I attach an incomplete box file that I am playing with at the moment. Towards the right of the plan, there are two turnouts overlaid over each other (templates 38 & 41) which I intend will eventually become a tandem turnout. However, I have no experience at all of tandems. Before I spend more time on them, or the track leading from them, I am hoping that someone might have a look and see if they look OK. In particular, given the switch and crossing placings, does it look build-able? Any other comments will be welcome too. Thanks, in anticipation, Bill |

Hi Bill. I have downloaded your trackplan and will come back to you shortly. Tony. |

Hi Bill. Interesting project. I have made a couple of minor alterations to your plan. I have shifted the second turnout of the pair away from the first switch very slightly to allow more room for the switch blades to open and also give better matching of the timbering for the third crossing. If you make template 41 visible again you should be able to see the difference. I have also changed the timbering from equalised to right angles to the main road for both turnouts, this makes them parallel with each other and easier to align later. The change has altered the position of the diamond slightly too. I don't think there would be too many problems building it although the radius of the second turnout road seems rather sharp to me. I think you may also have fun linking the middle road of the tandem to turnout 44 (I assume this is where it is going) which may need to be shifted to the right somewhat to ease the alignment and you are correct to want to make sure the tandem is workable before proceeding further to avoid having to redo to much. Good luck with your project. Tony. |

Hi Bill, A further change I think you need to make is to change the V-crossing on the first LH turnout (49) to curviform pattern. Otherwise you have an unsightly reverse curve in the vee splice rail. Put the peg on CTRL-0 first. You can use make branch track to link it back in to existing tracks. Very often when the curving is negative like this a change to curviform is needed. To complete the tandem may I suggest you join the development group? The TDV includes the option of using a partial gaunt turnout for the middle V-crossing, which is much easier to adjust. Some notes about doing that are here: message 9841 regards, Martin. |

I'm on holiday for a week or so, so I probably won't be able to have a good look at your changes until after then. The radius is rather tight, but it is intended as an industrial layout, with 4 coupled tank engines and short wheelbase wagons. I might see if I can ease it a bit however. Bill |

I'll have a look at that. Joining the TDV group sounds like a good idea. Can you include me please. I agree to the terms and conditions you set out in your initial post. Bill |
