Hi Tony,
You didn't say anything about what your intentions are for this track plan, but I assume that it is a small branch terminus and you want it to be reasonably prototypical within the available space?
At this location:

you have an instant reverse curve between two fairly sharp curves (or very sharp, in prototype terms). That's not very prototypical, and in P4 it is likely to cause running problems. At the very least you need a short length of straight between these curves. But Templot makes it very easy to insert a gentle transition curve instead. You just need to sharpen the lower radius a fraction, and them use the
make transition link function. This is a possible result:

More about that function at:

Your track plan is entirely constructed using short dead-straight B-6 turnouts, as may be found in a set-track style of layout. That's not very prototypical and is making very little use of Templot's many functions and features. If that really is the type of layout you require, you might find it easier to use a pick-and-place type of software such as AnyRail:

For a more prototypical-looking track plan, you should consider using longer turnouts for the running lines, and the short turnouts only for the yards and sidings.
To make better use of the space you might consider putting the station on a curve, as in the upper version here (with your track plan below it):

By using another transition curve at the entry into the station on the right, it is possible to use longer turnouts for the station throat and move them out partially round the approach curve. Those above are C-9 turnouts.
For the run-round crossover we can use something a bit shorter, but still need to consider we might be using large locomotives. Here they are B-7 turnouts. The crossover into the yard uses the shorter B-6 turnouts as before.
Even using these longer turnouts, the usable platform length is increased by about 150mm, as a result of curving the plan and moving the station throat out round the approach curve.
cheers,
Martin.
