This string of motors awaiting disposition at Detroit in March 1954 included members of classes R1 and R1a. They had not been displaced by diesels, but by R2 electrics brought from New York City. Behind No. 161 of class R1 are No. 169 of class R1a, No. 165 of class R1, and several others. The R1a class came from General Electric in 1914 and mustered 50,500 pounds of tractive effort. All the R1s had a wheel diameter of 48 inches. Though not diesels, one could say that these engines were among the original "tunnel motors." These steeple-cabs were sent to Ohio for scrapping not long after I took this photograph.
