LIRR had a bunch of ex-Chicago South Side Rapid Transit. 0-4-4T tanks for a couple of years, used in joint service with some “El” (not “L”) lines near the Atlantic Avenue line. The SSRT was the only one of the Chicago “L” companies to use steam on the Loop.
According to a 1904 list, IC had 21 2-4-4T, 10 2-4-6T, 2 2-6-4T and 7 4-6-4T on hand. Not sure when the last one left suburban service, but at least one was serviceable for the ceremonial final steam runs.
