Railway sleepers partially rotten (New Ash Green DA3)

Railway sleepers being removed form my garden. Please note they are partially rotted! On one side they look ok, but at the back they are rotting. Hence why free. Don’t know if of any use to anyone, but if they are you are welcome to collect them. They are thick at 5” deep and 0” tall, lengths vary from 30” to 6 ft long. Collect new ash green
