I want to create two parallel tracks with the distance between them of 64.6mm. And I cannot find any combination of straight tracks that gives this distance except cutting a flex track.
How did Marklin forget? to produce such a critical straight track. I am listening your proposals.
Thank you.
By the way in C Tracks there are straight pieces of track of 77.5mm and 64.3mm which are distances of parallel tracks using narrow and wide turnouts.

If producing parallel tracks then you would use a point and a curve track, example given in my gesamtkatalog is a 2262 point and a 2232 curve. If you are wanting to have things at the correct spacing after a curve you use two different radius curves, e.g. 2231/2221 or 2241/2251

I think the issue is the length of a straight track to move from one track to the second track 64.6mm away, at the angle that the turnouts have. I too found this glaring omission many years back when trying to design my layout. Unless a new length has been added in the last 20 years, you will have to cut some track. It need not be a 2005. The length needed depends on the diagonal angle - which is determined by the turnouts being used. I have provided a calculator that can be used to determine the length needed, give the angle and the track separation (64.6) at http://layout.mixmox.com/1/calc |

I'm confused about the question as well. Does the following help?  For the slim turnout (22716), the part numbers required are: 22716-2203-2200-2202 2203-2274 Tracks are parallel with a distance of 64.6mm between them. |

And if we don't want a turnout then surely if we are going along a piece of track then put in a s shape of two 2232's we are the going straight again 64.6mm from where we started.

I think the issue I found was no transition from 57mm to 64.6mm spacing |

It looks less awkward than closing the gap on a straightaway. I think flex is the only option for this. |

If I understand correctly and if I remember correctly, the spacing between R1 and R2 was 64,6mm. The spacing between R3 and R4 and R4 and R5 is narrower at 57mm.
To go from a track spacing of R2 to R3, the use of the slim switches is required.
If you plan to have R1 or R2 curves on one end (64,6 spacing) and larger radii curves on the other end, you would need to shift the tracks using curved tracks designed to be used with the slim switchtracks to make the S-curve required or use flex track. The problem with using flex track is that this requires a minimum track length (for that section).
If you want to have a station platform area with a track separation of 57mm and still use the narrower radii curves at the ends, you would have to compensate at each end.
My solution was to use R3 and R4 which replaced the original R1 and R2 track loops which had a straight section inserted between each quarter turn, which did not significantly change the size of the loops and yielded the closer track separation.

Mike C For k-track it's actually 64.6mm between R1 - R5.  R3 doesn't officially exist but it can be made using a combination of different curves  |
