After dry assembling and test fitting the goods shed to station track work, I wasn't happy and decided the gable ends had to be scrapped and remade because the arch was too wide for typical 2 axle goods wagons. So made another pair of gable ends, ready for building assembly tomorrow. If at first you don't succeed try try again. Luckily I had a spare sheet of the coarse stone finish.
The gable ends on the left were the replacement versions, the right hand side are scrapped or may be used in the future for some other shed.
Dry test fitting over the track and beside the platform showed immediately the the original archway doors were too big and in the wrong place, so off with their heads, had to be redone.
