Through WED Enterprises, a legally separate entity from Walt Disney Productions, Walt Disney retained personal ownership of the DRR and financed the creation of two trains to run on it in time for Disneyland's opening day. The names of both trains contained the word "Retlaw", which is "Walter" spelled backwards. The first train, referred to by Disneyland employees as "Retlaw 1", would be pulled by the No. 2 locomotive, which was given a turn-of-the-20th-century appearance with a straight smokestack (typical of coal-burning locomotives), a circular headlamp, and a small cowcatcher. The No. 2 locomotive would pull six 1890s-style passenger cars designed by Bob Gurr, consisting of a combine car, four coaches, and an observation coach. The second train, referred to by Disneyland employees as "Retlaw 2", would be pulled by the No. 1 locomotive, which was given a late-19th-century appearance with a spark-arresting diamond smokestack (typical of wood-burning locomotives), a rectangular headlamp, and a large cowcatcher. The No. 1 locomotive would pull six freight cars consisting of three cattle cars, two gondolas, and a caboose. Walt Disney Studios built the train cars and most of the parts for the locomotives; Dixon Boiler Works built the locomotive boilers, and Wilmington Iron Works built the locomotive frames. Both locomotives were designed to run on diesel oil to generate steam. Final assembly of the locomotives and their tenders took place at the Disneyland site in the DRR's new roundhouse, which was built in one week by a construction crew directed by Park Construction Administrator Joe Fowler, a former US Navy rear admiral. The two original DRR trains cost over $240,000 to build, with the two locomotives costing over $40,000 each.
