Here are pictures of my finished railway sleeper wall project.
RAILWAY SLEEPERS USED:
Dutch oak grade 1 used railway sleepers

Thanks for the photos, Noel. Slotting railway sleepers into steel RSJs or I beams, is such a strong and practical way of constructing a retaining wall, and using thick oak sleepers makes it even more sturdy.
