Well, yes and no. Yes, DL is getting a fifth locomotive, but it will not be the one formerly operated at WDW. That locomotive, a 2-4-4- Davenport Forney, was orignally slated to go to DL. DL traded their old set of passenger cars, known as "Retlaw 1" to a collector. The Davenport, however, was a LARGE locomotive. In a classic case of Disnelyand NOT doing their homework, and not relying on their own EXPERIENCED Roundhouse staff, they traded away a prime set of rolling stock for a locomotive they couldn't use, without MAJOR modifications to the line. In addition, the big locomotive would look out of place with other DL trains and scenery. That locomotive, instead, went to WDW, where it became known as the Ward Kimball.
Unfortnately, that locomotive proved too small for WDW. So, in 1999, a trade was made with Cedar Point Amusement Park in Ohio for a smaller 2-4-4- Forney, called the Maud L. This locomotive is roughly the same style and size as DRR No. 3, Fred Gurley . Legend states that the Maud L was named for the mistress of the plantation owner who operated the locomotive on a sugar plantation in Louisiana. Built in 1902 by the Baldwin Locomotive Works, she has been undergoing a slow and sometimes painful restoration process by Disney Roundhouse personnel.
So, Disneyland will soon have a fifth locomotive, the only engine in the Disneyland fleet NOT named for an executive of the Santa Fe Railway, and the second locomotive in the Disney empire to bear the name Ward Kimball.
