAPS LOCK on, the template name labels will highlight as you move over them and you can select the template you want by clicking on the label. This works even when several templates overlap, because Templot puts the name labels in random positions for this reason.

There is no need to keep copying stored background templates back to the control, if the transition alignment remains the same. After storing a copy of the control template, you simply adjust the existing control template to get the next turnout required (press the HOME key to see it again after storing it). Then store it and adjust it again, and so on. If the first templates get in the way, store them as unused (main > store as unused menu item) until you are ready to copy them all to the background (from the storage box).

Sorry, I didn't quite follow the bit about splitting and deleting approach and exit tracks. If the control template has some unwanted approach or exit track (after CTRL+F9 roaming, for example):

do > approach / plain track > crop all approach track menu item.

do > exit track > crop all exit track at joint menu item.

Then you can use CTRL+F6 to snake it along the transition without adding new approach or exit track.

regards,

Martin.

Dear Dave,
Sounds like a pretty amazing bit of prototype trackwork - any chance you could upload your scan, and/or .box file?  Can't imagine I'm the only one who would like to see this.
Regards,
Stuart

Hi Stuart ,

Methinx the scan is a far easier thing to understand, so I'll upload that first; A picture scan or two (will have to wait until such time as I am re-acquainted with my book collection) and the box file (such as it is - being a mess) to follow.

Note that the scan is a scan of a scan of a plan drawn prior to the up end being re-modelled (and IMO, made far less interesting) in 1914 - as you will doubtlessly infer from the filename.

The up end of the schema in this case is the left hand end - on the up side of which can be seen the interlaced tandem turnouts that have given me such trouble since I started (3 of the 4 attempts in 4 months have been abandoned whilst trying to properly represent this part of the layout).

I wouldn't mind, but the Knotty seemed to delight in their [interlaced &/or tandem turnouts] use all over the network - which altho' admirable in the distinctly urban setting for most of the network, is questionable is rural areas such as Leek.

Best rgds ,

Dave P

TFT Martin ,

You see, I rest my case :) It was, as I say, clunky and inefficient usage of a wonderful bit of kit but you obviously have the advantage of knowing it inside out, whereas I'm a mere beginner - I thank you for your enlightenment.

If and when I manage to conquer the reduction of all the sleepering and rails (to produce a workable representation), I then have to go on to address the additional problem at the up end of the station - a ladder crossover encompassing a single and a double slip all on a transition curve ... or just bastardize the scan and have the curve merely straighten out before the ladder is encountered.

I do believe that I'm beginning to enjoy the effort :D

Best rgds ,

Dave P

BTW, I'm sorry if I'm teaching my granny to suck eggs, but you could use something like subversion (SVN) or Git as version control tools to help you manage the plethora of previous built versions to which guess you referred to in an earlier mail. If you need/would like any further help/information on/with this, pls feel free to get in touch.
