I am returning to Templot having not used the software for a number of years and finding myself to be a little rusty. My current layout plan involves a through station with a run-round loop beyond the station platform. A couple of sidings are to be positioned behind the station which have exited off the run-round loop via a trailing 3-way. As per my sketch.

You can see from the attached box file that I am trying to create the return curve off the mainline into the loop. I need to also install a trailing 3-way almost directly off the turnout from the mainline. I managed to create the return curve using the S-curve reverse transition function but once aligned with the loop the track join was right where I wanted to install the 3-way. Can anyone offer any guidance as to how I can achieve my aim?

Thanks,

Scott

Hi Scott,

You had an instant reverse curve in the running line, which didn't look good. I moved the turnout template 25mm to the right so that I could create an S-transition in place of the reverse curve.

I then made a branch track from the turnout, and used the make simple link function to link it to the loop.

Split the loop so that the constant 2nd radius is a separate template, inserted a LH turnout in it, and then make single-sided 3-way tandem.

No idea if this is anything like what you are looking for, but it might suggest a way forward.

p.s. It doesn't look like a single-sided tandem, but it is. The loop line is the main road, both turnouts are LH into sidings.

Box file attached below.

cheers,

Martin.

Martin,

Thank you kindly for your help. When you explain what you did it all seems very straight forward but I would never had thought of doing it that way, I certainly wasn't aware of the 'Make Simple Link' function.

With the return curve being one seperate template, on a constant radius, I can play around with the tandem later today.

Cheers,

Scott
