I'll be glad if any new locomotive production happens, whether 2' gauge 2-4-4T or 2-6-2 or 3' gauge 2-6-6-2 or standard gauge 4-6-0. Seems like 2' gauge is coming ahead of anything else (although the two Promontory Point engines and the V&T Lyon have been built in recent years). From the 2005 WW&F Long Range Plan:
"Some consideration has already been given to expanding the steam locomotive roster by building a replica of an original WW&F locomotive. There are some advantages to doing this, beyond filling an operational need. Given the uniqueness and scarcity of original equipment, replicating an original locomotive gives us an unparalleled opportunity to represent the original railway in a more complete fashion. The planning of such a project, followed by its execution, could draw considerable attention from the preservation community. This in turn would likely draw considerable interest, funds, and volunteers. The enthusiasm thus gained may serve to fill a void should volunteer interest wane with a lull or cessation of construction. Considering that the completion of such a project would likely be a decade or more after initial planning begins, and the need for another steam locomotive may exist toward the end of this planning period, a study of the feasibility and required resources for this project may proceed in the near future. It is important, however, that such effort in no way interferes with the goals and priorities of this planning period."
By the way, Davenport (and perhaps some Porter) business records at the University of Iowa at Iowa City Iowa. Becky Thoms is the contact person there. It appears locomotive drawings were lost in a warehouse fire.
Merrill Publishing Associates (www.merrillpublishingassociates.com) sells a CD containing Davenport Locomotive Works rod locomotive catalog (tenth edition, ca. 1927) and Catalogue of Steam Locomotive Repair Parts (ca. 1930-33).
