NOTE: not all ex-rail sleepers are treated! - most are not. In NZ it is only pine sleepers with creosote for obvious reasons, theyre not hardwood!

Macrocarpa is rated as moderately durable, meaning that a 2x2inch peg of it can be expected to last 10 years in the ground. Not all hardwoods are durable; some softwoods, e.g. totara, are extremely durable. 'Durability' actually means 'poisonous to wood decaying organisms'. Therefore, ALL durable wood, whether naturally so or treated, is poisonous. What matters are a] how likely the poison is to get into something we will eat and b] how resistant our systems are to that particular poison.

I would burn the side that is in contact with the ground.

This is a Japanese technique that has been used for thousands of years. Charcoal creates a natural barrier for bugs that eat wood.
Get macrocarpa that is relatively light, easy to transport and work with, alro cheaper than other... Burn with a tourch the inside faces
