Re: [External] [CBQ] How was Soda Ash and Silica Sand transported?

["William Hirt" <whirt@fastmail.com>]

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.

To back up Eric's comments, a quick perusal of the American Car and Foundry collection of photos in the Barriger Archives on Flickr (https://www.flickr.com/photos/barrigerlibrary/albums/72157649155982802) turned up ACF two-bay covered hoppers built as early as 4/42 (Lot 2338 for the MEC) and 9/42 (Lot 2431 for the CNJ).  These were 1,796 cubic foot capacity cars for cement loading.  So while covered hoppers may not have been in widespread use until the mid-1950s, they were certainly around more than a decade earlier.
