As Eric and Michael noted, covered hoppers came into use by World War II. The first Q series was a 29' 3" 2-Bay ACF-type Covered Hopper. 1958 cuft. Class HC-1. Built 1940 at CB&Q Galesburg. Welded Roof. Series #180000-180099. Photo in Railway Prototype Cyclopedia Volume 30 on p95 (car 180000).
Another 50 cars were built in 1943 with 550 built between 1945 and 1948 by Havelock. Another 200 were built by Havelock in 1952.
1954 I usually consider the turning point for covered hoppers as
the larger PS-2 3-bay covered hoppers (and competitor's offerings)
came into initial limited use. An example of this on the CB&Q
is the initial 41' PS-2 Three Bay Covered Hopper order. 2893 cuft.
Built 1954 by P-S. Series #85000-85029.
