A delightful blast from the past with the D 1/3 "Limmat" steam engine from 1847 (the brown one) and the Ec 2/5 28 "Genf" from 1858 (the green one)...both are 2 cylinder engine. The passenger cars pulled are also the original (restaured) from the 1847 first train line in Switzerland between Zurich and Baden by SNB (Swiss Northern Railways)...a 20 km line (12.5 miles)
