|Hannibal and Saint Joseph Railroad 2-6-2 Class R-2 687, delivered as number 841, at Philadelphia, Pennsylvania on an unknown date in 1901, photograph by the Baldwin Locomotive Works, Chuck Zeiler collection. Number 687 was built by Baldwin in 1901 (c/n 18824), renumbered in 1904 to CB&Q 1734, sold for scrap in September 1948. The following is from the book, Steam Locomotives Of The Burlington Route, by Bernard G. Corbin and William F. Kerka:
Hannibal and St. Joseph Railroad No. 570 to 573 were ordered originally as H&StJ 681 to 684. These were changed to KCStJ&CB, same numbers but, as the engines were to be used on the H&StJ, they were lettered with the initials of that road, and H&StJ 840 and 841 were ordered as H&StJ No. 686 and 687. These were changed to CB&KC, same numbers, but also lettered for the H&StJ. These changes were made at the Baldwin Works before the engines were delivered, which explains why the Baldwin Works issued a photograph of H&StJ 687 while the records show the engine to have been delivered under another number.
