... ) instead of the 1:32 switches used here. But that can have radius consequences if the slip is curved. However, you don't really need any of this at present. Like timber shoving, it is a waste of effort adding slip switches and slip roads to a diamond-crossing until the track planning is finalised (except perhaps to check that the radius will be acceptable). Add the slip roads when you are sure the diamond-crossing is not going to be changed. regards, Martin.

Just one question though. I have opened the file and the slip appears no problem but there is a red light warning on the information panel that the turnout radius is just 18". I'm a little surprised by this. Perhaps you can clarify for me? posted: 11 Nov 2007 16:36 from: Martin Wynne Gordon S wrote: ...
