Depending on when the track was last relaid on your imaginary prototype, you might consider changing the points at the start of the station throat.

At the moment you have 2 facing points off the main line, but in the late 19th century - and until the track was re-laid - many stations like this would have had the goods yard track coming off the run round loop and over the platform line on a diamond. Sounds crazy perhaps, but it avoided as many facing points as possible and having to install more than one facing point lock.

GWR locations (and others) did have this arrangement - though I could not claim it was universal. It would make your layout just that little bit different though.

Thankyou for your input.

I know that was the arrangement at Mortonhampstead, I will perhaps have a look at the area on the boards to see whether something like that is possible. I really wanted to get all of the pointwork on just two station boards, allowing a little countryside scenery between the station and the fiddle yard.

Justifying a headshunt from the 2 goods yard roads is probably unnecessary too, although I might make it into a private siding of some sort (and shorten it accordingly - but again I didn't want to lose too much countryside on the station approach).

The headshunt would be very awkward to operate anyway - in real life, I suspect it would have been operated using fly shunting, or similar.

You will need to watch the sharpness of the curves on the platform road - they might make coupling and uncoupling difficult.

I'd be tempted to rotate the platform road such that none of it is not parallel to the baseboard edge. This would also have the benefit of smoothing out the line and producing more flowing track. Perhaps the centre of rotation could be the end of the platform road and the right hand three quarters of the middle board stays as it is. Everything should still fit in as it is now.
