Milwaukee Road Mikado No. 306, seen here at Bensenville, Illinois in February 1942, came from the American Locomotive Company's Brooks works in 1918 as No. 8620 in class L3. As rebuilt with Delta trailing truck and booster she was renumbered 306 and reclassified to L3a. The L3 class had a grate area of nearly 49 square feet, with 2950 square feet of evaporative heating surface and 720 square feet of superheater surface; other dimensions are listed on the previous page for No. 302. This view of No. 306 comes from the collection of Clifford "Mike" Southard, as preserved at the Kishwaukee Valley Heritage Museum in Genoa, Illinois. She was stricken from the roster in 1953.
