I would go the softwood route, or old pallet wood as Al suggested. The latter is often hard wood, and is free, a major consideration if you need a lot of it / them. As for treatment, whilst we can no longer buy creosote (unless you are a farmer), almost any of the usual preservatives will suffice. If possible, putting it in under pressure is most efficient and quicker. Doesnt need much presure, only a few psi. Way back, I used an old hot water tank, fitted as many sleepers as possible via the immersion heater hole, added creosote, sealed and pumped a few psi or air in the top with a footpump. Within a few hours, they were soaked right through. Alan Stepney http://www.alanstepney.info Model Engineering & steam engine information pages MODEL ENGINEERING DISCUSSION LIST.
