PERRY COMO used to get request letters. We get those too, but being in the magazine trade we also receive press releases. Many extol a new or proposed railroad freight service, and often the copy is laced with enough figures to engage the editor's arithmetic.
Item I: Mobil Oil placed in service this year a fleet of 28 jumbo tank cars - 38,000-gallon, 12-wheel 70-footers- to move Tube oil between its Paulsboro (N. J.) refinery and a Cleveland bulk plant (517 miles) as well as a Woodhaven (Mich.) refinery (681 miles). The Mobil release said that each car "is expected to make two trips a month." This seemed slow, very slow, for brand-new roller-bearing equipment in assigned service, so we asked the oil company for a breakdown of the cars' activities each month. Answer: "Transit time each way is 5 to 6 days; unloading time, 1 day; loading, 2 days. Total: 13 to 15 days each round trip." Excluding loading and unloading time, that calculates out to an average running time of approximately 43i mph.
Item 2: "Canada's first predesigned unit train" was inaugurated in March. Operated jointly by Ontario Northland and Canadian National between Temagami and Hamilton, Ont., via North Bay, three brand-new 35-car trains move pelletized ore from a mine to a blast furnace on 72-hour cycles. Loading requires 2 hours; unloading 24 hours (because the mill consumes 12 carloads a shift). Thus, in theory the railroads involved have 46 hours to make the 680-mile round trip, an average speed of 14-1h mph. For the service, ON and CN jointly purchased 120 covered hoppers with mechanically operated loading and unloading hatches as well as load-compensating brakes -105 cars for the trains and 15 (or 12 per cent of the fleet) for reserve to replace cars being accorded planned maintenance. Upon questioning, CN conceded that in theory two trains could do the work of three, but the hang-up is that the operation, however predesigned, is not true-blue unit. At the mine, cars are gravity-fed down a 2 per cent grade to the loading
