Are those purpose-made 'sleepers' rather than actual railway ones? I would think the old wooden sleepers have all been reused by now. That's a pretty steep slope up beside the house. They need some steps.
Hope things are good with you and weather is kind.

Yes they are all new oak sleepers. The reclaimed ones are starting to get a bit scarce now. Weather hasn’t been too bad lately, but I think it’s all going to change very soon. Thanks for the support @steevc 👍
