I can't take any credit for the track laying. That's the layout owner David's department. I've only laid a few inches for a new deck in a brass Overland truss bridge with full spikes and tie plates. I'm more of the electrical and signal department.
The A&O uses weathered Microengineering rail, codes 125 and 100. We have had lots of problems with the chemical treatment it received at the factory. For many years after the rail was laid, the treatment had not yet stopped. We found dark green insulating nodules growing on the rail head that had to be removed mechanically. ME had no advice regarding a way to neutralize the chemistry. We still occasionally find a new, crusty lump or two.
