When all Upjohn manufacturing was located in Downtown Kalamazoo, by the mid-1930s new warehousing was needed. A warehouse was built north of Kalamazoo on Pitcher St after Mosel Ave (Building 27). Part of the attraction was this warehouse was served by two different railroads - at that time all Upjohn product moved out of town by rail. The two articles below from The Overflow internal sales magazine are from 1937.

A second warehouse on the site was added in 1941 (Building 28). However, when all manufacturing was moved to Portage by 1951 they were surplus to requirements. The photo below shows one of the warehouses in the early 1950's, unused and for sale. Building 27 was eventually donated to the Kalamazoo Foundation in December 1960 and Building 28 was sold to the City of Kalamazoo in September 1960. These two warehouses have beat the odds - they still stand and are in use. They look the same as when Upjohn owned them! 

The boxcars in the September 1930 photo below would not have been shipped from the North Pitcher warehouse as that opened in November 1937. This product would have been shipped directly from railroad spurs in Downtown Kalamazoo.
