"The largest single order for buses ever placed" — AM General's 620

Washington, 1974

The claim. When AM General of Mishawaka entered the transit-bus business in 1974, its first great order came from the Washington Metropolitan Area Transit Authority: 620 Metropolitan buses. The company's own photographic history calls it "the largest single order for buses ever placed," and this history's AM General flagship carries the sentence at the company's strength, attributed and untested. The number and the crown are tested separately here, because they fare differently.

The record. The number is documented outside the company's telling: the trade's standard reference, Ed Stauss's Encyclopedia of Buses (1987), records the initial Washington order at 620 buses — and records the pace that followed it, some 2,250 AM General buses delivered by the end of 1975 — and the AM General file carries the production course the order began — 5,212 diesel Metropolitans and 219 trolleybuses built between 1974 and 1979. The scale of the era's ordinary business frames the claim: transit orders of the mid-1970s ran in the low hundreds — Seattle's King County Metro, to take a documented example from the county's own history, placed its first AM General order at 145 buses in 1976. No single order larger than 620 placed before 1974 was found in the record reached, and the claim was made in the order's own years, by the company filling it, not in retrospect by its historians. The crown's later course is the genre's usual one, and it is printed because it bounds the claim in time: within the decade the title was being claimed again — Pennsylvania's order of 1,000 Neoplan buses in 1982 was billed in the transit literature as the largest order in the history of buses — and in 2008 General Motors announced Washington's own potential 952-bus hybrid order as, in its qualified form, the largest single hybrid-bus acquisition in history.

The verdict. Partly supported — the strongest form the record allows. The order's size is documented in the trade's reference; the superlative is the company's; no larger predecessor stands in the record reached; and the sentence is true, if at all, only of its moment, which is how this entry leaves it. The settling check is named for the update pass: the transit trade press of 1973–74 — Mass Transit and Motor Coach Age — read entire rather than sampled, where an order of record size would have been news in its own season.
