I wonder if any of you can help me.. I have been working a little on my branch layout with passing station and I am wondering if the left hand side points look right? Basicially it's a LH point that leads into the goods yard but it also connects to another LH (curviform crossing) which forms the loop. I'm not sure if it's me or not but something seems a little off. Anyway I am trying to fit this in with a big enough station loop area for 4 coaches and a loco. My aim is also to keep to a minimum of 3ft radius curve for the scenic stuff. The right hand side cannot move any further across as that's where the curve to the fy starts. Oh and do I need trap/catch points on a platform passing station like that? Thanks |

Hi Michael, The loop turnout needs to be a regular crossing, not curviform, in a crossover situation like this. Also in a crossover both turnouts are normally the same crossing angle. I suggest: 1. on the loop turnout put the peg on CTRL-0. 2. change it to a regular crossing. 3. change the crossing angle to 1:7.5 4. such turnouts usually look better with equalized timbering. 5. on the goods yard turnout, change the crossing angle to 1:7.5 6. use the CTRL+F12 mouse action on it to extend the turnout road to fill the gap: 2_181146_140000000.png  The design could be improved for a better "flow" into the platforms by using transition curves. You would need catch/trap points on the exit from the goods yard onto a passenger line. regards, Martin. |

Thanks Martin, It looks better now for sure.. No idea how you make a 7.5 crossing but I shall cross that bridge later.. I have put together the rest of the track around the station and goods area (still needs a cleanup) Where is best to put the transition curves? Just after the points as it enters the station? Many Thanks |

Hi Michael You use the F5 function to alter a common crossing. Phil |

Hi Michael, Here I have smoothed out the curves with some transitions to show the effect. It meant moving the platform roads a bit further north. I also changed the crossover back to 1:8 -- it could go a bit longer to 1:9 or so, to ease the inside radius on the yard turnout. The turnouts are in the transition zone, but I won't tell anyone.  I also moved the catch points back as far as they would go so that a derailed vehicle is clear of traffic using the crossover road. 2_181448_250000000.png  .box file attached. cheers, Martin. |

Wow! Yeah that looks way better, Thanks very much I see what you mean about maybe making it a 1.9 as that turnout is probably on the limit of being abit of a tight radius at 33.5" Not sure what the limits are for 4-SF but it's in the green so at least I have some options there I think I will print it off tomorrow and lay it out and see how it looks in situ. Thanks very much again |

Hi Michael, Here's a version with C-10 turnouts. The smallest radius is 39.5". cheers, Martin. |

Hi Michael, Your headshunt was too close to the running line. The regulations require 10ft way (i.e. 182 inches centres) between running lines and goods loops or sidings. I have moved it to the required spacing, and also increased the track spacings generally, as the running clearances were a bit tight at standard 6ft way at the end of the platforms. I increased the platforms spacing by 2ft to 8ft way (158 inches centres), which also makes a bit more room for ground signals, etc. 2_191010_340000000.png  File attached. cheers, Martin. |

I have worked on the bottom half of the layout... I hope it looks ok.. I have tried to use transitions where possible. The c10 point leads into an industry area (which I will design later) as the single track running line runs off to the fiddleyard behind it. I couldn't fit in a smaller point without the radius being a little tight. I have 3ft deep baseboards. (ignore the vertical bit of track.. that's a marker to show where my FY track enters the scenic section) | ||
