Hi all Using the help video of the making of a double junction I have got to the position where the new inner track is extended around until it meets the straight track as shown. Fine so far, however when I make the second turnout to connect to it there is a joggle in the track (not like in the video!). Looking closer at this track, if it is continued until it meets the straight track (as if it was part of a turnout) the tracks do not co-incide, there is a slight offset. Is that correct? I assume not! So what have I done wrong? Upload of work so far included Cheers Keith |

See at 1min:45secs in the video. Here is your completed double junction attached. (Over to you for the timbering.) p.s. A-6 is very sharp deflection for a running line junction. Are you sure you don't have room for at least a B-6? The turnouts would be longer, but the radius slightly tighter, so the overall size not much different. regards, Martin. |

So what have I done wrong?Hi Keith, So far It's just a case of getting my head around the program I had another go and ended up with a better fit (the V crossing ended up at 1:5.92) To connect with a section of straight track further on the overall radius of the inner track should be about 42" average over about 6ft length so plenty of scope for adjustments. The main reason of doing it this way is the curviform layout of the junction which saves space anyway. The current layout using Peco track is a 36" turnout and the radius opening out to more more than 48" Latest effort attached. Cheers Keith |

Hi Keith, Looks good.  Now you can practice timber shoving.  Don't forget to shift it all into the positive quadrant if you intend to print it. regards, Martin. |
