Green Bay Winona & St. Paul #20 was one of three identical 4-4-0 locomotives built by Schenectady Locomotive Works and delivered to the railroad in June 1891.  The 63" drivers and 17" x 20" cylinders were typical of much of the steam power at the time.  This was the Green Bay Route's first purchase from Schenectady (later known as the American Locomotive Company, or Alco).

The arrival of these locos marked the end of the tradition of naming locomotives for investors in the railroad -- the twenty-one locomotives which preceded it (there were two #1 and #16 locomotives on the roster at various times) were all given names - these three locos were simply referred to as #20, #21, and #22.

In early times, these locos were assigned to Train No. 1 and 2, the daily cross-state passenger train.  As heavier trains became the norm on the railroad and the locos were bumped to secondary service, the 4-4-0s were operated doubleheaded when traffic needs arose.

After a long career on the railroad, #20 is seen sitting on the "dead track" next to the turntable pit awaiting the scrappers torch, along with several other 4-4-0s and 2-6-0s were stored there. It was the oldest of a handful of 4-4-0s left -- #18 and #24 was facing a similar fate, while #8 and #23 (with #18's tender) still had a few productive years left on the Waupaca Branch.
