I have managed at last to produce a double slip but I have two problems. The middle check rails(K crossing?) foul the curving slips. Also the tie bars seem to be crossing each other . Any advice would be welcome. When I have got the procedure right with a quite a few more tries I will perform the change of a diamond crossing to a double slip that I have in my full plan. This I have curved a little to suit the space and I would like to know if the check rails and slips will fit to the curving diamond. My practice template is attached. Graham Bridle |

Also the tie bars seem to be crossing each other . Hi Graham, The problem with the K-crossing check rails is caused by the fact that you are using overscale flangeways (G0G-F). There is some discussion and screenshots with possible workarounds in this topic: topic 324 The situation would be eased if you changed to 0-MF or 0-SF instead of G0G-F, and you would get better running too. But the only way to have a K-crossing in a slip looking entirely correct is to model in ScaleSeven, with exact scale flangeways. Those aren't tie-bars, they are drive slots ("switch drive marks"). Templot makes a guide mark where it thinks you probably want to have a slot in the baseboard for the switch drive (point motor linkage). It's purely a guide, and for slips you combine or modify them as necessary, or omit them (untick geometry > switch drive mark). The actual modelling of the stretcher bars and drive arrangements is left to you, it's not part of the rail or timbering geometry. Normally in a double slip connected to a signal box all 4 switch blades at one end move together. Slips in yards sometimes have individual hand levers for each switch, but in that case you need to check that there is clearance in the centre for both blades to be open at the same time. regards, Martin. |

Hi Martin, Thanks for your reply. I will read more on the suggestions before I start construction. regards Graham |
