This string of motors awaiting disposition at Detroit in March 1954 included members of classes R-1 and R-1a. They had not been displaced by diesels, but by R-2 electrics brought from New York City. Behind No. 161 of class R-1 are No. 169 of class R-1a, No. 165 of class R-1, and several others. The R-1a class came from General Electric in 1914 and mustered 50,500 pounds of tractive effort. All the R-1s had a wheel diameter of 48 inches. Though not diesels, one could say that these engines were among the original "tunnel motors." Not long after I took this photograph these steeple-cabs were sent to Ohio for scrapping, and met their fate in 1956.
