So it comes to pass that every engine makes a regular visit to the shops, generally at periods of from ten to fourteen months, depending upon the service in which it is engaged. On some of these visits, it will be pretty completely dismantled, and a travelling crane running the full length of the erecting shop will soon lift the heavy boiler from frame and wheels and carry it down to the boiler-makers, with no more difficulty than an automatic package carrier in a dry-goods store would have. There is a deal of pride and rivalry between the men as to the facility and speed that can be shown in taking an engine in hand, dismantling it completely, making necessary repairs, setting it up again and placing it in service once more. The men of the Erie shops at Hornellsville succeeded in doing the trick a year or so ago in the remarkably short time of twenty-four hours. In that brief time a locomotive came in from the road, bedraggled and begrimed and marked "TBMF" for the benefit of the shop-men. "TBMF" translated means "Tires, Boxes, Machine, Flues," so specifying the engine parts to be repaired. In the slang of the repair shop the men say "To Be Made Fast." These four requisites are the ones most necessary to make the locomotive fit for from 50,000 to 75,000 miles of service before she shall again turn into the shop. To make them in twenty-four hours required some planning on the part of the Erie shop foremen at Hornellsville, and yet it was only a few weeks after 1734 had come out of the Hornellsville plant fit for revenue service in a single day and night, before the men of the rival Susquehanna shop wished a chance at a contest of that sort. "TBMF" generally keeps a locomotive in the shop for from a fortnight to three or four weeks; the Canadian Pacific considered that it had done a remarkable thing in effecting these repairs on a locomotive, with a super-heater, at its Winnipeg shops in 57-1/2 hours. The Hornellsville record was one most remarkable. But the Susquehanna shop men took 2018 in off the road after 70,000 miles without repairs; took in the big puller at 7 o'clock in the morning, made the heavy "TBMF" repairs, and turned her out for revenue service at 7:34 o'clock in the evening--thirteen hours and thirty-four minutes. At midnight she was pulling a heavy through freight west once again, and a most astounding record in American shop work had been consummated. * * * * *
