Hallo!

I am working on a turnout from the Railroads on Bornholm (De Bornholmske Jernbaner, DBJ). It is a 1:9 turnout, Radius 130 m, timber is 185 mm width and 1800 mm length, adding 100 mm in length to the timber, sleeper is 1800 mm length and 185 mm width.

I have attached three pictures, one with the complete turnout overview and one detail of the switch part. The third is my model of the turnout in Templot:

3585_241550_030000000.png3585_241550_030000000.png

I have tried to model it in both a curved and semi-curved version, mainly because I really could not figure out what it was precisely. The version you see above here is the curved version. I think it fairly good.

I have attaced the .box file as well, and this turnout is placed in x: 193 and y: 729.

As you see on the picture, the timbering is wrong, and I simply am not able to find out what I have done wrong. Furthermore, I am not sure if I got the all the switch data correct either. My input is here:

Dimensions  for  1_9-R130_Curved_timbered  Switch :
--------------------------------
 
Dimensions are in FULL-SIZE prototype MM, with model conversions at 3,5 mm/ft.
 
This switch is a CURVED pattern switch:
 
lead length to heel (incl. planing) = 6502,4  ( 74,74 model mm )
offset at the heel (heel spread) = 238,2  ( 2,74 model mm )
 
switch radius = 129997,2  ( 1494,22 model mm )
 
length of switch-front (stock-rail joint to toe) = 1498,6  ( 17,23 model mm )
length of switch-rail (blade) = 0  ( 0 model mm )
length of stock-rail from joint = 0  ( 0 model mm )
 
deflection angle at blade tip = 1 in 86,30 RAM  ( 1 in 86,30 CLM )
planing length (along stock-rail) = 3014,16  ( 34,65 model mm )
heel angle = 1 in 16,20 RAM  ( 1 in 16,22 CLM )
 
FB switch-rail foot-width at blade tip (from stock-rail gauge-face) = 0  ( 0 model mm )
 
sideways depth of joggle = 9,53  ( 0,11 model mm )
joggle-length in front of blade tips = 152,4  ( 1,75 model mm )
-------------------
Timber spacings (to timber centres) :
 
switch-front is sleepered:
spacing back from toe (blade tips) to first front sleeper (J1) = 629,92  ( 7,24 model mm )
spacing back to next front sleeper (J2) = 454,66  ( 5,23 model mm )
spacing back to next front sleeper (J3) = 749,3  ( 8,61 model mm )
spacing back to next front sleeper (J4) = 0  ( 0 model mm )
spacing back to next front sleeper (J5) = 0  ( 0 model mm )
 
spacing forward from toe (blade tips) to first timber (S1) = 50,8  ( 0,58 model mm )
 
spacing forward to next timber (S2) = 499,87  ( 5,75 model mm )
spacing forward to next timber (S3) = 519,94  ( 5,98 model mm )
spacing forward to next timber (S4) = 525,78  ( 6,04 model mm )
spacing forward to next timber (S5) = 525,78  ( 6,04 model mm )
spacing forward to next timber (S6) = 525,78  ( 6,04 model mm )
spacing forward to next timber (S7) = 538,48  ( 6,19 model mm )
spacing forward to next timber (S8) = 538,48  ( 6,19 model mm )
spacing forward to next timber (S9) = 538,48  ( 6,19 model mm )
spacing forward to next timber (S10) = 500,38  ( 5,75 model mm )
spacing forward to next timber (S11) = 500,38  ( 5,75 model mm )
spacing forward to next timber (S12) = 551,18  ( 6,34 model mm )
spacing forward to next timber (S13) = 449,58  ( 5,17 model mm )
spacing forward to next timber (S14) = 454,66  ( 5,23 model mm )
spacing forward to next timber (S15) = 563,88  ( 6,48 model mm )
spacing forward to next timber (S16) = 563,88  ( 6,48 model mm )
spacing forward to next timber (S17) = 561,34  ( 6,45 model mm )
spacing forward to next timber (S18) = 561,34  ( 6,45 model mm )
spacing forward to next timber (S19) = 454,91  ( 5,23 model mm )
spacing forward to next timber (S20) = 650,24  ( 7,47 model mm )
spacing forward to next timber (S21) = 650,24  ( 7,47 model mm )
spacing forward to next timber (S22) = 650,24  ( 7,47 model mm )
spacing forward to next timber (S23) = 650,24  ( 7,47 model mm )
spacing forward to next timber (S24) = 650,24  ( 7,47 model mm )
spacing forward to next timber (S25) = 650,24  ( 7,47 model mm )
spacing forward to next timber (S26) = 454,91  ( 5,23 model mm )
spacing forward to next timber (S27) = 551,18  ( 6,34 model mm )
spacing forward to next timber (S28) = 551,18  ( 6,34 model mm )
spacing forward to next timber (S29) = 449,58  ( 5,17 model mm )


I have looked the through the topics, and I have not so far been able to find a related topic for this problem. But I assume that I might use the wrong key words in my search.



I would be happy to be able to fix it myself, but I would as well be happy to get hint for a direction to solve the problem.



I am looking forward to the comments and help and any details I might have missed!


Rasmus

Hi Rasmus,

You need to use the shove timbers feature, you select the timber you want to move and the use the arrow keys or the mouse. You will find the shove timbers at the bottom of the real menu or control + F10.

Hi Rasmus,

It looks like the drawing of the original uses equalized timbers. You might try -

Real, Timbering, Equalized-incremental

Cheers,
Andy
