In this photo from January 16, 2012, the experts from California Restoration & Waterproofing Co. are continuing their refinishing of the wood and paint on the south-facing side of Sinai. The two historic cars (age, about 100 years each) have been back on their tracks -- in the hot sun and occasional rain -- for more than three years. The restoration team is making good progress on Sinai and hopes to turn its attention to Olivet in a day or two.
