Multi-purpose locomotive. Swedish State Railways (SJ) Class Da. Wheel arrangement 2-6-2. 3 axles powered. Jackshaft driven through gears. 2 traction tires. Illuminated triple headlight. Metal body. RELEX coupling at each end. Length over buffers 14,7 cm (5-3/4").
Used as the standard locomotive for slow passenger and freight trains. Since these machines had only one motor and the low axle loading of 15 to 17 tons, they were fitted with side rod drive so that individual wheels did not "run away" on starting.
